Hgs [india] ltd supplies security surveillance system, which has been manufactured and designed for the secure protection of perimeters against intrusion, especially in remote locations. The security system is not only very sensitive but also extremely reliable. The security surveillance system is best suited to those areas where a large perimeter needs to be monitored and an automatic alarm system is essential. For being passive, the system does not operate depending on regular power. Being designed on the principle of monitoring of seismic or ground vibrations, the system comes at a price much lower than the price of other competing systems, which use other technologies for intrusion detection. The security system has been particularly designed for border areas, industrial sites, large or valuable store dumps, warehouses, explosive magazines, nuclear installations, oil refineries, power stations, prisons, army bases, and farm houses. The seismic sensors in the system are installed on multicore cable, which is concealed in a customly designed trench along the perimeter. Its ground electronics has been tailor-made to provide maximum sensitivity to prevent the incidence of false alarms or insufficient detection. The system`s each control module contains 16 channels, with each channel corresponding to a specific length of the perimeter and this zone can be as small as 5 metres or as large as 200 metres. At the time of intrusion, the surveillance unit triggers an audible and visual alarm by displaying the affected zone. Besides this, the control unit can also trigger floodlights, sirens, or closed circuit tvs in the affected zone. The security surveillance system offers a gain control to regulate ground monitoring sensitivity in areas where background noise fluctuates significantly in a twenty-four hour period. As a result it provides the system high versatility and flexibility with user adjustable trigger levels when required for specific locations.
