Speak with visitors at the front door from any phone in the house using the Channel Vision intercom system. This intercom controller lets you monitor two different Channel Vision IU or DP series door units (available separately with a wide range of options) with your telephone. Your phone rings when someone pushes the doorbell, and upon answering it you can communicate with the visitor. If your door unit is hooked up to a
doorstrike relay you can even use the phone to release your door's lock!
The P-0912 doesn't interfere with your telephone's normal functioning and does not require an active phone line for use. If you receive a visitor while on the phone a distinctive call waiting tone will notify you. This device can be wired using your existing doorbell wire or installed with a simple paired wire.
