What is Security Footage Review?
Security footage review is a needle-in-haystack problem: an incident lasting seconds is buried in hours of a static scene. This workflow applies static-frame filtering — the same technique used in professional CCTV investigation — locally in your browser. The scanner samples the recording at one-second steps, measures how much each frame changes, and reports only the windows with real activity, each with a peak thumbnail and a jump button. Nothing is uploaded, so it is safe for evidence footage, HR cases and anything covered by privacy rules that forbid third-party processing.
Common Uses for Security Footage Review
- Locate a break-in or package theft window in a day-long export
- Check overnight recordings without scrubbing at 16× speed
- Find the moment a door opened in an otherwise static hallway cam
- Prepare timestamped incident notes for a police report or insurer
Frequently Asked Questions
My export is dozens of separate files — what then?
Scan them one at a time, or concatenate them first with ffmpeg (`ffmpeg -f concat -i list.txt -c copy full.mp4`) and scan the single file. Keep each file under a few hours for comfortable scanning.
Will it miss slow movement?
Possibly at Low sensitivity — a person creeping in dim light produces small per-second changes. Use High sensitivity and accept more windows. The scanner is a filter for where to look, not a verdict.
Can I use the flagged timestamps as evidence?
The tool gives you precise source timestamps you can cite, and the Timestamp Frame Grabber can export the exact frame. For formal evidence, keep the original recording untouched and note timestamps against it.
