The E-50 Series Video Entry phones are compact, weather and vandal resistant speaker phones designed to provide two-way handsfree audio communication and color composite video of who is at your door or gate. The E-50's compact size allows it to be mounted in a standard single gang electrical box. The E-50 is available in five different attractive finishes to match your door hardware, light fixtures, etc. Replacement E-50 faceplates (PNL50) can be purchased separately and are available in all five standard finishes.

The E-50 entry phones can also be connected to an unused analog station port (programmed for ring down) on a phone system or connected directly to a telephone line when used with a Viking model K-1900-5 auto dialer.
