Frequently Asked Questions

CCTV Video Recovery FAQ

Can formatted or deleted CCTV footage be recovered?

Yes! Formatted DVR hard drives usually retain raw video frames. Our forensic PC-3000 DVR software extracts unindexed video fragments channel by channel.

Can overwritten CCTV footage be fully recovered?

Partial recovery is possible from unallocated sectors that have not yet been overwritten by new camera streams. Immediate power shutdown increases yield.

How long does video recovery take and what is the policy if unrecoverable?

Evaluations take 24 hours. Most CCTV video extractions complete in 24-48 hours. Under our 'No Data, No Fee' policy, you pay nothing if no video is recovered.
