Preserve the footage first
The first task is to stop the video from disappearing. Most recorders and cloud systems overwrite older footage on a schedule. Find out how long yours keeps video, and if the incident is close to the edge of that window, act first and ask questions later. The guide on how long security cameras keep footage explains how retention works.
Lock or protect the relevant clips if your system supports it. Otherwise export them immediately. Save the original in a protected location with limited access, and work from copies from that point on.
Capture more than the moment of the incident
Investigators often need context. Export video from before the incident to show how people or vehicles arrived, and after it to show how they left. A longer window can show a vehicle parking, a person scouting the site, or an earlier visit.
Check every camera that might have seen the event, including ones at the entrance, along the route, and in adjacent areas. Different angles can show faces, plates, clothing or direction of travel that a single view misses.
Export in a usable format
Use the system's own export function rather than recording the screen with a phone, which lowers quality and loses timestamps. A good export includes the video file, the embedded time and date, and the camera name. Many systems offer a proprietary format that preserves the original data, and a standard format that plays almost anywhere.
Provide both when you can: the original export and a widely playable copy. If the original needs a special player, include it. Ask the agency what it prefers, since requirements differ. Then confirm the file opens on a different computer before you send it.
Check that the system clock was accurate. If the camera time was off, note by how much, because investigators will line up your footage with other sources.
Document chain of custody
Chain of custody is a written record of who had the footage, when, and what was done to it. It does not need to be complicated. A simple log can capture the following:
- Who found and exported the footage, with the date and time.
- Which system and cameras it came from.
- Where the original is stored and who can access it.
- Who received copies, when, and how they were delivered.
- Any steps taken, such as trimming a clip or converting a format.
Do not alter the original in any way. If you trim, enhance or convert a copy, label it as a copy and keep the untouched file. The more clearly you can show that the video did not change, the more useful it is. The guide to camera footage as evidence covers this in more detail.
What to include with the footage
Footage is easier to use when it comes with a short written summary. Keep it factual and avoid guesses about motive or identity. Include the following:
| Item | Why it helps |
|---|---|
| Date, time and time zone | Lets investigators align your video with other records |
| Site address and camera names | Shows where each view was taken |
| Clock accuracy note | Flags any offset between system time and real time |
| Brief description of events | Points to the relevant minutes without opinion |
| Your contact person | Gives investigators someone to call with questions |
| Export and handling log | Documents custody from capture to delivery |
| Related reports | Links your video to any incident or case number |
If your site has an incident report, share the case number so your footage can be attached to the right file. See the incident reporting workflow for a way to organize this.
Know the limits before you share
Whether you must hand over footage, and what you may share voluntarily, depends on who is asking and what the video shows. Rules vary by state. Video that includes audio, private areas, neighboring property or identifiable third parties may raise additional questions. Contracts with tenants, customers or clients may also affect what you can release.
Ask counsel before you send footage if there is any doubt. Many businesses set a written policy in advance so staff know who can release video, who approves it, and how requests are logged. For background on legal considerations, read business security camera laws.
Plan ahead so exports are easy
The easiest time to prepare for a request is before one arrives. Test your export process once, from start to finish, and write down the steps. Confirm that your system clock syncs automatically, and that the right people have access to export. Label cameras clearly so a name tells an officer where the view is.
Consider how quickly you notice incidents. Systems that are watched in real time catch events as they happen, and can save a clip with a verified description. The article on video-verified alarm response explains how that supports police response.
Common mistakes to avoid
Several errors reduce the value of good footage. The most common is waiting, which lets the system overwrite the clip. The next is recording the screen with a phone instead of using the export function, which loses timestamps and detail. Others include trimming the original instead of a copy, sending files that will not open on another computer, and forgetting to note that the camera clock was off.
Process mistakes matter too. Forwarding footage by an informal channel, such as a personal messaging account, can leave no record of who received it. Letting many people open and re-save the file can muddy the custody trail. Sharing video that shows unrelated people or private areas without checking the rules can create problems of its own.
Avoid all of these with a short written procedure. Name who exports, who approves release, where originals are stored and how each request is logged. Keep the procedure with your other site records, and review it after every request so it improves.
How VDS fits
VDS builds solar-powered mobile surveillance units for sites that lack power and internet. Each unit has a 5MP PTZ with 25x optical zoom and three 8MP wide-angle cameras, connected over dual-SIM 4G/5G cellular. A 24/7 US-based security operations center verifies events, responds with live talk-down through a loudspeaker, and then dispatches police with video.
That workflow means a person has reviewed the event before police are called, so the footage that goes with a dispatch is tied to a verified incident. To learn how monitoring works, see remote monitoring or talk to our team.
