Troubleshooting
9.1 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
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
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.

General Maintenance
·
Ensure that nothing is obscuring the field of view, position the camera to ensure the subject is in
field of view and can be seen clearly.
·
Ensure that the Microphone is clear and not obscured at all.
·
Routinely clean the montitor to prevent dust build up as this can effect the performance. We
recommend a damp non-abrasive microfibre cloth.
·
Routinely check the connections for power and data to ensure the connections are secure and
solid.
·
Check that the monitor is firmly attached to the wall mounting bracket.
·
Check playback in the monitor to ensure it is recording & triggering properly on the SD Card
