Apart from remedy solutions to retrieve deleted CCTV footage, there are several things that you should know to avoid losing data.
Back Up CCTV Footage & Other Files Regularly
If you have saved CCTV footage regularly, you won’t be caught unprepared when these files get deleted.
For the CCTV videos in SD cards or hard disks, you may upload them to your PCs on a weekly or monthly basis. By doing so, you can build your own storage bases with less worries of losing data.
Apply Multiple Storage Options
Just as the saying goes, you cannot put all the eggs in one basket.
Similarly, it is beneficial that you save CCTV footage to multiple storage options, which include SD cards, DVRs/NVRs (hard disk), Cloud and FTP servers.
So next time you may recover deleted CCTV videos from multiple storage devices when you find footage erased or damaged.
Be Aware of Recording Time of Your Security Cameras/Systems
Most DVRs/NVRs start loop recording when their hard drives are full. Mind that once the DVRs/NVRs overwrite their storage, original images and videos will be removed and it becomes impossible to recover overwritten CCTV footage at this stage.
Actual recording time of DVRs/NVRs may vary with storage capacity, resolution, bitrate, compression and the number of cameras. But it is still possible for you to calculate the general recording days of a CCTV security system so that you may back up CCTV videos in time.
