News Flash-April 2013
After the first real winter storm pushed through Cape Town earlier this week, bringing with it strong winds and heavy rains, we were inundated with alarm signals from clients that were experiencing an unusually high number of alarm activations. CBAR would just to like to advise that the predominate wind direction in the summer months is from the South East and the rain bearing winds in winter are from the North West.
Please ensure that all outside foliage is trimmed to accommodate the change in wind direction, which could now move foliage disrupting outdoor sensors and beams.
For those clients who do not have any outdoor detection, CBAR carries the full range of outdoor beams and sensors and would be glad to provide you with a free quotation should you wish to upgrade your electronic security.
On a more serious note, over the past 10 days, there has been quite an increase in the number of businesses that have been broken into. It appears that in particular, clothing and other retail stores are being targeted in and around the Kloof Street area.
The modus operandi seems to be that the intruders are aware as to how a standard motion sensor works and choose an entry point in an area obscured by store contents. In other words where the PIR cannot see. Most retail stores have shelving and rails with carrying stock, that diminishes the effectiveness of an infrared sensor, as a sensor cannot see through objects. Also part of the modus operandi is that the intruders crawl around flat on the floor between shelving or rails and pull the items down without triggering the alarm.
Two solutions to this are to have 360 degree ceiling mount PIR’s installed in central areas overlooking shelving and stands. This will then trigger the alarm system as they provide a 360 degree coverage of an area from directly above, as apposed to a corner mounted PIR. Furthermore glass trap shock sensors can also be fitted to window panes as well as digital glass break detectors, which activate on the sound of breaking glass.
Again, should you require advise on these detection devises please do not hesitate to contact our offices on 0860 151515.
A safe and pleasant weekend to all.
