How To Save Security Camera Footage Before It Overwrites

Preserve home, business, dash-camera, or doorbell footage before the system automatically deletes it.

All Guides
Short version: The best clip is the one you export before the camera overwrites it.

Why This Matters

People often discover too late that their camera system only keeps footage for a few days. A package theft, trespass, crash, or suspicious vehicle may be visible, but the clip disappears before anyone exports it.

Your first job is to save the original footage. Your second job is to make it easy for someone else to know what the clip shows.

Step By Step

  • Write down the date, time window, camera name, and camera location before you start exporting.
  • Export the full relevant time window, not just the dramatic few seconds. Include approach, incident, and departure when available.
  • Save the original export without trimming or adding marks.
  • Make a shorter working clip only after the original is saved.
  • Capture a still image if a face, vehicle, license plate, clothing, or object is briefly visible.
  • Store the file in at least two places before the camera system overwrites it.
  • Add the footage to your evidence index with the camera location and time offset of important moments.

Checklist

  • Original video export
  • Short review clip, if helpful
  • Still images of important frames
  • Camera name and location
  • Time zone and system clock accuracy note
  • Backup copy
  • Evidence index entry

Common Mistakes

  • Do not screen-record the app as your only copy if the system allows a real export.
  • Do not trim the only copy.
  • Do not assume the camera clock is accurate. Note if it is fast or slow.
  • Do not wait for police or insurance before saving footage.

When To Stop DIY

  • If the footage shows an active emergency, call 911 first.
  • If footage includes neighbors, children, medical events, or private interiors, be careful about sharing it publicly.
