Look who’s at the door

Gone are peepholes to identify your visitor, VDP is here to stay
|
You no longer have to peep through the doors to see who has come home. Video door phones (VDP) help residents identify visitors, authenticating their entry or occasionally, shooing pesky salesman away. The VDPs come with a bell switch and are categorised into two variants — colour or black and white. One has the option of selecting hands free and a handset console that comes with a four to five inch screen which is connected to the bell switch
.
A camera with a ‘fish eye’ lens is fixed on the bell switch console in addition to a speaker and a microphone for a two-way conversation. The camera is activated as the calling key is pressed and a visual of the visitor appears on the screen of the VDP which keeps on beeping until one picks up the receiver or activates the talk option.
Visibility
The cameras have LEDs around them to increase visibility during night, a pick from the latest web cameras that work on the principle of light sensitivity.
Many apartments are equipped with a video door phone as builders have included it as part of the deal. “This is the best and safest way to know who’s on the other side of the door. The set-up is user-friendly,” says K. Shashank, Business Director of e-Zone securities.
Those at apartments are placed at the entrance and have calling buttons alongside flat numbers, enabling residents to talk to visitors.
Another interesting feature is the ‘door unlocking system.’ The console is connected to an electro-mechanical lock, which can be opened by the ‘unlock’ option. One can have the console installed in the bedroom and can unlock the door by pressing a button in case a family member or a friend rings the bell.
Vandal proof
Some of the bell switches are vandal proof. An alloy metal is used for casing the bell switch where the camera, microphone and speaker are hidden except for the calling button.
“Many established brands such as Godrej, e-Zone and the latest entrant, Zicom, make these video door phones that are priced between Rs.5,000 and Rs.7,500 for black and white and Rs.12,000 to Rs.15,000 for those with colour screens.
