Want to see who is knocking at your door without actually going to the door and opening it? A lot of people do, and one way is to install a wireless video intercom that allows you to view and talk to a visitor from an indoor monitor. If you're in the back of the house or on another level or disabled, it's a convenience and comfort to see who's at your front door without having to go there.
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. Use wire nuts to connect the outdoor video/doorbell unit to the existing doorbell wires.
乐动体育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.
