What Are The Different Types Of Communication Technology Used For Access Control Systems?

There are a few different technologies that access control equipment at your gates and the handsets and gate releases inside the property use to communicate with each other.Before we describe these, here’s a brief outline of what elements comprise gate automation access control systems and what functions they have.

What Does An Access Control System Do?

Access control systems for automatic gates allow visitors to let the homeowners know they wish to enter the property, and the homeowners to allow or deny access.

What Does An Access Control System Comprise?

The components that make up such a system start with the minimum requirement of a buzzer at the gate and a gate release inside the house.The gate buzzer is heard inside the house and the homeowner chooses to ignore it or allow the visitor through the gate using the gate release.If the gates are not visible from the house, an intercom system that allows the visitor to speak to the homeowner would include a call button and speech panel at the gate and a telephone handset and release button inside.

How Do The Components Communicate With Each Other?

In order for someone inside the house to be notified someone is at the gate, then be able to communicate with them and finally open the gate, the gate-side and house systems need to communicate with each other.There are a few ways that this is achieved starting with the simplest technology that is probably the hardest to install.

Wired Intercoms

Wired systems are connected to each other with wires which have to be run from the home intercom handsets to the call module mounted at the gate.This will obviously require laying wires in armoured trunking underground or in conduit along walls outside the property.Wiring inside is easier but needs to be kept neat and tidy and may have to pass through internal and external wallsThe alternatives to wired systems all use a communication technology that is wireless.It should be remembered though, that even without the need for communication wires to the gate-side of the system, power still has to be supplied to the gate intercom.

Radio Intercoms

Radio systems communicate in a similar way to transmitters and receivers used to open and close Gate Automation systems.The control signals and voice and video data are transmitted at specific radio frequencies.As long as there is no interference, this method of communication can be highly effective. In clear space with no buildings or trees or bushes in the way, DECT radio systems can have a range of up to 300-400m

Wi-Fi Intercom Systems

Wi-Fi systems use an existing Wi-Fi network, or one specifically added for intercom communication.In areas where the gate is a long way from the house or the Wi-Fi signal is weak, boosters can be used. However, if the Wi-Fi signal fails, the intercom system will not function.Once connected to the local router via WiFi or ethernet, these systems usually connect on to the internet, allowing communication and gate control via an APP from anywhere in the world that data is available for your mobile device.

GSM Intercoms

he most recent innovations in intercom communication use the same GSM communication used by mobile telephones. With a mobile app, your smartphone replaces the wall-mounted handset and door release inside the home.It allows voice and video communication through the smartphone app as well as gate release.GSM can even be used for communicating with and controlling your gates from anywhere in the world where you have a 3G or 4G signal (depending on the intercom system used).However, as with a failed Wi-Fi signal, GSM intercom systems won’t work if your phone can’t access a GSM network where you are or if there is a break in the GSM signal at the gate end.

Gate Automation Intercoms Comparison

Wired systems provide the highest level of system communication integrity and can be wired considerable distances between the gate and house.Radio signals sent be either the gate calling unit or house handset are usually robust but have a limited range.At Linkcare we provide a wide range of manufacturers’ Access Control Systems, components and accessories.We also provide all customers with free technical, safety and installation telephone support.
