An introduction to the Prime CCTV Hard Drive Calculator. The calculator is able to calculate both days and hard drive size depending on what is required. The tool based on www.primealarms.co.uk/tools/cctv-hard-drive-calculator gives an accruate expectation. Of course this is dependant on the system and the camera type, but can be used as a useful guide when comparing CCTV systems and CCTV resolutions. With inputs based on the number of cameras, the resolution, the frame rate and recording type the tool can calculate what is required.
