Perimeter detection works as an alarm that is triggered when an intruder invades the perimeter of the protected area by the installed system.
These systems are highly effective for large outdoor areas that are difficult to cover with physical security (guards).
In addition, one of the most outstanding advantages of this alarm system is that it is activated when the intruder is at the very limit of the property (perimeter detection).
Let’s see some systems with their advantages and disadvantages:
Infrared Barriers: It consists of two parts, one transmitter and one receiver. There are 2, 4 and 6 beams (diffuse) and from 5m to 300m. There are also wired or wireless, and you can put 2 more in series one on top of the other.
It is important to camouflage them inside tubes so that the intruder familiar with this system does not see that a Security Walton-on-Thames system is installed.
The wired model is inexpensive, but its installation requires trenches, and the cable must be very firm so that false alarms do not occur. The wireless model has a high cost, and it also requires high technology for the system to run on batteries. On the other hand, the wireless barrier does not differentiate between people and animals and for an area with pets, false alarms would be generated.
Outdoor Movement Sensors: They work by detecting the infrared energy emitted by the bodies or by their movement. The signal can be transmitted either wired or wireless (with battery).
Microphone Cable
It is a cable that is activated when it has contact with blows, cuts or vibrations. It acts as a microphone that sends sound to a center in the form of an electrical impulse. We recommend zoning the protected area by areas of maximum 150m, to be able to tour the area efficiently in the event of an intruder being detected.
