Reasons for Video Loss from CCTV Security Cameras
Usually, the CCTV or surveillance camera video recordings are saved using either DVRs (digital video recorders) or NVRs (network video recorders) depending on the type of security camera. The DVR/NVR software saves the footage on external hard drives, USB Stick, and SD card of different sizes that enables you to save and view the videos later. But sometimes, hardware or software issues might occur that can lead to DVR/ NVR video corruption or footage loss. The CCTV security camera video loss issue can be related to:
- Camera hardware or software
- Inadequate power supply
- Internet connectivity
- Faulty wiring of the whole CCTV system
- Accidental deletion of the CCTV footage
- Loss during file transfer
- Other probable reasons could be hard drive corruption, formatting, loss of radio signal, faulty IR night vision, or old firmware.
How to Fix CCTV Camera Video Loss?
Surveillance or CCTV camera videos and images are automatically recorded and archived via DVR/NVR in the hard drive, SSD, memory cards, USB drives, Cloud, or portable media players. The lost videos or photos on these drives can be easily recovered either from backup, CCTV recovery tool or at an ISO certified data center.

How to recover overwritten CCTV footage
Overwritten files mean videos or images were deleted from the storage drive and then another footage was written (saved) upon that unused file cluster on the storage drive. So clearly speaking, it is impossible to restore overwritten CCTV footage.
But having said that, some recovery tools such as Stellar Photo Recovery, are able to scan the DVR/ NVR drives by using file signature. And if they manage to find traces of file information, they may recover overwritten CCTV footage as well.
So you may try advanced recovery software once to restore overwritten CCTV footage.
DONT’S when Security Camera Videos Missing!
- Do Not use the DVR/NVR of security cameras once any error is detected.
- Do Not format the security camera storage drive.
- Do Not delete or add anything to avoid overwriting the CCTV camera storage drive.
- Do Not try to repair the surveillance camera or its DVR/NVR on your own. Seek the help of professionals.
Checkpoints once the video loss on CCTV Camera is detected
Whichever brand and type of surveillance cameras you are using, be it – Foscam, Night Owl cameras, Swann CCTV, Netgear, Hikvision, or Zmodo, etc., below checkpoints, will help you prevent losing photos and videos in the future.
- Check the power connections, fix any loose cables, change the faulty old power cables, and re-launch the camera and software.
- Connect the camera to a different port on the NVR or DVR. If the problem is with the port, the video might be displayed after changing to a new port.
- Check if the camera is properly connected to the power adapter.
- Ensure the length of the Ethernet cable or BNC (Bayonet Neill–Concelman) you are using is not more than the specified length mentioned in your security camera specification. The longer the cable than the specified length, the poor the image quality.
- In case you are using wireless IP surveillance cameras, check whether the router and PoE (Power over Ethernet) switch, are working properly.
- Ensure the infrared (IR) LEDs are on, and the camera is receiving enough power.
- Update the firmware. A regular firmware update can tackle video loss or not playing issues and lets your system run smoothly. You can download the latest firmware from the security camera’s website.
- If you are still unable to view the video, switch off all the devices and reboot the cameras including DVR or NVR. Next, unplug all power switches and plug again.
