The growing need for Long-Range Vehicle Access Control

Efficient and secure vehicle access control is a critical requirement across a wide range of sectors, including commercial parking facilities, residential complexes, distribution centres and industrial sites. With the increasing demand for seamless traffic flow and enhanced security, organisations are turning to advanced access credential technologies to manage vehicle entry and exit effectively.

Traditional access control methods, such as keypads, RFID proximity cards and manual verification, often cause bottlenecks, slowing down traffic throughput and reducing efficiency. For high-traffic environments such as logistics hubs and large corporate parking facilities, stopping vehicles for identification is not only inconvenient but also inefficient. This is where long-range access credentials come into play, enabling vehicles to be identified and granted access without requiring a full stop.

Among the most popular long-range solutions are Ultra High Frequency (UHF) RFID technology and Automatic Number Plate Recognition (ANPR) cameras. While both have their applications, UHF consistently proves to be the more efficient, versatile and reliable choice.

Understanding Long-Range UHF Access Control

Long-Range UHF systems utilise radio frequency identification (RFID) technology to identify vehicles equipped with passive UHF tags. These tags, affixed to vehicles, communicate with UHF readers to grant or deny access, based on predefined credentials. The technology is widely used in parking access control, gated communities, toll roads and high-security industrial sites.

Advantages of UHF Access Control:

1. Accuracy in Diverse Conditions
   UHF readers maintain high accuracy regardless of environmental factors. Unlike optical systems, they are unaffected by weather conditions, dirt, or non-standard license plates, ensuring consistent performance.
    
2. Universal Compatibility
   UHF systems are  not affected by vehicle type; therefore vehicles without traditional license plates, such as construction equipment, motorcycles and delivery trucks are not adversely affected. This versatility makes UHF ideal for diverse applications.
    
3. Speed and Efficiency
   With a reading range of up to 6 metres, UHF readers allow vehicles to pass through access points without stopping, enhancing traffic flow and reducing congestion. This is particularly beneficial for logistics hubs and distribution centres where efficiency is paramount.
    
4. Enhanced Security
   UHF technology supports advanced encryption, protecting data from unauthorised access and spoofing attempts, thereby offering a higher level of security compared to some optical systems.

Exploring Automatic Number Plate Recognition (ANPR) Cameras

ANPR systems use optical character recognition to read vehicle license plates, cross-referencing them with a database to manage access control. While widely used in city surveillance and parking enforcement, ANPR systems present several challenges when applied to high-throughput environments.

Advantages of ANPR:

• Non-Intrusive Identification
  ANPR does not require additional hardware on vehicles, relying solely on existing license plates for identification.

• Integration with Law Enforcement Databases
  ANPR systems can be linked to law enforcement databases, aiding in the identification of unauthorised or stolen vehicles.

Challenges with ANPR:

• Variable Accuracy
  ANPR accuracy can be compromised by factors such as poor lighting, adverse weather conditions, dirty or damaged plates, and non-standard plate formats.
• Limited Compatibility
  Vehicles without standard license plates, including certain motorcycles and construction equipment, may not be accurately identified by ANPR systems.
• Slower Processing Times
  ANPR often requires vehicles to slow down or stop for accurate reading, potentially causing delays during peak traffic periods.
• Vulnerability to License Plate Cloning
  ANPR systems rely solely on plate recognition, making them susceptible to license plate cloning or spoofing. Fraudsters can duplicate legitimate plate numbers and attach them to unauthorized vehicles, compromising security.

UHF Technology and the STid SPECTRE Nano

Chris Edwards, of access control specialists CIE, emphasises the advantages of UHF technology in transport access control applications. He explains, “For applications where speed and reliability are key, UHF technology offers a seamless solution. Unlike ANPR, which relies on plate visibility, UHF readers provide instant authentication, ensuring fast and frictionless access control.”

