CCTV equipment should have a matching specification between the cameras and the recording digital video recorder ( DVR)
If the CCTV equipment matches the recorded images should be very close to the live images in quality.
The majority of installations required that the recordings are visible during darkness and there are two basic types of camera, LED cameras and a better quality night vision cameras.
For example a night vision camera which is high resolution (680 TVL) with a full menu to match the installation requirements, recording at 25 frames per second in high-resolution D1 high quality onto the DVR. This system provides excellent recorded video with the time and date stamped in so it could be used as evidence by the police. The camera video can be even set up to record to the remote and safe location the cloud so it cannot be stolen with text and email alerts.
For large installations the DVR can view up to 16 individual CCTV cameras. It produces simultaneously recorded images from all 16, storing images digitally on its internal hard drive. Using a mouse to control the unit, the stored videos can then be played back by camera number, time and date, or by an alarm.
