When you have an UNKNOWN VISITOR, who is standing outside your door/gate in a DIM LIGHT, do you think it is safe to OPEN THE DOOR?
Do you have to WALK UP & DOWN too often to open your main door for visitors and you get tired? Do you want to do it REMOTELY and conveniently?
DON'T TAKE RISKS. Now, using appropriate devices, you can CLEARLY SEE and TALK with the visitor, without opening the door and decide whether you should open the door/ gate or NOT. You can also open the door "remotely" by pressing a "door open" button on the video-phone.
HOW CAN I SEE ?
The camera in the outdoor panel of the Video Door phone can "see" the visitor. If infra-red light is used, it can "see" even in darkness. This picture is shown to you on the small TV-like display screen on the video-phone near you inside the premises, as soon as the door call-bell on the outdoor panel is pressed by the visitor. You can also press the "monitor" button on the video-phone anytime to see the view in front of the camera.
HOW CAN I TALK ?
Two way communication enables you to talk to the visitor from the handset (or Handsfree in some models) of the video-phone.
HOW CAN I OPEN THE DOOR REMOTELY?
When you press the "door open" button on the video-phone after you have confirmed the identity of the visitor, a relay-switch in the outdoor panel operates to open the ELECTRONIC DOOR LOCK and lets the visitor in. The door shuts behind the visitor automatically by use of an "auto-door-shutter".
VDP systems are available in colour. B/W models, although available still, are going out of fashion. Some models are shown below:
