The SVDC 2-Way Door Com combines a 200 degrees door viewer and a 2-way intercom providing an excellent way of identifying person/s outside the front door. It was specifically designed to help reduce the increase in Bogus Calling and Distraction Burglary as you can talk and listen to the caller without opening the door.

The SVDC installation process is exactly the same as installing a normal Door Viewer (drilling one hole). 

With this product there will be no need to open the door until you are fully confident who is outside the door.
