Car Yard Security
WATSON HOLDEN : MELBOURNE
Watson Holden is one of the premier Holden dealerships in Victoria and at any time has new vehicles worth in excess of AUS$8m on site.
In spite of electronic surveillance thieves repeatedly raided the site, the expensive Mag wheels and high performance tyres of the HSV models being the most common target. Further more the raids often caused external damage to the vehicles.
In March 2003 an integrated security system was designed for the site where any alarm from an outer electric security fence was interfaced with lights, CCTV cameras, sirens, and loud speakers through which warnings from the monitoring station could be broadcast.
Within days of completion the fence was cut but the raid was aborted as the system activated. Another four raids were repelled without loss before the gang were finally apprehended by the police.
The security system has worked well for Watson Holden and other dealers in Victoria are now following their example.
Residential Estate Security
Violent crime in the many cities around the world has led to the development of residential estates built within the secure confines of substantial physical barriers topped with electric security fencing systems monitored 24 hours a day by the on-site security guards.
This example from South Africa has a 5 km perimeter with a nine wire walltop electric fence organised into six sectors. Each sector is powered and monitored by an energizer monitor unit linked by radio to the security guard house.
The fence system is also linked to CCTV cameras and in the guard house a graphic display and local alarm immediately guides the security guards to the location of any attempted intrusion on the perimeter.
