Video Door Phone Intercom Systems can increase your overall safety at home or at your business by allowing you to see who is at the door before you decide to open it or not open it.LightInTheBox has a variety of video intercoms from high end models to more economical ones which produce images in both color and black & white.
A Video Door Phone Intercom System works with camera units mounted outside the entrance door (or designated area) and display monitors installed inside your home (or business) showing what the camera is pointing at. Typically when someone presses the call button on the outside video intercom unit or rings the door bell it activates the camera and alerts the indoor monitor. You can then talk to the person as you look at their image.
Some Video Door Phone Intercom Systems have built-in memory that will record the images of visitors who ring the buzzer. The memory will hold a time and date stamp as well. In addition, some higher end intercoms have a built in open button in which you can lock and unlock your door to allow visitors in.
