Intruders have no chance with a MicroPoint Cable perimeter 


Safety-savvy property owners understand the importance of having an effective first line of defence capable of keeping criminals off their premises.


But, says Valerie Bingham, Product Manager for Elvey Security Technologies, there’s often a big gap between a consumer’s understanding of the importance of perimeter protection and knowing what will work – especially if the property is large.


“Many perimeter protection devices will sound an alarm if an intruder is detected, but if that area is kilometres long, security personnel won’t be able to ascertain upfront where the intrusion has taken place,” she says.  “This means that the intruder could be well hidden somewhere on the property by the time the area of entry has been discovered, which obviously has serious security implications.”


In crime-ravaged South Africa, where the need for good perimeter security is paramount, Ms Bingham cautions against a one-size-fits-all solution, saying that some perimeter applications require specific and unique intrusion detection solutions.  “When it comes to challenging sites such as utility plants, railways, military bases, correctional institutions, mines and factories, the most effective perimeter security solution is one that will not only deter trespassers but will also allow security personnel to identify the precise location of an alarm,” she explains.  


For Ms Bingham, one of the most impressive products on the market today is Southwest Microwave’s MicroPoint Cable Perimeter Intrusion Detection systems.  “This sophisticated perimeter security system is ideal for monitoring and protecting large areas of open space,” she says about the cable system, which was first introduced in 1998 and recently celebrated a milestone achievement of having installed more than 2.1 million meters of perimeter fencing protection worldwide.  “One of its most appealing features is its ability to eliminate false alarms, a highly irritating problem that plagues most other fence sensors.”


Technically-minded prospective end users will be interested to know that MicroPoint is a volumetric, terrain-following sensor able to reliably detect and precisely locate walking, running or crawling intruders along the perimeter, adds Zane Greeff, Technical Director for Elvey Security Technologies.  “This makes it the number one choice for applications that require covert perimeter protection.”


Explaining further, he says the cable technology can detect any fence disturbance and narrow it down to within 3m.  This it does through the use of proprietary digital signal processing (DSP) algorithms, which can pick up any attempt to cut or climb the fence while ignoring noise from wind, rain and heavy vehicles.


What’s more, the MicroPoint Cable also transmits alarm signals and operating power to all modules and auxiliary sensors along the perimeter, which eliminates the need for extra wiring.  “The software interfaces directly with a personal computer which becomes the alarm monitoring display and graphic map,” he points out.  “The result is a system that not only provides unparalleled performance but also measurable cost savings.”
