Cannot view DVR on the

computer

• Verify the following while referring to the included networking guide

• Make sure you are entering the proper IP address of the DVR. You will enter the Internal IP address into

the Internet Explorer address bar when the computer is connected to the same router as the DVR

• You will enter the external IP address into the Internet Explorer address bar when the computer trying

to access the DVR is not connected to the same router. This will require an Internet connection

• Port forwarding will need to have been setup according to the networking guide

• Follow the instructions found on www.portforward.com for detailed instructions or contact your

router manufacturer for assistance with port forwarding on your particular model of router

• Make sure you are logged into the computer as an administrator to install the required application and

ActiveX controls

The color on the camera

picture is too purple, blue,

etc

• Try adjusting the settings in the camera setup screen to improve/change the image quality. Unusual

coloring can also be caused by the type of lighting that is used. The cameras do not react well to

halogen lighting. Try focusing the cameras away from these lights

• Make sure that the cameras are not pointing directly at a light source such as a lamp or a sunny

window

My browser keeps freezing • Make sure you have an up to date browser and that the proper ActiveX options are selected. If they are,

you may need to re-install your browser. (Internet Explorer version 6 or higher)

Camera Troubleshooting

I cannot see at night with

my IR night vision cameras

• The night vision turns on automatically when light levels drop. Try the camera in a pitch black setting.

The areas that it is in may have too much light and may not activate the sensor

• The LEDs need to reect o an object to view it in the dark so make sure there is an object for it to

reect o within reasonable range

My camera is not displaying

any image

• Verify the connections are snug and tight tting. Disconnect and reconnect each connection.

4pin/4pin, power/power, RCA/RCA

• Make sure the power adapter is plugged in to an active electrical outlet

• If everything is connected, cup your hands around the camera lens and you should see the red LEDs

illuminate. Make sure it is dark enough to activate the light sensor

• If the LEDs do not illuminate, try switching the power adapter with a working camera’s power adapter.

This will indicate if it is the power adapter which needs to be replaced

• If no power/video signal even with the new power adapter, connect the camera that is in question to

a working cable. (Disconnect a working camera and connect the camera in question to that cable set)

The camera should function correctly. If the camera functions correctly the test indicates that there is a

bad cable

• Verify the pins on the 4PIN DIN connection are not bent and are being properly inserted to the proper

connector
