First: stop the footage being overwritten
Your recorder overwrites its oldest footage automatically. If you have a theft or an incident, the clock is ticking — on a system that keeps 15 days, footage from 14 days ago may be gone tomorrow.
So the first job is to export the clip, or at least lock it. Many NVRs let you lock a recording so it is not overwritten. Do this the same day if you can.
Exporting from the NVR, step by step
- Plug a USB pen drive or USB hard disk into the NVR's USB port. Use a drive formatted as FAT32 or exFAT; the NVR's own format tool can do this.
- Open Playback, choose the camera and the date, and find the incident on the timeline.
- Use the clip or backup tool to mark a start time a few minutes before the incident and an end time a few minutes after.
- Export each relevant camera separately. Include the cameras that show the person arriving and leaving, not just the moment itself.
- Choose MP4 if the recorder offers it. Some recorders export in their own format and also save a small player on the drive — keep that player with the files.
- Copy the files to a second location, such as a laptop, and keep the USB drive as the original.
Check before you hand it over
- Play the clip on a computer, not just on the NVR.
- Confirm the date and time on the footage are correct. A clock that has drifted causes confusion later — note the difference if there is one.
- Write down the camera name, location, and start and end times of each clip.
- Never edit, trim or re-encode the original files. Make a separate copy if you want a short version to show someone.
What the police usually need
For an FIR or complaint, the police will usually accept a copy of the clip on a pen drive or CD to begin with. If the case goes to court, electronic evidence such as CCTV footage needs a certificate under Section 63 of the Bharatiya Sakshya Adhiniyam, 2023, which replaced Section 65B of the Indian Evidence Act from 1 July 2024. The certificate states how the footage was produced and that the system was working properly.
The person responsible for the CCTV system usually signs this certificate, and an expert part may also be needed. The investigating officer or your lawyer will tell you exactly what is required for your case. In serious cases the police may also take the hard disk or the whole recorder — keep a copy of the clips before handing it over if you can.
What insurers usually ask for
For a burglary or damage claim, insurers typically want the FIR copy, the footage showing the incident, and photos of the damage. Some ask for proof that the CCTV system was working before the incident. Exporting a short clip of a normal day before the incident helps show that.
Why Insurers Ask About CCTV →Privacy when sharing footage
Footage of identifiable people is personal data. Sharing it with the police or your insurer for an incident is reasonable; posting it on social media or WhatsApp groups is a different matter and can cause problems of its own. Share only what is needed, with the people who need it.
Need help pulling footage?
If you cannot find the recording, the export fails, or the disk shows errors, do not format or replace the disk — it may still hold what you need. Call a technician first. We service CCTV systems installed by other companies too, after an inspection visit.

Can I record CCTV footage on my phone and send that?+
It is better than nothing as a quick share, but a phone recording of a screen loses detail and timestamps. Always export the original clip from the NVR as well.
What is a Section 63 certificate for CCTV footage?+
It is the certificate under the Bharatiya Sakshya Adhiniyam, 2023 that lets courts accept electronic records like CCTV footage. It replaced the old Section 65B certificate from 1 July 2024.
My footage is already overwritten. Can it be recovered?+
Usually not once the recorder has written over it. That is why exporting or locking the clip quickly matters, and why sizing storage for enough days is important.
Which format should I export in?+
MP4 where available, because most computers play it. If the NVR only exports its own format, keep the player it saves alongside the files.
