Generally, the video storage time of public security monitoring is about 2 weeks to 2 months. If the time is too long, the cost is relatively high, so it is generally about 1 month. There is no hard and fast rule on how many days to keep surveillance videos belonging to public security organs. But generally speaking, the storage period of surveillance video shall not be less than one month.
Can the surveillance video from a year ago be restored?
The surveillance video from a year ago can't be recovered. At present, the storage time of surveillance video is generally not more than one month, and the national unit is generally not more than three months. If there was no backup file at that time a year ago, it would be gone and never seen again. Some backup video files will be saved, but if you want to watch them, you need to apply to the relevant public security personnel. A few years ago, users had to take out or replace the surveillance video from the video recorder to save it. The video tape was easily lost, stolen or inadvertently erased. Moreover, most video pixels are not high, and the video quality decreases with the increase of copy number.
