Why is my CCTV camera not working or showing video loss?
CCTV video loss or blank screens on your monitor are usually caused by power adapter failures (SMPS shutdown), oxidized BNC/DC connectors, cable cuts, or recording channel issues. In Bangalore, power fluctuations can easily burn out basic SMPS adapters. TechBes offers local diagnostic services where certified technicians trace cable continuity, crimp connections, test power supplies, and inspect DVR settings to get your security back online quickly.

DVR vs NVR Issues
| Aspect | DVR (Digital Video Recorder) | NVR (Network Video Recorder) |
|---|---|---|
| Camera Interface | Physical coaxial ports; bad connectors cause static/bars | Network interface; IP conflicts cause offline errors |
| Power Allocation | Centralized SMPS; single adapter failure downs cameras | Integrated PoE ports; switches can lose power or overheat |
| Signal Range | Signal drops over long coaxial distance (100m+) | Lossless digital data; packets route over long network routes |
| Storage Alerts | Hard disk failure triggers repetitive beeping sound | Software logs capture disc write drops and push alerts |
How to Troubleshoot CCTV Video Loss or Connection Issues
Follow these diagnostic checks to identify and resolve common CCTV camera signal and power faults.
1. Inspect Power Status
Check if the camera's infrared lights glow at night. If not, replace the individual power adapter or the multi-channel SMPS box.
2. Verify Cable Connectors
Wiggle the BNC or RJ45 connector behind the camera. Rust or loose copper threads are the most frequent causes of signal dropouts.
3. Check Recording Unit
Confirm that other cameras on the DVR/NVR are working. If all are offline, inspect the recorder's main power brick.
4. Test with a Spare Port
Swap the faulty camera's cable to a known working port on the DVR. If it works, the original DVR port is damaged.
5. Book Expert Repair
If issues persist, schedule a diagnostic check on TechBes to get a certified technician with testing monitors to locate the fault.
