An audio intercom system allows two way audio communication in a closed setting. There are multiple scenarios in which it can be used, not all of them as part of a security setup. They are very useful in commercial environment as well as residential premises for instant contact between people at different points within a particular place. Some of the most common uses are –


•    Keeping a tab on visitors at apartment blocks – A security guard at the entrance will inform the house owner that a visitor wants to come up and meet him. Only after getting clearance will the guard let him in.

•    Audio Intercom systems in individual flats – In many modern apartments there are two-way intercom systems connecting all the flats. Other residents will be instantly warned if there is a break-in in any of them. It acts as an excellent security tool.

•    Communication within large offices – Contact between employees and employer in large offices is absolutely necessary if strict supervision is to be maintained and smooth workflow has to be ensured.

•    Security in large plants and factories - Audio intercom system play a major role in large plants and factories and ensures smooth two way communication between extreme corners of the establishment. Apart from keeping a real time control at any point of time over what is happening in the whole area, any untoward incident can be reported back immediately to the supervisors stationed at any place. Wireless and portable intercom sets are ideal here.
These are case studies only. However, audio intercom system has vast potential in unlimited scenarios.   

Such a system when set up at an entry point leaves the residents safe and secure. The network consists of a call point outside the premises and a phone type device inside. Any visitor will first have to identify himself and if the person inside is satisfied the door will be opened. In certain systems, an attached video camera kept at a vantage point above the entrance enables the person inside to even see who is calling. Other options that can be used in conjunction with an audio intercom system are –

•    keypad where the visitor can punch in a call point entrance code and gain access

•    proxy-reader where a card or tag is swiped to gain entry

•    GSM configuration whereby a door can be operated from a remote location through a smart phone    

Install an audio intercom system in your premises. It will provide a good security setup and peace of mind.