“Unlike ANPR, which relies on number plate visibility, UHF readers provide instant authentication, ensuring fast and frictionless access control.”

Akuvox SmartPlus App integrates your smartphone with intercom and access control systems

Akuvox is one of the world’s most innovative developers of smart IP Intercom systems for door entry and access control – and the Akuvox SmartPlus app ensures that any smart phone can be used as part of the system for remote monitoring, remote communication & door entry – as well as for access credentials and authentication.

Available for Android and iOS platforms, the SmartPlus app is compatible with all of the Akuvox range of IP intercoms when connected to Akuvox Cloud services.

All intercom endpoint devices on a connected intercom system (door intercoms, answering panels, IP phones, etc) can be accessed on the App. So, for instance, in the demo video we can see the Front Door Intercom, Rear Gate Intercom and the Living Room Panel are listed as individual end point devices which can be accessed from the smartphone.

Remote Intercom Call Answering and Door Unlocking

Akuvox Smart Plus provides fully-remote video call answering from your smartphone – so if someone visits your home or property while you’re out – you can see and talk to the visitor, wherever you are in the world.
If you want to allow the visitor access to the building while you’re not there, this can be done simply at the touch of a button.

Remote intercom monitoring from your smartphone

SmartPlus will also allow you to use any Akuvox Intercom devices featuring a camera for remote monitoring – and also for direct videocalls from smartphone to Akuvox device. For instance, you can videocall the family in the living room straight from your smart phone.

Generate PIN & QR Codes for temporary access authentication

In addition, for compatible Akuvox Intercom models (those featuring a keypad  or QR scanner) – the SmartPlus App can generate a unique temporary PIN Code or QR Code virtual key which can be sent to other smart phones to allow visitors limited time – or limited number of use – access. So, for instance, this is ideal for trade visitors to site, domestic staff or for deliveries, for example, in instances when you may want to allow them one-time-only access or access at an agreed time only.

Contactless Door Entry from your smartphone

And the SmartPlus App also supports contactless authentication methods including Bluetooth and NFC. So, for compatible Akuvox Intercoms, your smart phone can be used to provide convenient, touch-free door entry access credentials – ideal as part of a contactless pathway into the home or workplace in order to help prevent the transmission of viruses and germs.

What is QR Code Access Control?

There is an increasing range of options for identity authentication being adopted for access control and door entry systems – with ‘keyless entry’ and ‘contactless’ or ‘touch-free’ technologies being the focus of latest-generation devices.

QR Codes are emerging as an ideal authentication option for door entry systems – particularly for temporary applications and time-limited access permission situations such as managing entry for cleaning staff, contractors or deliveries when access to the building may be restricted to certain days of the week, certain times of the day or simply for one-time-only use.

What is a QR Code and how does it work?

QR Codes (abbreviation of Quick Response Codes) are similar to conventional bar codes, but are much more flexible and, due to their 2-dimensional structure, are able to hold much more data (QR codes are able to hold up to 2500 characters, compared to a standard bar code’s limit of just 43, therefore allowing for much longer URLs or text / character strings).

In the case of access control via QR codes, typically the entry system will include PC software or a smart phone App which can quickly and easily generate a unique QR code which can be set to allow access for a limited time period, specific days of the week, limited number of uses and entry limited to specific areas, floors or zones of the building.

Once the QR code has been generated, it can be emailed or messaged directly to the recipient (the user who requires temporary access to the building) for them to display on their smartphone device or print out if required.

A QR code-enabled Access Control or Door Intercom device will feature a scanner (in the form of a built-in camera); the user simply displays the received QR code from their smart phone to the access control device which will automatically scan it to confirm access rights within the specified time/useage criteria.

Benefits of QR Code enabled Access Control

• Keyless Door Entry
  Keyless Door Entry is increasingly popular for its flexibility both for the user and system administrator. Unique QR codes can quickly and easily be generated from a smart phone or PC app and emailed to the user in any location around the world – no physical ‘key device’ is necessary.

