Is CCTV forensics possible?

CCTV forensics refers to the technical procedure of analyzing digital traces remaining on storage devices (HDD, SD card, etc.) to restore deleted or damaged videos.

Therefore, even videos that have been deleted from the system after the storage period, if the storage device has not been newly overwritten, may be partially restored depending on the situation.

However, since CCTV videos are mostly stored in a cyclical manner, as time passes, new video data overwrites the existing video.

In other words, immediately after deletion, the forensic recovery rate is high, but as weeks or months pass, the possibility of recovery gradually decreases.

To proceed with CCTV forensics, you must first obtain the consent of the owner or manager to access the equipment, and in cases related to legal disputes or criminal cases, it is important to follow evidence acquisition procedures through search and seizure warrants or court preservation orders.

Then, the forensic specialist will image the storage media and proceed with restoration work in a state that prevents original damage.

If there are suspicions that the nursing home damaged or deleted the video, CCTV forensic results can also confirm whether the video was arbitrarily deleted or whether there are traces of manipulation.

Restored videos can be used as evidence for subsequent criminal complaints or civil lawsuits, so it is best to proceed with restoration procedures with forensic specialists or attorneys as soon as possible.
