Solution
- Verify that the power is connected to all components in the system.
- Verify that the power switch is ON.
- Verify the status of cables or the connection of cables.
- Check the power supply voltage (normal 24 VAC) directly at the
camera.
- Check the camera settings.
- Check the video quality directly at the camera with a service
monitor.
- Check the quality and length of video cables, and possible EMC
interference.
- Check the quality of connectors and potential moisture/corrosion.
- If the lens or the dome window is dirty, clean it with a clean cloth.
- Power-cycle the camera and power supply, or reset the camera using
the configuration menu [Main > System > Reboot].
- Check the connection of the power cable and the status of the
camera.
- Initialize the camera [Main > System > Initialize].
- Check the power rating of the power supply.
- Measure the voltage at the camera (since there could be a drop in
voltage due cable length). The power consumption increases when
the camera is moving (especially at high speed) and when the heater
is on. The voltage at the camera should always be 24 VAC (+/- 10%).
- Check that the RS-485 cable is connected correctly.
- Check the ID/Protocol/Baud rate/Termination setting.
The value in the Setting Type menu (Installer Setup > Camera ID
Setup > Setting Type) must be HW (Hardware), or the dip switch will
not be enabled.
- Check the voltage level of the dome camera and the status of the
camera.
- Check that the camera is connected to the proper power.
- Check to see if the camera faces directly into the sun or a
fluorescent lamp. If so, reposition the dome. - Check for flickers on
the screen.