• Immediate access code generation
  An access QR code can be generated and distributed in a matter of seconds.
  Imagine, for instance, if a visitor arrives early and you’re not home to let them in, or a high-value package is delivered that you don’t want left outside the front door. Simply generate a unique, time-limited entry QR code and send it to your visitor who can immediately scan the code from their smart phone to unlock the door without having to wait for your return home.

• Remote Access Management
  Where high numbers of users and frequent temporary access permissions requires a significant amount of system management and administration, the ability to create and distribute access QR codes remotely from anywhere in the world allows for a highly efficient system management solution.

• Flexible, temporary access permissions
  Access QR codes can be set for time-limited and number-of-use limited entry – ideal for one-time-only delivery access or cleaning contractors, for example, who only require entry on a specific day of the week.

• Contactless / touch-free door access
  By scanning the QR code from your smart phone supports the trend for contactless door entry to help prevent the transmission of germs and viruses.

• Reduced carbon footprint
  QR codes effectively provide a ‘virtual key’, removing any requirement for physical keys, single-use plastics such as ID cards or keyfobs, or printing on paper; thereby providing a notable reduction in overall environmental impact from your security system.

• Cost effective
  This virtual key option reduces staff resource requirement, distribution time and the requirement for physical identity to key devices, thereby significantly reducing ongoing costs.

Authentication methods can be physical or digital and include formats such as RFiD, Bluetooth, Biometric, QR code scanning and many more.

You will often hear the phrases ‘multiple format’ and ‘multiple factor’ authentication referred to – and more often than not confused as the same thing!

The simplest way to define the two is by considering various authentication methods with an ‘AND’ or an ‘OR’ –
so if we consider an access reader or door intercom, it is very likely to feature a variety of authentication options. The user may be able to choose from either a keypad OR Bluetooth OR face recognition – any one of these choice of methods allowing access. And this is the definition of multiple format.

Multiple Factor authentication, on the other hand, will usually be applied to a reader or intercom for increased security – where 2-step or 3-step authentication is required to confirm a single identity. For example an access reader may require keypad PIN AND Bluetooth authentication or NFC AND fingerprint reader.

Contactless authentication allows residents and staff to confirm their unique identity in order to allow access to the building. There are an increasing range of contactless identification methods available, from the conventional RFID key fob or ID card, to the latest in AI-powered biometric identification such as face or iris recognition.

Contactless authentication methods:
	RFID – (radio frequency identification) the most common ‘contactless’ radio frequency authentication method used in ID keyfobs and cards. Available in various frequencies. Available in both 126kHz and the more secure 13.56MHz versions. Secure RFID – Access Control units with secured RFID can read a card’s PAC ID (if the card or fob supports it) or Serial Number, whereas the normal module only reads the card’s Serial number. You can choose in the allowed card types which the module will read – PAC or Serial Number.
	NFC – (near field communication) is the latest generation of RFID contactless communication. It is the same technology used for contactless payments from credit/debits card and increasingly from your smart phone or smart watch. NFC allows for short range, secure access authentication using your smart phone as a ‘keyless’ identification device. Smart phone keyless entry can provide significant savings on time and cost, compared with physical keys or ID cards/fobs and makes user account management easier and more efficient.
	Bluetooth (BLE) – (Bluetooth low energy) one of the more recent options for keyless entry via smart phone, Bluetooth Low Energy provides a contactless identity verification method with reduced energy consumption, making it a increasingly popular choice for authentication via portable devices. BLE allows for keyless entry without significantly draining users’ smartphone batteries.
	QR Code Scanning – ideal for single-use or temporary access permissions (eg. parcel deliveries or service staff), a unique QR code can be generated with limited time/date/use quantities and sent to a visitor’s smart phone to be scanned at the access control endpoint device. An access QR code can be generated and distributed in a matter of seconds. Imagine, for instance, if a visitor arrives early and you’re not home to let them in, or a high-value package is delivered that you don’t want left outside the front door. Simply generate a unique, time-limited entry QR code and send it to your visitor who can immediately scan the code from their smart phone to unlock the door without having to wait for your return home.
	Face Recognition – This form of biometric authentication uses a high resolution cameras and AI technology to scan each individual registered user’s unique facial features for identity verification. It’s clear that secure, hands-free technology such as this is a vital part of future-proofing new buildings to help combat the spread of viruses and infection; whether it be prevention of COVID-19 or regular seasonal bugs, colds or flu.
	Iris Recognition – This form of biometric authentication uses a high resolution scanner for highly secure authentication via iris recognition.
	ANPR (Automatic Number Plate Recognition) – ANPR is a technology that uses optical character recognition on images to read vehicle registration plates to create vehicle location data.

