CCTV Camera Not Working? Troubleshooting Guide for No Image, Offline Cameras and Recorder Problems
Short answer
Start with power and cables: confirm the camera has power, the cable connectors are tight and the recorder or PoE switch is on. For IP cameras check the network link and IP address. If the recorder is not recording, check the hard drive. Persistent faults, burnt smells or water damage need a technician.
Common problems and checks
| Problem | Likely causes | Try this |
|---|---|---|
| No image on one camera | Power, cable or connector fault | Check power supply, connectors and the port on the recorder or switch |
| All cameras offline | Recorder, switch or power failure | Check the recorder, PoE switch, UPS and breaker |
| IP camera offline | IP conflict, cable or switch port fault | Check link lights, restart the camera, check network settings |
| Not recording | Hard drive full, missing or faulty | Check the recorder status; format or replace the drive |
| Picture blurry at night | Dirty lens, spider webs, glare from infrared | Clean lens and housing; adjust the camera angle |
| Cannot view on phone | Internet down, wrong login, app or cloud settings | Check internet, update the app, reset sharing settings |
| Picture flickers | Poor power or cable, interference | Check the power supply and cable quality |
Prevent problems
- Put the recorder and switch on a UPS.
- Use weatherproof connectors and proper junction boxes.
- Keep lenses clean and trim plants near cameras.
- Replace surveillance hard drives every few years and check them regularly.
- Keep firmware updated and use strong passwords.

Common questions
Why does my CCTV stop recording?
Common reasons are a failed or full disk, power loss or recorder settings. Check the recorder status screen.
How long do CCTV hard drives last?
Surveillance drives often last several years, but running constantly wears them. Check health regularly.
Should I fix wiring myself?
Simple checks are fine. Mains wiring and outdoor cabling are best left to technicians.
