Intercom External Units

External Units
An intercom external unit is a device within an intercom system that allows users to request entry to the building. It allows them to communicate with the person who may grant them passage if that individual desires to.

Then & Now
The commonly used intercom phone, in which only an audio communication sent through intercom panels to the audio intercom receiver, has been available for years.
Now, however, units are capable of relaying the video signal to a video receiver in black and white as well as in color; thus facilitating a formal and complete identification of the person requesting access.

Affordable Progress
You might have a notion that a security monitoring would be very expensive, but surprisingly, the costs have reduced to such a level that it is in fact less expensive to set up a brand new intercom system ,including video applications, than repairing an old audio intercom.