What is contactless access control and door entry?

Contactless or touchless access control provides fast and secure access through doors, gateway & barriers, personnel turnstiles, etc without the need of physical contact such as fingerprint readers, keypads etc. Instead, contactless or frictionless door entry and access control methods such as biometrics, BLE, RFID and smartphone keyless entry are quickly becoming the entry options of choice.

Why is contactless access control important?

Post-covid, there is a strong reaction against the physical touching of devices, furniture etc in the workplace, leading to the latest architectural trends in ‘contactless pathways‘. There is also an increasing adoption of  contactless as more technologies are integrated with our smartpones and devices are controlled from phone apps.  Contactless is also about the user experience; people want things to be fast and easy and the only way to deliver this within access control is using fast, simple, contactless access control authentication methods.

What are the benefits of contactless access control?

• Reduces touch points at entry / exit locatgions which helps prevent spread of viruses and provides a more confident user experience
• Eliminates the need for person-to-person interaction in reception / lobbiy areas which can increase profitablility for businesses as less staff are needed for managing security of the building.
• Provides real-time data of building occupancy.
• No physical key capable or being lost or stolen.
• If your entry is via smartphone and you lose it, it is easy to block/cancel the ‘key’ on your lost device and re-assign to a new one.
• If using biometrics for entry – you are the key which cannot be lost. This also eliminates the need of physical keys and smart phone for entry.
• Remote access control – using cloud technology, allows you to both control and monitor access in homes from a remote location. You can add and remove access permissions, monitor and track access activity in your premises and lock/unlock the doors!

What contactless access control methods are there?

• RFID (keyfob or card)
• Bluetooth/BLE  (smartphone)
• NFC  (smartphone)
• Biometrics
• QR Code scanning (temporary key)

What is RFID access control?

Radio Frequency Identification (RFID) is a wireless signal transmission technology frequently used in access control and door entry systems, which allows only authorised/registered users to enter secure spaces. RFID uses radio waves to read and capture data stored on tags (such as cards or key fobs) to provide unique information for the subject or individual.

What is BLE access control?

BLE (Bluetooth Low Energy) is also known as Bluetooth 4.0. When comparing Bluetooth Low Energy with standard Bluetooth, the main difference is in BLE’s low power consumption. With Bluetooth Low Energy’s reduced power consumption, applications can run on a small battery for up to 5 years. This is vital for applications that only need to exchange small amounts of data periodically.

In Access Control applications, therefore, BLE helps to significantly increase the battery life for users’ smart phones (compared with standard Bluetooth transmission).

In addition, as wireless, battery-powered access readers enter the market, Bluetooth Low Energy will become the transmission technology of choice for increased battery life.

Exactly the same as Bluetooth, BLE operates in the 2.4 GHz ISM band. However unlike original Bluetooth, BLE stays in rest mode until a connection is initiated. BLE’s actual connection time is a few mS, whereas Bluetooth takes around ~100mS. The reason the connections are short, is that the data rates are so high at 1 Mb/s.

