Fitting CCTV is a great deterrent to criminals. It not only improves the chances that they will be caught on camera and identified, but it also limits the range of opportunities they have to commit crime. This is because there are more places than ever across the country covered by a monitoring system.
However, if you are in charge of such a system, and have spent a good deal of money on procuring a CCTV network to protect premises, then you should make sure you have a contract which includes regular maintenance and upgrades. What would be the point of having a camera system if it was not focussing accurately and caught a crime in the act – only it was all out of focus and nobody was identifiable!
Another reason for regular servicing of CCTV systems is to make sure the computer software and hardware is all working properly. Modern systems work by recording on a hard disk logger – just like a standard computer network server. If that hard disk develops an error, or becomes full to capacity with data, then your CCTV system will not be storing the images you may need in the event of a breach of security.
Then there is the more basic level of servicing CCTV systems – simply going out and cleaning the lenses. Cameras can end up very dirty because of pollution and even bird droppings. They should be cleaned on regular occasions to make sure there is nothing obscuring the clarity of the image being stored for future use.
