• Check if the cameras are properly connected to the back of the DVR and to a

power source.

source and each of the cameras.

• Check CAMERA SETUP from the MAIN MENU to see if any of the cameras are

turned off.

I have lost video footage

• 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.

The cameras are not

appearing in

• Check if you have selected START ROTATE in the FUNCTION TOOLBAR. The

cameras will start to sequence according to the sequence dwell time.

• To stop, click STOP ROTATE in the FUNCTION TOOLBAR.

Nothing is recording

however all the images are

appearing on the screen

• 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.

The camera picture is

too dark

• Adjust the camera's brightness settings under MAIN

• Your camera may not be getting enough light towards it during the day.

Adjust the sunshade (top of camera) to allow more sunlight.

The night vision will not

turn on/I can’t see at night

My DVR will not acquire an

IP address

• 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.

The NETWORK SETTINGS

screen on the DVR has no

information

• Be sure the DVR is properly connected to the router. There should be green link

indicator lights if the DVR is properly connected.