An example of a Bluetooth-based mobile access control technology is 2N Wavekey.

What is 2N Wavekey?

2N WaveKey is 2N‘s patented technology for mobile access control. 2N Wavekey allows security system administrators to generate and distribute access credentials to the user in a seconds, using a simple web interface and remote ‘mobile key’ distribution. There is no requirement to meet the user in person to provide physical credentials of keys. Wavekey stands out as it offers mobile credentials free of charge which are simple to distribute without the need for cloud connection.

What is NFC access control?

NFC Access Control (Near Field Communication) allows for keyless and frictionless door entry using a smart phone device for authentication.

This short-range transmission radio frequency technology is a standard feature of most smart phones and is the same technology used for contactless payments from your phone or smart watch.

Access and Intercom system manufacturers are now incorporating NFC reader technology into access control and door intercom devices as a standard option as the trend for secure,convenient, wireless door unlocking becomes a growing requirement for residential and commercial users.

What is QR code access control?

QR Codes (Quick Response Codes) are similar to conventional bar codes, but are much more flexible and, due to their 2-dimensional structure, are able to hold much more data.

In the case of access control via QR codes, typically the entry system will include PC software or a smartphone app which can quickly and easily generate a unique QR code which can be set to allow access for a limited time period, specific days of the week, limited number of uses and entry limited to specific areas, floors or zones of the building.

Once the QR code has been generated, it can be emailed or messaged directly to the recipient (the user who requires temporary access to the building) for them to display on their smartphone device or print out if required.

A QR code-enabled Access Control or Door Intercom device will feature a scanner (in the form of a built-in camera); the user simply displays the received QR code from their smart phone to the access control device which will automatically scan it to confirm access rights within the specified time/usage criteria.

What is Biometric access control?

Biometrics use physical attributes of a person’s unique identity this is typically fingerprints, retina scans, or facial scans. The main purpose of biometrics in access control is to verify someone’s identity in order to prevent unauthorised people from accessing a building/area.

		Face Recognition – This form of biometric authentication uses a high resolution cameras and AI technology to scan each individual registered user’s unique facial features for identity verification.
		Iris Recognition Authentication – This form of biometric authentication uses a high resolution scanner for highly secure authentication via iris recognition.
		Fingerprint Scanning – This form of biometric authentication uses a finger print reader to confirm authentication via the users unique finger print.

There is a vast range of door intercom products and system options on the market to choose from, so having a detailed and considered understanding of how – and why – each individual system will be used is key to finding the right choice of products to deliver the most successful results.

What is a Door Intercom System?

A door intercom system provides communication between visitors and residents (or staff) in order to verify the visitor’s identity before remotely allowing them entry into the building. In its most basic form, a door intercom system will normally comprise of a two-way communication system using audio-only or audio & video between parties and will form part of the building’s access control infrastructure to control entry and exit through doors, gates, car park barriers, etc.

Door Intercoms are available with a huge variety of functions and specifications to meet the needs of differing applications and scale of property or campus.

Door intercoms are also frequently referred to under a variety of different names including door phones, door stations, door entry systems, video intercoms, video entry panels and more! Most recently, the growing range of smart door bells could also be considered as a simple form of door intercom – usually allowing remote communication between the visitor at the door and the resident via their smart phone.

How to choose a door intercom device

To provide the most effective door intercom system – focussed on a combination of security and usability – a number of factors need to be taken into account, particularly when choosing the ‘endpoints’ of the system; the actual door intercom stations:

• How many intercom units are required?
• Indoor or Outdoor devices?
• Audio-only or Audio & Video Intercom?
• Door Intercom or Access Proximity Reader?
• What Call function is required?
• What access authentication methods are required?
• How many users on the system?
• Flush or Surface mount?
• Wired or ‘Wireless’ devices?
• Aesthetics and Size

How many intercom units are required?

