CCTV Camera Storage Calculation Formula Yes, the CCTV storage calculator software online can give you quick answers to the CCTV storage needs. But the results are far from preciseness – different CCTV storage calculators can provide you divergent outcomes. More importantly, they don’t apply to EVERYONE. So, we have got this DIY CCTV storage calculation formula for you to calculate the required CCTV camera and hard disk storage space on your own: Storage Space (GB) = Bitrate (Kbps) * 1000/8 * 3600 * 24 * Cameras * Days/1000 000 000 *1000/8 = to convert kbps to Bytes *3600 = to convert from seconds to hour *24 = to convert from hour to day Cameras = total number of cameras Dyas = total number of days you want to record With the above CCTV storage calculation formula, you can now be off to calculate CCTV storage or the hard disk capacity for CCTV. +++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ CCTV Storage Calculator Formula Example If you have 2 cameras whose maximum bitrate is 1024 Kbps and want to record for 7 days nonstop, according to this CCTV camera storage calculation formula: Required storage space = 1024 * 1000/8 * 3600 * 24 * 2 * 7/1000 000 000 = 154.8288 GB ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ You can also apply this formula to the CCTV storage calculation of different brands, including the Reolink IP camera storage calculator, CCTV storage calculator for Samsung, Hikvision, Panasonic, Axis, Hoenywell, HD-SDI, Auetura, Milestone, Bosch, etc. Note that the results worked out by the above CCTV storage calculation formula may not be exactly the same with your actual storage needs, as the CCTV camera storage calculation is impacted by various factors. So, What Impacts the CCTV Storage Calculation Below we list the main determinants for CCTV storage calculation, which could afect your CCTV camera reocrding capacity. Resolution – The high the resolution, the larger the CCTV camera storage capacity in days is required. Compression – Video compression is a kind of technique that reduces the size of original video file formats and thus occupies less CCTV storage space than the original files. The popular video compression formats include H.264, MJPEG and MPEG4. (Read the comparison between the H.264 and MJPEG security cameras). Bitrate – Higher camera bitrate contributes to better video quality, which on the other hand, also means greater CCTV storage capacity required, as you can infer from the CCTV storage calculation formula above. And it is also affected by the resolution and compression formats. Lower resolution and highly compressed videos will require less bitrate. Camera – The number of cameras you use can also impact the CCTV storage calculation. If you use multiple cameras simultaneously, more CCTV storage space will be required. Days – The longer CCTV recording retention period is, the larger CCTV storage capacity is required. When you utilize the CCTV storage calculation formula, note that it is calculated by days, so you need to convert the hours to days if the camera records in hours. On top of these, CCTV storage calculation can also be influenced by other factors, such as the audio recordings, recording modes (motion triggered recording or 24/7 recording), amount of motion activities, lighting conditions of the scene, etc. Even if the IP camera or hard disk drive storage space doesn’t meet the required CCTV storage capacity according to the CCTV storage calculation formula, there is NO need to worry! Normally, the original videos will be overwritten by the new ones when the CCTV storage reaches its maximum capacity. Just remember to back up the important documents before they are overwritten. Bonus: Wanna know how long your CCTV cameras can record with a certain amount of storage space, say, 2TB HDD, read this to figure it out. Can’t-Miss Tips to Maximize CCTV Storage Capacity Now that you have grasped the CCTV storage calculation tool, the next question is how to maximize your CCTV storage capacity. These following practical storage-saving tips can do the trick to serve your purpose. 1. Choose H.264 IP Cameras As mentioned above, H.264 video format can greatly affect the CCTV storage calculation. Without compromising the image quality, H.264 format can reduce the size of a video by more than 80% compared with MJPEG format and 50% with the MPEG-4 format, thus optimizing the CCTV camera storage capacity.
