Intercom systems can be a very useful tool for the home or the workplace. Being completely separate from the telephone system units can be set up to communicate between two or more separate areas of a building complex.

Intercom systems can be integrated into Access Control & Door entry systems, providing communication between casual visitors and the occupants prior to entry being granted.

Within the home, Intercom systems can be used to identify callers before entry is granted, an excellent way of preventing doorstep crime. Intercom systems can also be of benefit within larger family dwellings, where family members may wish to communicate for instance between the home office and the living area.

Intercom systems may be audio only or audio/video.
