Recording Time required

Have you considered:


a. Hard Drive size
b. Number of cameras
c. Frame rate for DVR
d. Resolution
e. Quality of recording Usually 5 levels
f. Compression method used

The length of time you can record for is affected by:

a. Hard Drive size: 250GB, 500GB, 1TB and 2TB options. DVRs store recordings directly onto a Hard Drive. Once storage space has run out, most DVRs can be set to automatically erase old footage as new footage is recorded. Choosing a Hard Drive size can depend on how long you wish to keep footage stored for.

b. Number of cameras: Most DVR units come in 4, 8,16 and 32 camera varieties

c. Frame Rate (fps - frames per second): 25 fps per camera is ‘real time’ as you would normally see on TV. 4-6 fps per camera is suitable for most situations. The fps rate is split between the total number of cameras connected to the DVR unit. So, a 100fps DVR with 4 cameras inputs will record at 25 fps per camera. Reducing the frame rate can save HD space.

d. Resolution and the e. Quality of recording: The better or bigger the image, the larger the size of the recording will be as more ‘image data’ is stored. QCIF(176x120), CIF (352x240), 2CIF (704x240),D1-4CIF 704 × 576 .

f. Compression methods: JPEG, MPEG, MPEG4 and H.264 Advanced Video Coding.

Ask yourself:


1. How long do I need to keep footage available for in order to retrieve footage later?

2. Will I be away for long periods of time while my CCTV system will need to be operating?
