To get a preview of who is knocking at your door without actually opening it, you can use a door peephole or consider a wireless video intercom that allows you to view and talk to a visitor from inside your home from an indoor monitor. This is a comfort and convenience if you're disabled or working in the house at a distance from the door.
A video monitoring system is made of two components, an outdoor speaker/camera and an indoor monitor. The indoor monitor rings and displays a picture of the visitor on the screen when the visitor presses the button on the door unit. To install a wireless video monitoring system a security company will charge $410, which includes labor and the material. If you're handy, you can buy the system and install it for $295 and save 28 percent. In addition, you'll need four connectors and wire to connect the camera and monitor together.
