Camera not showing on screen? Start with power, cable, and recorder checks first.

First-line checks

1. Confirm whether the issue affects one camera or multiple cameras
2. Check recorder power, monitor display, and the correct input source
3. Inspect camera power supply and visible cable damage
4. Swap the camera to another known working channel if it is safe to do so
5. Review recorder settings and channel enable state

Common causes

• Loose connectors, damaged power adapter, or weak splitter output
• Faulty BNC connector, cable damage, or water ingress
• Recorder channel issue or incorrect display/output settings
• Camera failure after surge, heat, or age-related wear

When not to force it

• Do not climb or open site wiring unsafely just to test quickly
• Do not replace multiple parts blindly without isolating the failing point
• If the recorder stores critical footage, avoid unnecessary resets before backup planning
