How many days footage will my CCTV HDD store?
There are a number of factors which will determine this. The main things to consider are:
- Recording quality. The higher the quality the less time a given hard drive will record for. HD 1080P produces 5 times more data than standard definition D1.
- The number of frames per second you record at. This is something you can change without compromising your CCTV system.
- The number of cameras you have on your system. Each camera requires space for its footage to be stored.
Length of time footage is stored on our HD 1080P DVR recorders at 6 frames per second
Number of cameras | Hard drive size | Storage time (days) |
4................. | ............1 TB ............ | .............12 |
4................. | ............2 TB ........... | .............24 |
8................. | ............3 TB ........... | .............18 |
8................. | ............4 TB ........... | .............24 |
16................ | ............6 TB * ......... | .............18 |
16................ | ............8 TB * ......... | .............24 |
* 2 drives fitted. Lowering the frame rate to 3fps will double the above recording times.
Tip
Because our HD DVRs are hybrid consider using a combination of standard resolution and HD cameras at the same time on the same recorder. Using standard definition D1 or 960H cameras in less critical areas means you reduce the amount of data going onto the hard drive and extend recording times.
