How big is the video recorded by the surveillance camera every hour?
High-definition 720P( 1280×720) format: based on the 4Mbps code stream, the total data storage capacity of 1 day is 4Mbps÷8×3600 seconds× 24 hours ×( 1 day) ÷1024.
SD 4CIF(704*576) storage format: based on 2Mbps code stream, the total data storage capacity of 1 day is 2Mbps÷8×3600 seconds× 24 hours ×( 1 day) ÷1024 = 2/kloc-0.
CIF(352*288) storage format: based on the code stream of 5 12Kbps, the total data storage capacity of 1 day is 5 12Kbps÷8×3600 seconds× 24 hours× (1day) ÷/.

Monitor the resolution of the camera
For surveillance cameras, clarity is very important. As we all know, the higher the resolution of the camera and the higher the pixels of the sensor, the clearer the image will be.
There are several specifications, the common ones are 1 10,000,10.3 million, 2 million and 3 million, and the corresponding resolutions are 1280× 720 (720p), 1280× 960 and/kloc-0 respectively.
A camera with higher resolution and pixels will get better results, but it will take up more bandwidth and memory space, and the recording time of the same size hard disk will be shorter.
Therefore, when choosing the resolution of the camera, we should also consider the storage problem while pursuing clarity and choose the one that suits us. Of course, the combination of timing video and motion detection video will make the actual valuable surveillance video stored in the hard disk for a longer time.
