What Do Overwritten Files Mean 

When some crimes happen, surveillance videos will be the key to investigations and evidence. When a video is overwritten, what does this mean? Overwrite means to record or copy new data over existing data when a file or directory is updated. When data is overwritten, new information is recorded over the old information. The unused file system clusters are used to record new information. This happens when the user continues to use the disk for various purposes and writes new files over the old ones. 

Can You Recover Overwritten CCTV Files

Most people have this kind of question: can deleted CCTV files be recovered? Is it possible to recover overwritten CCTV or DVR data? 

can you recover lost cctv files

You can easily recover deleted CCTV files. But there is absolutely very little chance of recovering CCTV’s DVR videos that were overwritten. They are overwritten by another video and erased from the hard disc. You can recover videos that exist on the hard disk even if the hard disk is damaged to a certain extent. 

But if the hard drive is not completely overwritten, then there is still a chance to recover video from the CCTV camera hard drive.

3 Methods to Restore Lost CCTV Files 

In the following content, we will walk you through two methods to recover deleted videos from CCTV/DVR hard drives or SD cards.

Also, If your CCTV HDD is not completely overwritten, you can also try EaseUS data recovery software. Since the situation that data has been overwritten is more complex. We cannot guarantee that it is 100% helpful to retrieve overwritten files. Therefore, download our trial version for a try first. If you find what you have lost on the result page, you can buy this software and save it to a safe place. If not, I am afraid this tool can not help you.

Method 3. Recover Deleted CCTV from Backup

If you have backed up the surveillance videos to another hard drive or SD card, you can restore CCTV files easily from the backup.

Step 1. Find and open the video backup folder.

Step 2. Locate the video you deleted or lost from the CCTV or DVR hard drive/SD card.

Step 3. Copy and store the found video back to the disk/SD card.
