CCTV
- Fully professional equipment at a reasonable price
- Bespoke system design to your precise needs

Crisdan Security CCTV systems can include features such as low light cameras, producing
high resolution colour images during the daytime, switching to monochrome at night.
Cameras are connected to digital recording devices with any number of cameras downloading
to a single high capacity hard drive. Selected sequences can be easily recorded
onto CD ROM.
Live feeds can be transmitted to a Euro Standard Monitoring Centre for transmission
to desired locations via Broadband or ISDN.
CCTV Systems require very specific expertise. Our engineers are fully trained specifically
in the design, installation and maintenance of CCTV systems. You can rest assured
your system will be operating at full efficiency at the vital time.
CCTV systems have been a very useful tool in helping to combat burglaries and theft
of motor vehicle from front driveways.
The most basic system is to have an external camera to view the front of the property
and cabled into the domestic TV. The camera will be programmed into a spare TV channel,
the occupier will be able to view what is in range of the camera.
CCTV Digital Recording
The advances in digital recording have almost made tape recording systems redundant.
Crisdan Security are currently installing many domestic CCTV systems with up to
four cameras around detached properties, linked back to a digital recorder. The
hard drive on the recorder can store images up to one month, but a more realistic
recording time would be about one week for a reasonable quality image and time lapse.
A small 10ins monitor is usually installed beside the recorder, which enables the
user to play back and view. If a permanent record is required this is achieved by
inserting a CD disk and recording the desired incident from whichever camera.
Infra Red night cameras
Most thefts of vehicles and neighbourly disputes resulting in criminal damage occur
during the hours of darkness. There must be some light for the video to function.
Recent advances in infra red technology have allowed external unobtrusive cameras
to be fitted with infra red LED's. This allows good quality monochrome cameras to
see in the dark for a distance of up to 25 metres.
Crisdan Security can also install day/night cameras. This type of camera can view
and record in Colour during the daytime, but when the ambient light level drops,
the camera automatically switches to monochrome (black/white) for sharper images.
