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.