In its most simple format, a door intercom system requires a minimum of two ‘endpoint’ stations; the outdoor ‘calling’ unit at the entrance from which the visitor calls the resident and the indoor ‘answering device’ for the resident.

In a small home system, a simple one-to-one system such as this may be adequate; however, in most instances, a door intercom system will need to provide for multiple entrances and exits – as well as multiple apartments, floors, zones or offices.
Therefore, a detailed survey of all call points, access points and answering points is essential in order to understand how many devices are required and to choose the right intercom models to meet the demands of the system.

Indoor or outdoor intercom devices?

Door Intercom devices are commonly seen at main gate and main door entrances and these units will have higher protection ratings to proof against weather and adverse weather conditions.
Outdoor intercom products should have an IP rating (ingress protection rating) to signify the device’s suitability to stand-up to long-term adverse weather conditions.

Outdoor intercoms may also be available with optional ‘rain hood’ back boxes to offer even greater protection from rain (and often from direct sunlight to shade the device’s camera).

Indoor intercom devices – both intercom calling and answering devices – are much less prone to these harsh conditions and, therefore, may have either lower IP ratings or no rating at all.
However, IP rated ‘waterproof’ intercom devices may be specified in some indoor applications where high moisture is a consideration (such as swimming pools / leisure centres, clean room environments and cold storage warehouse facilities.)

Impact Protection Ratings (IK ratings):

In addition to devices having an IP rating, they may also have an IK rating – the device’s impact protection rating, signifying its ability to withstand higher levels of abuse in public access, harsh environment and high risk areas.

Door intercoms with a high IK rating may often be referred to as ‘vandal resistant’ products.
Indoor devices are much less likely to have an IK rating – though in some high risk areas such as prisons and secure units, for example, this ‘vandal resistance’ will still be required for both indoor and outdoor locations.

Audio-only or Audio & Video Intercom?

As a communications device (often referred to as a ‘door phone’), all door intercoms will feature audio calling, allowing the visitor and the resident to speak with one another remotely to identify the visitor before allowing access. For a simple, low-risk remote door opening system, this may be sufficient.

For better identification of visitors, however, the majority of door intercom models now also feature a camera, allowing the resident to see the visitor’s face. Cameras in most latest-generation devices will be high definition, colour cameras and, increasingly, will feature low-light technology for improved picture quality at night.

Why do some Door Intercoms have 2 cameras?

Some door intercom models may feature two cameras, though only one of them will be used for actual video transmission. A second camera is likely to be used for additional functionality such as face recognition authentication and QR code scanning for temporary key access.

Additional connected cameras

Some intercom manufacturers also allow additional ‘third-party’ CCTV cameras to be connected to the intercom system; in effect, allowing multiple camera angles to be viewed by the resident for increased security when identifying visitors to the building. For instance, in higher risk areas, the resident may wish to see if anyone is trying to gain elicit access to the building by hiding out of view of the intercom device’s standard built-in camera. In such a case, additional CCTV cameras may offer alternative views of the front door entrance and surrouinding area before the resident remotely unlocks the door.

Door Intercom or Access Control Reader?

Choosing between a door intercom device or an access control reader is a simple case of understanding whether or not communication is required between two individuals (eg. visitor and resident). If the system requirement is for the visitor to identify themselves to the resident (or security officer, for example) to allow them access, then a door intercom device is required.

However, if access can be gained without the need to communicate with someone – using authentication methods such as PIN codes, RFID cards, smart phone, etc, then an access reader (not featuring audio & video) may be the correct option.

What Call functionality is required?

Door intercom devices are available with a range of different ‘call’ functions (ie. how the visitor calls the resident). Options include:

• Call Button(s)
  Single or multiple call buttons which are associated to specific answering ‘destinations’. For example, a 4 x call button intercom might allow visitors to call ‘Reception’, ‘Main Office’, ‘Concierge’ or ‘Security Office’. This simple call functionality method is easy to use, but strictly limited in the number of ‘destinations’ due to the required number of buttons (this method would not be appropriate for a 100 apartment building, for example).

