INTERCOM SYSTEMS

An intercom system is a stand-alone two-way communication system which is used to transmit and receive audio/video signals. It is an essential part for residential and commercial security which helps in the identification of visitors. This communication device can be used in vehicles, buildings and can also be used for brief conversations or to check the visitors at the front door of your home. It can also be used for security purposes, like to provide voice communication between two or more locations.

A simple intercom system comprises of a Master station and a Substation. The substation is located outside the home or building and the Main station is located inside where the communication is to be received. Intercoms system can be connected to loudspeaker systems, telephones, and to other intercom systems. Door intercom systems are used to talk to the visitor at the front door. Addition of a camera to the intercom system helps you to see the person as well.

The usage of intercom systems is not limited. It can be of great use in the health industry or in hospitals and ensure the safety and security of patients, staff and visitors.

Voice Intercom Systems

A voice intercom system is a typical two-way communication device which is used at homes and building to check the visitors or used for security purposes. A simple voice intercom system has a Master station and a Substation. To contact the master station from the substation, there a call button which has to be pressed and then the master station responds. For the master station to contact the substation, the talk button as to be pressed and the user can then speak to the microphone. Release the talk button to hear from the substation.
