India faces several military and non-military threats to its national security. While there are threats from its neighbours, it is mainly the threat from terrorism and ethnic insurgency, which is ever growing due to external support. A well designed system provides in-depth protection with multiple layers of security that will need to be penetrated in sequence by the adversary, minimizes the consequences of single component failure, and exhibits balanced protection no matter which path of attack the adversary chooses. Protection can be obtained through various combinations of technology [hardware and software], manpower, and procedures. Tata honeywell`s systems experts build the system using any of the popular industry standards such as the latest intel pentium processors, the latest microsoft windows or unix operating systems, and databases such as sql server. They design and implement effective systems for the broadest range of security applications: video surveillance, perimeter surveillance, border surveillance, intrusion detection, access monitoring and control, vehicle and cargo tracking, organic and inorganic detection, meteorological monitoring, fire detection and alarm.
