Door entry systems offer both the ideal security solution and, for companies, simple compliance with the Disability Discrimination Act. Intercom technology has come a long way since the original audio systems using a panel in the front door and entrance handset which was committed to buzz you in. Initially, video has been added so that the callers could be examined. After the black and white color versions, the digital signals replaced analog signals. At the next phase, the dedicated handsets were not needed anymore. The call panel found at the gate was connected to a switchboard or telephone. This kind is one of the more intricate door entry systems currently offered. It is quite popular with those charged with maintaining apartment blocks or landlords.
When a visitor presses a flat number, the panel speed-dials the homeowners’ phone number and connects the one visiting at the panel. They then grant the visitor access, in most cases by pressing the zero on the telephone keypad. Some models include video that may be viewed on particular TV channels in the flat, adding another layer of security for more peace of mind.
With various systems, the homeowner does not need the traditional key. They could either be provided with a crucial fob/card or even coded access. This emits a signal that also provides access. A vital benefit of this is that you will not have to change the lock if the card/fob is misplaced and as you would have to if the normal key went missing. The card/fob may be instantly deleted from the system and a new one added and given to the resident. The system software also empowers the phone numbers to be altered as needed, so there are even more advantages.
The machine can work equally well when employed in a business environment. The entry panel connects to the PABX switchboard and dials whatever extension has been set automatically. This can be modified easily to fit using simple software. Therefore, if the receptionist has gone for lunch, the entry calls may be diverted to a different phone. Where no BT mobile is there; a GSM system will connect to your mobile device for complete flexibility.

The most recent development is a door entry system that works via an online connection via an IP tablet or phone, PC or notebook. This means that distance to the property manager or security is never an issue and one individual can supply or restrict access and administrator control that is programming users, changing door status or deleting interrogating, to sites or a number where that is needed.
