CCTV Systems Do More Than Protect Against Shoplifters


By Ben Sparks

Ever since the advent of small affordable CCTV systems, protection of property has been a paramount use. Originally most of the CCTV systems were located indoors and utilized as a deterrent against shoplifters. As CCTV systems, particularly cameras have become smaller and more inexpensive, the CCTV cameras have moved outdoors and now provide property owners an added measure of security in protecting their property.

It is difficult today to enter any store and not see at least one CCTV camera that is part of a CCTV system present. What many people don't realize is that CCTV cameras are also present outdoors also. These cameras provide 24 hour surveillance of gas pumps, store parking lots, entrances and perimeters to plants and warehouses and the lobbies of public buildings. These outdoor cameras provide physical property protection for the building owners.

CCTV cameras that are outdoors can often be recognized. The housing that holds the camera may be the size of a loaf of bread. Alternatively the housing can be a dome that is smoked glass or glazed silver or gold. These dome housings hang like pendants from walls and light poles. The cameras that are in the domes are often mounted to pan/tilt heads and equipped with telephoto zoom lenses. These devices permit the camera to scan the entire area around the camera and are not fixed to a single location. Should trespass be viewed by the operator, the pan/tilt head can be stopped in the location of the trespass, the camera zoomed in to the trespasser and the movements of that person followed with the pan/tilt function controlled manually. This ability allows one camera to do the function of several cameras thus reducing the overall cost of the CCTV system while increasing its effectiveness.

CCTV camera housings are often subjects of vandalism or outright destruction. Vandals attempt to damage the camera and housing. Trespassers who are intent on robbery try to disable them to deny the security personnel the opportunity to intervene in the robbery. To combat this several manufacturers provide ballistic rated housings. These housings are built to absorb and withstand a bullet fired from a gun and continue working, providing the images of the area that they are trained on. While these housings are more expensive initially cameras that are located in vandal prevalent areas that have ballistic rated housings do not have to be replaced as often as those in non ballistic rated housings.

The utilization of security cameras to secure physical property, warehouses, truck parking areas, plants and parking lots provides the owner of the property the assurance that the property is always being looked after. The property owner does not have to pay a security staff to patrol the premises. This reduction in staff will pay for itself in a short time thus increasing the profit margin of the company. Additional savings may arise from a lowered insurance rate due to the CCTV system that is in place.

In the past, CCTV systems needed a human operator on site to monitor the CCTV system. The availability of the Internet has changed that. Fixed cameras equipped with motion detection can transmit video signals to a remote central station through the Internet. This ability allows the operator at the central station to view the intruder and notify the local law enforcement authorities. CCTV systems still protect the store owner against shoplifting. The advent of small efficient cameras and the ability to transmit video to central stations permits the exterior of a facility protection without the cost of security staff. These attributes of a CCTV system provide an effective cost saving to the property owner.