• Keypad
  Physical or digital keypads feature on many door intercom models which function for both access authentication (PIN codes) and for ‘dialling’ an apartment number to call the resident. This method allows for a greater number of ‘destinations’ on the system than the limited individual call button method.

• Digital Phonebook
  Some latest-generation door intercoms feature digital touchscreens to provide many similar functions to a smart phone. This allows for a flexible user interface and for a digital phonebook of residents, offices, etc in the building to be listed on the devices and called at the touch of a button.

Digital phonebooks are extremely flexible, supporting very high numbers of destinations, as well as allowing for digital labelling of apartments (using either apartment numbers or resident / company names). Intercom digital phonebooks will also provide easy search facilities and often have the ability to add images and logos if required.
Ideal for multi-resident buildings such as apartment blocks, student accommodation, multi-user office buildings and MDUs.

What access authentication methods are required?

Door intercom devices will normally also provide access functionality and double-up as the door or gate’s access control proximity reader.

Intercom systems are available with a wide range of ‘authentication’ methods such as RFID Card or fob, PIN code access, fingerprint readers or face recognition.

Due to the COVID pandemic, there has been a prodigious rise in the trend for ‘frictionless’ (also referred to as ‘contactless’) access control to minimise the number of contact points for residents and visitors entering and exiting buildings.

• Frictionless Access Authentication

Frictionless authentication provides a multitude of benefits to the user, not least being the reduced risk of virus transmission from contact points. Particularly, keyless entry via smart phone or biometric face recognition can be faster, more convenient and more flexible with regards to user account management by the property or security team.

Frictionless / keyless access systems allows the management team to add – and, more importantly, remove – users from the system directly from a PC / smart phone management application without the need for distribution of physical key / identity devices.

• Multiple-factor Authentication

Higher levels of access security can be achieved using multiple-factor authentication (often also referred to as ‘dual authentication’), when a combination of two or more identity verification methods is required to allow entry. For instance, a system may require the user to scan their smart phone for Bluetooth or NFC and enter a unique PIN code into the device’s key pad.

Multiple-factor authentication should not be confused with multiple authentication methods; many door intercom and access control devices will feature a variety of verification methods to choose from, whilst only requiring the user to provide one identifier for entry (eg. either Bluetooth or NFC or PIN code).

How many users on the system?

The number of users will also be a factor in your choice of door intercom devices. And ‘users’ may be defined as the number of ‘residents’, ‘personnel’, ‘number of apartments / offices’, etc.

How does the number of users affect choice of Door Intercom?

• Licences

A door intercom system is likely to require user licences dependent upon the number of ‘endpoint’ devices on the system (ie. the number of door intercoms, answering panels, proximity readers, etc).
If resident users are accessing the intercom system remotely from their smart phones, then app licences may be required per user. Licences are likely to be chargeable per endpoint or per user and may be purchased in quantity breaks to save costs.

• Registration Management

Registering users to the system – as well as removing and amending accounts – may be managed in different ways dependent upon the number of registered user accounts at any one time and the frequency of changes. Choosing a product with a management application / software scaled to meet the needs of the quantity of user accounts on your system will have a significant effect on ongoing staff resources, costs and security.

• Number of Call Buttons or Digital Phonebook

The number of destinations / apartments / offices in the building will also affect your choice of door intercom device. For small numbers (perhaps 1~10; maximum 20), then individual call button devices will be the easiest and most cost effective option. However, for large numbers of destinations, a door intercom featuring a digital phonebook – which may have scroll or search facilities – will provide the best option for visitors to find and call the right person.

Flush or Surface mount?

