Radio Remote Control
This is a relatively simple and effective way of achieving access control for power operated gates, typically using battery powered hand-held devices, such as key-fobs or larger units.
Using approved VHF radio frequencies, a radio-controlled device can work over a distance of between 20 and 1000 metres. Radio remote controls provide an ideal solution for multiple users to control power operated gates.
Proximity Detectors
Proximity detectors mounted on powered gates which can pick up a signal from a transmitter (for example on a vehicle) can be suitable for use within the confines of premises, and therefore accessed by trained staff only - e.g. a forklift and driver passing from one distinct area to another within a large industrial complex.

Number Plate Recognition
As the name suggests, this system will recognise specific number plates that have been programmed into software on the control system. A number plate recognition system for automatic gates would normally be part of a wider access control system - e.g. it would also have a local or remote push button system for security staff to open the gate for un-registered site visitors.
Digital Keypad

Digital keypads are an ideal solution for both pedestrian and vehicle access, and simply work when a pre-determined code is keyed-in. These can be programmed to allow full-site access or restricted to certain areas only. Typically, a keypad system would also have an override such as remote push button for security staff in a separate location or adjacent control room. The digital keypad can be made vandal proof through use of a high quality stainless steel construction.
Magnetic Card Reader
Similar in appication to the digital keypad, magnetic card readers allow for a slightly quicker entry as the sliding gate will open when the pre-issued card is help up against the reader. Due to its relative simplicity and speed of use, this system is ideal when large numbers of people and/or vehicles need access to a site via an automated gate. Alternatively, selected personnel could be issued with cards to allow them to operate the gate for others - e.g. site visitors

Induction Loop
This system uses a cable loop (underneath the road surface) which produces a magnetic field. The magnetic field changes when a vehicle passes over it, activating a signal which opens the powered gate. The system can be designed to work with vans, HGVs and cars. Induction loops will usually be used for vehicles exiting a site rather than entering.
Local or Remote Push Button

Local or Remote Push Button

A local or remote push button provides a simple means to operate the automatic gate where an entrance is manned. As mentioned with some of the other more sophisticated options, a local or remote push button is often used in conjunction with other systems. Push button controls should be designed so they need to be held down to run. This also allows other systems to be overridden when necessary.
Key Switch
A high security solution, which means selected personnel having to insert a key in order to activate a local or remote push button.
Audio and/or CCTV Remote Control
 |
Audio and/or CCTV Remote Control
|
This system would typically be used where control of the automated gate was in a remote location, and in conjunction with the above push button system. So when a person or vehicle approaches the gate, security personnel can establish whether or not to allow access by using audio and/or the video obtained via CCTV.
