CCTV - the Basics
Video surveillance
It is surprising how many companies consider losses from burglary or break-ins as a fixed element of their cost calculations. While such considerations are a legitimate concern, they always leave a bitter after-taste. Providing CCTV surveillance for these critical areas is an effective solution. It means that retail premises, warehouses, staff entrances, accesses to bank safes, ATM areas and research facilities can all be placed under discreet surveillance with little in the way of personnel expenditure.
With CCTV you can obtain reliable recordings of any irregularities. It also helps to dissuade potential criminals. CCTV also opens up a number of interesting possibilities in the production sector. The system is an efficient way of monitoring manufacturing processes. Any malfunctions are spotted in a matter of seconds and automatically signalled to the surveillance control centre. More and more private individuals are also using video surveillance to protect their property or premises against intrusion. Securiton has a wide range of complete security packages available at attractive terms for such applications.
Image recording
Good image quality depends on all the components, from source to image storage, being adapted to each application. One particularly crucial link in this chain of image recording is the camera. It is the source of the video signal, and the end result can never be better than the source itself. To guarantee faultless operation and recording the cameras must provide a perfect image even under difficult lighting conditions.
Image storage
Modern security technology would be inconceivable without digital image storage devices. While time-lapse recorders were still in use only a few years ago, today’s digital image recording provides functions and operating concepts which greatly facilitate the work involved.
Coding
ncoders are needed to transmit video images via a network or to preprocess them for digital image storage. Today’s encoders offer outstanding image quality, a multitude of inputs and outputs, and transparent protocol transmission.
Video analysis
There has been a sharp market increase in intelligent video analysis thanks to modern algorithms and high-performance processors; indeed, in years to come, video analysis is set to spread to areas which had previously seemed unthinkable.
While human operators are more skilled at interpreting individual images reliably and drawing conclusions with regard to an intervention based on a given scene, intelligent video analysis systems are designed in principle to respond swiftly to any changes within individual images.
And when it comes to analysing the image material from several cameras simultaneously, intelligent video analysis is in most cases better suited than human observers.
