Knowing Your DVR, the Digital Video Recorder
DVR Recording Resolution
This is one of the two most important factors! There are three types of DVR Recording Resolution qualities: CIF, Half D1 and D1.
CIF: This is the lowest and out-dated resolution-quality. Video and picture is produced at 320 X 230 Pixels. Distant subjects and objects become very unclear.
Half D1: Normal Quality / OK for Home and small business use, but does not produce fully professional and reliable evidence in all situations. Up to 720 X 260 Pixels.
D1: D1 records at up to 720 X 520 Pixels, which is equal to DVD Quality! In a professionally set-up CCTV System even further distant suspects have a good chance of identification.
DVR Frame Rate
The overall frame rate (Frames Per Second FPS) gives the number of pictures that can be captured into the video stream every second over all Video Inputs together. So a 50 FPS DVR Recorder with four Security Cameras connected can record at a max. of 12.5 FPS per camera. A 100 FPS machine can capture 25 FPS (Real Time) per camera as long as only four cameras are streamed in.
Most CCTV Systems are set up to record at 4 to 8 pictures per second for every camera, but often revert to Real Time when certain incidents happen or motion is detected.
We highly recommend at least 100 FPS DVR for 4 Camera CCTV Systems, 200 FPS DVR for 8 Camera CCTV Systems and 400 FPS for 16 Camera Systems.
H.264 Compression Vs MPEG4
H.264 Video Compression is by far superior to the older MPEG4.

H.264 Compression Vs MPEG4
H.264 Video Compression is by far superior to the older MPEG4.
- H.264 saves almost 50 % of Hard Disk Space
- H.264 reduces storage cost
- H.264 Greatly improves Remote Monitoring and View over the Web- Application Faster internet streaming
