Testing for Power and Night Vision
After you connect your camera to the NVR, if you do not 
see a video image on screen and your NVR does not 
display a “video loss” message, you should test your 
camera to ensure it is properly connected.
1.  With the NVR powered on and your camera(s) still 
connected to the system, cover the lens end of your 
camera with your hand or an object to completely 
block it.
2.  Keep the lens blocked for 10 seconds. You should see 
a faint red glow from the infrared LEDs. This indicates 
that your camera has power and is working properly.
If you still do not have a video signal from the camera, 
ensure that the camera network cable is properly 
connected to both the camera and the NVR as shown in 
Step 2 on pages 5 and 6.
Other Tests
•  Connect the camera to a cable that has a working 
camera attached. If the camera works, the cable 
may need to be replaced. Please contact technical 
support or you can visit www.q-see.com/support 
for more info.
•  Connect the cable to a dierent channel on the NVR. 
If you see video, then the culprit is a bad channel input 
and the NVR may need to be replaced.
