Intercom Based
Integrated audio, video or telephone based door-entry systems enable you to monitor and control visitor access into any premises – a door entry system can be interfaced to work with gates / barrier automation and other associated access control systems.
Systems can range from the simple one way analogue telephone entry, typically seen on residential and small commercial buildings comprising of a door panel, lock release and handset, to the far more sophisticated digital systems including Multi-way Video and audio systems or remote access systems used for large commercial premises or blocks of apartments.
Audio Entry Intercom Systems
Audio Entry Systems provide audio communication between the protected and unprotected side of an entrance, allowing you to verify the identity of a caller before granting access. Access is usually achieved by triggering a lock release or similar locking mechanism by simply pushing a button located on the receiving handset. This type of system would normally incorporate a door station and an internal phone style handset.
Video Entry Intercom Systems
The video door entry system is the same as the audio door entry system but includes the added benefit of providing live video at the door station. The video telephone allows the resident to view callers at the entrance, speak with them and then grant access, which would be achieved by triggering a lock release or similar locking mechanism on the telephone handset. This system would be the same as that used for the Audio system but will include a small camera built in to the door station and a small 4” monitor in the telephone handset.
Telephone Based Intercom Systems
Some larger sites, especially those which are monitored from a central station, would utilise a telephone based entry system. These systems would usually be installed in conjunction with other security products, but can also form part of a stand-alone system. These systems would be linked to a standard telephone line or PABX system, when the button is pressed the unit will dial a pre-programmed number. Upon answering the phone, audible communication can be held between the door station and telephone. Access can then be granted by pressing a pre-programmed button on the telephone handset. This type of system could be used for commercial properties requiring controlled access for out of hour’s deliveries.
GB Alarms can design and install complete systems for offices, industrial premises and apartment blocks where secure control is required. Any of the systems described can be tailored to exact requirements from small stand-alone systems to fully integrated systems.
