Troubleshooting > Signal Loss / No Image

Poor Connections - A poor lead connection may cause signal loss or interference so check that each component is firmly plugged in and any joints (soldered or otherwise) have been made well and solid with no shorts or crossed wires.

Lack Of Power - May cause a lack of picture or other intermittent results. Check your equipment works on a short lead to rule out unsuitable cable runs. Ensure that each add-on item such as cameras, PIRs etc. have their own adequate power supply source. Finally try powering the unit locally with a suitably rated power supply unit (12V DC 2A). See Powering Monitors for help on this.

Long Cable Runs Causing Signal Loss - A long cable run may result in poor or complete signal loss. Firstly check if this is the cause by testing the camera and screen on a short test cable. If the problem disappears then both units are working correctly.

Next check if the correct cable is being used. If your cable is below specification then it will need replacing with a more suitable heavier duty cable. See Connections and Wiring

All above checks should be carried out in any situation where one unit does not appear to be receiving a signal whether video, audio or data from another unit.
