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 first audio systems with a panel at the front door and entry handset that was dedicated to buzz you in. in the beginning, video was added so that the callers would be scrutinized. After the white and black color models, the electronic signs replaced analog signals. At the next phase, the dedicated handsets were not needed anymore. The call panel located at the gate was connected to a switchboard or phone. This kind is one of the more complex door entry systems now available. 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 phone number of the homeowner and connects the sole person visiting at the panel. They then grant the visitor access, most times by pressing the zero on the phone keypad. Some versions include video that might be viewed on specific TV channels in the apartment, adding another layer of security for additional peace of mind.
With various systems, the homeowner does not need the traditional key. They may be given a key 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 might be immediately deleted from the machine and a new one added and given to the homeowner. The system software also enables the phone numbers to be changed as needed, so there are even more advantages.