Choosing between a flush or surface-mount Door Intercom device may simply be a personal aesthetic preference. However, there are a number of factors to consider when choosing between the two installation formats…

• Ease of installation

Surface-mounting a device will be the quickest and easiest installation option as the device / mounting plate will simply screw to the wall.
Flush-mounting will require cutting a recess into the wall and fitting a back box. Where the wall material is brick, block or concrete, for example, flush-mounting will have a significant impact on the time and cost of installation per device.

• Weather Protection

A flush-mounted device is likely to be better protected from rain and adverse weather conditions as the majority of the device will be protected within the wall. However, ‘IP-rated’ weather-resistant, surface-mount door intercom models are readily available and optional ‘rain hood’ units may also be available for further protection.

• Damage Protection

Similarly, flush-mounted devices are less susceptible to accidental or deliberate damage as the unit is protected on 5 of the 6 surfaces of the unit. In addition, as a flush-mount unit does not protrude from the wall, it is less likely to be accidentally knocked or caught by passers-by.

Wired or ‘Wireless’ devices?

To clarify, though some intercom models may be promoted as ‘wireless’, there is no such thing (at the time of writing!) as a fully wireless door intercom device.

However, in order to reduce the amount of cabling required (particularly for installations located at gates or barriers some distance from the main building where Ethernet cabling is unavailable), wireless data connectivity using LTE technology is available in some door intercom models. LTE ‘wireless’ intercom devices do still, however, require power – which, of course, is not available via PoE in this instance, so a mains power supply is still required.

Aesthetics and Size

As a door intercom is likely to be the ‘first point of contact’ for visitors entering your building, the design and style of the device may be a key deciding factor in your choice. Specific ‘vandal resistant’ models are more likely to have an industrial look about them, whereas some devices may be designed to provide an impressive first impression, in some cases to the extent of providing a form of ‘virtual concierge’ service to visitors.

Digital touch screens are increasingly forming the basis of the intercom user interface, which in some cases may be customisable to match the design and branding of the building or company.

In addition, size of device is also a consideration. Space may be at a premium and smaller door intercoms are frequently the preference. However, in larger buildings – particularly unmanned entrances or lobbies – larger devices will provide an overt, eye-catching ‘point of contact’ for visitors.

When it comes to access control in volatile environments, safety is not a luxury – it’s an imperative. From oil refineries and chemical plants to grain silos and food processing facilities, industries operating in hazardous zones face a hidden threat: explosive atmospheres.

In such high-stakes settings, even the smallest spark can be catastrophic. That’s why ATEX approved access readers play a vital role in securing these environments without compromising safety. One company leading the charge in this domain is STid, a global expert in secure, ruggedised RFID solutions.

What is ATEX Certification?

“It’s not about surviving an explosion. It’s to keep sparks within the casing itself, to stop anything from sparking outside, which could cause detrimental damage.”

“ATEX is an explosion-proof certification,” explains Alex Berger of STid in a recent interview at The Security Event 2025. “It’s not about surviving an explosion – it’s about preventing one from ever happening.”

ATEX (from the French ATmosphères EXplosibles) is a European certification standard ensuring that electrical equipment does not ignite flammable gases, vapors, or dust. STid’s ATEX & IECEx certified access readers are designed specifically for these extreme conditions. As Berger notes, “The idea is to keep sparks contained within the housing, preventing them from igniting volatile substances in the surrounding air.”

Why access control in explosive environments requires specialised equipment

Explosive environments are more common than many people think. It’s not just about oil and gas. “Even in the food industry, a factory producing fine dust could be at risk,” Berger says. “This is where ATEX units really show their value.”

From tracking vehicles at mining sites to managing personnel access in nuclear facilities, the goal is to maintain security while minimising ignition risks. STid’s ATEX range is built to operate safely and reliably under such demanding circumstances.

STid offers a robust suite of ATEX & IECEx certified access readers, designed for both fixed installations and mobile operations. What sets STid apart is its end-to-end control of product development. “We manufacture both the casing and the reader,” Berger emphasises. “So it’s a fully integrated, certified solution.”
