What are some of the common CCTV problems and how to fix them?

Below, are some of these common issues and their solutions to help you maintain a fully functional surveillance system as shared by TFTS Delhi’s leading CCTV maintenance company for commercial and residential properties.

No Video Output

One of the most common CCTV issues is when the camera does not display video. This can be due to loose or damaged cables, a failed power supply, or a faulty DVR/NVR. To resolve this, check all cable connections and ensure they are properly secured. If the power supply is not working, try a different outlet or replace it. If the issue persists, test the camera on another DVR/NVR port to determine if the problem is with the camera itself or the recording device.

Blurry or Out-of-Focus Image

A blurry or unclear image can result from a dirty lens, improper focus settings, or low-resolution settings. To fix this, clean the lens with a microfiber cloth to remove dust or smudges. If the image is still unclear, adjust the focus settings manually or through the DVR settings. Also, check the camera resolution settings and increase it if necessary.

Night Vision Not Working

If your CCTV camera is not displaying clear images at night, the infrared (IR) LEDs may be faulty, or there might be obstructions blocking the IR lights. In some cases, the camera may not be receiving enough power. To fix this, check whether the IR LEDs are glowing in the dark. If they are not, the camera may need to be replaced. Also, remove any objects that could be blocking the IR lights and ensure the camera has a sufficient power supply.

Flickering or Rolling Lines in Video

Flickering images or rolling lines in the video feed are usually caused by electrical interference, loose connections, or an incompatible power supply. To fix this, ensure that CCTV cables are kept away from electrical wires to minimize interference. Check and secure all connections properly. If the issue persists, confirm that the power supply matches the camera’s voltage and amperage requirements.

No Remote Access to CCTV Footage

If you are unable to access your CCTV footage remotely, the issue may be due to incorrect network configurations, firewall restrictions, or outdated firmware. To resolve this, check if your DVR/NVR is connected to the internet. Configure port forwarding in the router settings to allow remote access. Additionally, updating the firmware of your DVR/NVR and the mobile app can help resolve connectivity issues.

Motion Detection Not Working

When motion detection fails to function properly, it is often due to incorrect sensitivity settings, disabled motion detection, or obstructions in the camera’s view. To fix this, increase the motion sensitivity in the camera settings. Ensure that motion detection is enabled on the DVR/NVR. Also, clear any obstructions that may be preventing the camera from detecting movement effectively.

By performing regular maintenance and troubleshooting common issues, you can keep your CCTV system functioning efficiently. A well-maintained system ensures that your security is never compromised, providing you with continuous protection and peace of mind.
