During video surveillance plan stage, us often face a question – how many HDDs should I usage for my video surveillance system. Estimating or calculating the required video clip storage have the right to be quite an easy by using the formula, or it deserve to be complicated when considering countless factors including resolution, frame rate, video clip compression, and also bitrate settings. Us herein administer you a freeware which can calculate the video clip storage need of the camera based upon many this variable parameters. Making use of this calculator girlfriend can roughly estimate exactly how long have the right to a HDD record in her computer/DVR/NVR.

Running this straightforward software, you deserve to instantly calculation the total video clip storage because that your desired storage (number that days) per network camera. Additionally, you can use the formula together below:
Bitrate (Kbit/s) ÷ 8*3600*hours each camera will record per day÷1024÷1024= video clip storage (GByte)
How long have the right to a HDD record for your DVR/NVR?
|Recording channels||500G HDD||1TB HDD||2TB HDD|

If you use the H.265 network cameras and also NVRs, climate you have the right to reduce 50% video storage usage. By the way, us herein we administer you a summary table to present you the video storage as soon as a camera records in non-stop 24 hrs manner.
|Resolution||Bitrate (25fps)||Hours||Days||Weeks||Months||6 Months|
Note: 1Mbps = 1024 kbps; 1024Mbps = 1GByte
Disclaim: only for reference, the an outcome calculated through software/table is based upon regular H.264 codec, after several years" improvement, we reckon that the H.264 video compression performance has been substantially improved, therefore data may not precise for today"s H.264 IP cameras and DVRs/NVRs.
