That video can go to your smartphone, computer, or to a screen inside your home. Doorbell cameras are part of many home automated systems and provide an extra layer of protection. These cameras often come with two way talk, night vision, and a built in motion sensor. As with any security camera, check out the video resolution and field of view. When wireless doorbell cameras activate, the person outside your home will have no idea whether you are on the other side of the door or on the other side of the world. Door and window sensors are contact motion sensors that trigger an alarm when the protected door or window opens.
