Audio Video Phone

When a visitor presses the call-bell, a chime is sounded to alert you; and at the press of a button on monitor inside the house, you can see the visitor on the screen. You can then speak to the visitor about the purpose of visit and decide whether to let in the visitor. These is an added facility to install a magnetic lock on the entrance door which can be opened by pressing a button on the monitor key pad.Very useful for ladies and old people who are generally alone at home. Audio-phone is optional. Cordless AVP option also available.
