CCTV Guide
A practical CCTV guide for Tabuk covering offline cameras, no picture, night vision, recording, remote viewing, DVR/NVR and power issues.
Before You Start
CCTV problems can involve camera power, cables, PoE, DVR/NVR settings, storage or network connectivity. Use safe external checks first and avoid opening power equipment.
Safety first: Do not open electrical appliances, live power supplies or sealed systems unless you are qualified to do so.
01Camera Is Offline
Check visible power/network connections and whether the affected camera has power. For PoE systems, the switch or recorder port may need testing.
Common causes
Possible causes include network loss, PoE/power problems, cable faults, IP configuration, or camera hardware failure.
Safe checks
Check whether the camera has power/IR indicators and whether the network recorder sees the camera. Avoid changing network settings without recording the original values.

Camera Has No Picture
Check the camera channel, cable and power status. Persistent no-picture faults may involve the camera, connector, PoE or recorder.
Common causes
Possible causes include power, cable, input, camera hardware, lens, or recorder channel issues.
Safe checks
Check the camera connection and try another known-good channel/port where appropriate. Persistent failure needs system diagnosis.

Night Vision Is Not Working
Check whether the lens is obstructed and confirm the camera has power. IR, sensor or configuration faults may require diagnosis.
Common causes
Possible causes include IR LEDs, low power, camera settings, obstruction, or hardware faults.
Safe checks
Clean the lens, confirm night mode/settings, and observe the camera in low light. Do not open the camera housing unnecessarily.

CCTV Is Not Recording
Check recording schedule, storage status and date/time settings. A failing hard drive or recorder configuration can stop recording.
Common causes
Possible causes include hard-drive failure, storage settings, recording schedule, camera connection, or recorder faults.
Safe checks
Check recording status, available storage, date/time and schedule settings. If the recorder reports a disk error, arrange service before losing more footage.

Remote Viewing Does Not Work
Check network connectivity and app/device status. Router, configuration or remote-access settings may need technical setup.
Common causes
Possible causes include internet outage, router changes, app/account settings, port/cloud configuration, or recorder network settings.
Safe checks
Confirm local viewing works first, then check the internet connection and app status. Avoid changing router or recorder network settings without a backup of the original configuration.

Several Cameras Stopped Together
This can point to shared power, PoE, network or recorder issues. Check the shared equipment rather than replacing cameras immediately.
Common causes
Possible causes include PoE switch/NVR power, network switch, power supply, cable trunk, or recorder problems.
Safe checks
Check whether the affected cameras share the same switch or power source. If multiple cameras fail simultaneously, system-level diagnosis is usually more efficient.
