The basic unit consists of a radio button which is worn / carried by the user while he is in the premises, a microphone, loudspeaker and a sender unit installed at appropriate locations at the user's premises and a data receiver at the crisis management control room.

A touch of the appropriate button (separate buttons provided for security and medical emergencies) in the hand held unit sends out automatically a signal to a Control Unit inside the premises.

The unique codes sent out by the hand held unit are received by the Control unit which in turn are relayed automatically through an auto dialer to the data receiver at the Central crisis management center. The system attempts to provide response when it is most critically needed.

Normally, the response team reaches within minutes & are usually armed to face any situation, including armed intruders. Though there aren't many agencies offering such a service in India but a similar concept can be implemented with private security guards in a Apartment complex or housing colonies.
