Door entry systems provide the perfect safety solution and, for businesses, easy compliance with the Disability Discrimination Act. Intercom technology has come a long way since the very first audio systems with a panel at the front door and entrance handset which 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. In the following phase, the dedicated handsets weren’t required 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 the number of a flat, the panel speed-dials the homeowners’ phone number and connects the visitor at the panel. They then grant the visitor access, in most instances by pressing the zero on the keypad of the phone. 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 different systems, the homeowner doesn’t require the traditional key. They may either be issued with a key fob/card or even coded access. This emits a signal that also provides access. A significant benefit of this is that you will not have to change the lock when the card/fob is lost as you would have to when the traditional 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.
Overwhelmed by the Complexity of Security? This May Help
The system may work as well when used in a business environment. The entrance panel connects to the PABX switchboard and dials whatever extension has been set automatically. This can be altered easily to fit using simple software. Consequently, if the receptionist has gone for lunch, then the entry calls may be redirected to another phone. Where no BT mobile is available; a GSM system will connect to a mobile phone for complete flexibility.
