What can you do if something happens outside of the field of view of your CCTV? You know when a car was broken into in your car park or something was stolen from your office, but your cameras didn’t pick it up. What can you do?
There is a new camera technology that has entered the commercial CCTV installers tool box. This is called a Fisheye camera; the Fisheye camera can get a 360 Degree all-round view.Now you have visibility on everything that happens. Now what?
Let’s look at a few rules and recommendations to ensure your CCTV is both a deterrent and a great source of evidence:
- Mount Fisheye cameras on the ceiling so that you make maximum use of its coverage. If you mount it on a wall, much of the image will simply be the ceiling.
- Use traditional cameras to cover entrances and exits. Fisheye cameras will show the sequence of events, but lose some resolution when the image is de-warped to be viewed.
- Match the manufacturer’s camera to the recording hardware. This way the software can de-warp the images and give you a virtual PTZ (pan tilt zoom) on the recorded data; it’s like going backwards in time and controlling the camera to follow the users’ activity.
- A camera with built-in infra-red illumination will allow for night time viewing; a key time for crime.
- Consider whether motion detection, line crossing or heat-mapping may be useful for you as well.
- Always adhere to the Data Protection requirements.
- Get high quality large images of people entering so that they can be identified.
- Review both the day and night recorded images on a regular basis.
- Check your recordings go back long enough to cover your requirements.
- Make sure all cables are protected and not easily accessible.
CCTV cameras can be a great deterrent but only if you have full coverage of the space. Traditionally that will have meant a large number of cameras. Now a combination of Fisheye and traditional cameras can deliver the deterrent you desire and the evidence you need – all at a much more sensible cost, but you do need to follow the rules.
