• Check if the cameras are properly connected to the back of the DVR and to a
power source.
• If using the 4 to 1 power connector, make sure it is plugged into a power
source and each of the cameras.
• Check CAMERA SETUP from the MAIN MENU to see if any of the cameras are
turned off.
• The cameras might have been tampered with. Be sure to check that all
connections are secure and properly set.
• The HDD overwrite feature is enabled. When enabled, the DVR will begin
overwriting the earliest stored footage when the HDD is full.
• Unplug the power to the cameras and/or DVR and plug it back in.
• Check if you have selected START ROTATE in the FUNCTION TOOLBAR. The
cameras will start to sequence according to the sequence dwell time.
• You must be in LIVE viewing mode.
• To stop, click STOP ROTATE in the FUNCTION TOOLBAR.
• You must initiate the recording to start by pressing the RECORD button on
the remote.
• Check under Record Setup in the main menu to make sure all the cameras are
set to ON.
• Check your record schedule to make sure the DVR is set to record that hour.
• Verify that the HDD is installed and formatted in the DEVICE menu.
• Adjust the camera's brightness settings under MAIN
MENU→CAMERA→COLOR.
• Try moving your camera to a brighter area.
• Make sure the camera is not pointing directly into a light source.
• Your camera may not be getting enough light towards it during the day.
Adjust the sunshade (top of camera) to allow more sunlight.
• Night vision turns on automatically when the sensor detects a lack of light. If
your cameras are in a space with too much light, the night vision will not
turn on.
• Check the Ethernet connections, ensure that the connection lights are lit (on
the router and the back of DVR).
• Try using a different Ethernet cable and/or a different port on your router.
• Be sure the DVR is properly connected to the router. There should be green link
indicator lights if the DVR is properly connected.
• Make sure the DVR IP Allocation is set to DHCP. This is a standard default
setting that will work in most networking situations.
• Power cycle the DVR to ensure it is properly connected and the IP Allocation is
set to DHCP.
