The telephone entry system is an intercom system connected to a telephone line; it allows calls to residents of an apartment building, office, or another place that needs to communicate with a closed entrance door with an electric door strike installed.
The telephone entry system will call residents; who will use their phone or cell phone to establish communication and also be able to activate the door strike, which guarantees a safe entry to the property.
Most entry phone systems include an access control; that allows residents of the place either by proximity cards or by keying individual code to operate the door strike and gain access to the building.
The newer entry phone systems have a camera installed inside the panel. Telephone entry systems using IP and SIP technology give plenty of other options; like take photos of the visitor who calls your apartment; record the time and date of the call; receive calls throughout the world, save all this information in the cloud for future reference, and in some recent SIP models it includes facial recognition
