Hello all, I have some questions regarding DVR and NVR data recovery mentioned below.

When I am going to recover a DVR or NVR drive, some frames are merged with another frame. For example, I have a 10-minute video and an 8-minute video of a camera 1 video and 2 minutes of camera 2 In this case, I lost 2 minutes of footage on camera 1.

PS: I don't have any clear picture; it's happened due to overwriting, data carving, or a proprietary filesystem. If anybody knows the answer, kindly share your thoughts and, if possible, share any white papers or case studies. It's helpful for my better understanding.
