Video doorbell 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. There are many stores on line or else where have a variety of video doorbell from high end models to more economical ones which produce images in both color and black and white.
A video doorbell system works with a camera unit mounted outside the entrance door (or designated area) and a display monitor 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 doorbell units 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 vedio doorbell has a built in open button in which you can lock and unlock your door to allow visitors in.
The lower priced video doorbells are usually black and white and come with basic features. While the higher priced video doorbells are colored and incorporate the features of a surveillance system with built-in infrared lights that will allow you to see your guests at night. Some systems might even have a manual turn on function in case your visitor knocks rather than rings the door bell.
