The powerful sound waves generated by the transducers of the repellers are within the hearing range of many pests, and cause them pain and discomfort. Sometimes, the pests will leave the area being protected immediately, and at other times it will take as long as 4 to 6 weeks before there is a significant reduction in infestation.

CCTV (closed-circuit television) is a TV system in which signals are not publicly distributed but are monitored, primarily for surveillance and security purposes. CCTV relies on strategic placement of cameras, and observation of the camera's input on monitors somewhere. Because the cameras communicate with monitors and/or video recorders across private coaxial cable runs or wireless communication links, they gain the designation "closed-circuit" to indicate that access to their content is limited by design only to those able to see it.

Public Address System: (PA system) is an electronic sound amplification and distribution system with a microphone, amplifier and loudspeakers, used to allow a person to address a large public, for example for announcements of movements at large and noisy air and rail terminals or at a sports stadium.

LISTEC LHS Cable- Heat Sensing Cable: System Concept - The List sensor cable is a resettable type fire detection system. The microprocessor based sensor element is completely encapsulated in the heat sensing cable to protect sensors from environmental influences. Sensor element detect both fixed temperature as well as rate of rise of temperature. The sensor elements pin point the location of fire or temperature monitoring via individual address. The sensor cable is primarily used for fire/ temperature detection in very harsh & dusty environment for indoor as well outdoor applications.

Typical application of sensor cable are:

Cable trays / tunnels
Conveyor Belts
Cable Galleries / Treys
Road / Rail Tunnels
Car Parking Areas
Cold Storages
Hazardous Areas

Access Control System is the selective restriction of access to a place or other resource. The act of accessing may mean consuming, entering, or using. Permission to access a resource is called authorization.

Water leak detection is an expression more commonly used for larger, integrated systems installed in modern buildings or those containing valuable artifacts, materials or other critical assets where early notification of a potentially damaging leak would be beneficial.
