CCTV Glare
For CCTV to play its fullest part in a home security system, it needs to be fully operational during the day and
the night.
Therefore, during the hours of darkness, it needs an adequate amount of lighting in the area under
surveillance.
There is little point in having a video recording of an attempted intrusion, when the images on the video
recording are too dark to make out properly. Lighting is really important to get the best out of your cctv
installation.
One problem that can be encountered when installing lighting for a camera based surveillance system, is that of
cctv glare. This comes about when there is too much contrast between the light and dark areas in the cctv camera's
range of vision.
This could be from light reflecting off a surface and creating glare for the camera. It could also be from
incorrectly angled lighting that either in part, or completely, shines at the camera and 'blinds' it. CCTV glare
could also come from an open lighted window
In some installations it may be prudent to have lighting permanently switched on during the hours of darkness.
More generally, lighting would be activated through motion detectors or sensors in the surveillance area.
The cctv lighting needs to:
- Illuminate fully and evenly, the area being monitored
- Be securely located so that it cannot be tampered with by anyone
- Be positioned so as not to aim direct light at the camera lens, nor to create reflected light which could
create cctv glare
- Avoid becoming intrusive to owners of neighboring properties.
Where professional cctv systems are being installed, special filters might be added to the camera to ensure that
light is evenly distributed, making video footage more presentable.
Lighting and cctv glare are not an issue where infra red cameras are being deployed,
CCTV Lens Repair
The quality of images being produced in a CCTV system will depend in large part on the quality of the camera
lens. CCTV lens repair is essential if it becomes damaged or dirty in normal operations.
The quality of the lens plays an important part in the overall performance of the camera. It enables it to
reproduce images in high definition, thereby enhancing the quality of surveillance.
