Door entry systems can serve single dwellings or apartment blocks. They instil confidence in the residents as they can clearly identify visitors, by either an audio only system or a video system. Door entry systems can be interfaced with access control systems with a proximity reader installed on the door entry panel: residents use a fob to gain access.

Door entry systems are a brilliant way to improve security in large houses, offices and residential blocks. Everyone will feel the benefit of a professionally installed door entry or access control system.

Where cabling is difficult or impossible to fit, various wireless door entry systems can be installed, including PSTN (public switched telephone network) or GSM (global system for mobile communications) These are popular options in historic, finished and listed buildings where there may be space, planning or conservation constraints to consider.
