BID 1000 :
It is a completely passive, perimeter intrusion detection system. It exactly meets the requirements of the defense & the security forces. The sensor cables are buried along the border or across pathways, passes, roads etc. where the detection of an armed intruder is required. There will be no alarms unless the target possesses the minimum alarm requirement. Hence there will be no false alarms due to the movements of animals etc. It provides complete security against intrusion with fully automated monitoring and alarm annunciation system.

PRINCIPLE OF OPERATION

It uses the principle of "Magnetic Anomaly detection (MAD). The sensor loops are buried under the earth. The sensor lops are connected to the microprocessor based field units which are also buried nearby. Data cables are run from the field units to the local alarms and also a central monitoring system. On any armed intrusion, change in the earth's magnetic field results in changes in the currents flowing in the sensor loops. These changes are picked up by the microcessor & sent to the local alarm units and the central monitoring systems as digital data.

Two sensor loops can be connected to each field unit, to provide two zones of detection. Multiple field units can be used in cascade to effectively monitor the complete border. Since the buried sensor cables do not affect the aesthetics of the terrain and due to the invisible nature of the detection field, intruders are completely unaware of the presence of the BID. Therefore it is very difficult to locate, tamper or avoid BID. Add to this the flexibility & advanced capability of the microprocessor based acquisition & control system, BID stands out as the best outdoor sensor system with the lowest vulnerability.

3. Can individually control a field unit without a central controller or PC.
4. It has trigger out puts to switch on lamp's CC-TV cameras, Trip flares, Sirens etc
It has latched or normal (Unlatched) output's. (In latched mode alarm continues until someone acknowledge it)
5. There are additional indicators for the following conditions
a) Low battery
b) Communication failure.
c) arm/Disarm.
d) Cut in sensor loop.
6. Alarm is also generated if the field units are tampered.
7. Special arm/disarm feature makes it possible to trigger electrically detonated 'Claymore Mines' automatically on detection of an intrusion,
