Frequently Asked Questions - QT878 Q-See
How do I install the Q-See QT878 security camera?
Mount the camera using the included bracket. Connect the BNC video cable to a DVR or monitor. Plug the DC 12V power adapter into an outlet. Adjust the camera angle and tighten the screws.
Can I view the camera remotely?
This is an analog camera, so remote viewing requires a DVR with network capabilities. Connect the camera to a compatible Q-See DVR and configure the DVR's network settings.
How do I reset the camera to factory settings?
There is no reset button on the camera itself. Reset is done via the connected DVR. Refer to your DVR manual for instructions.
Why is the night vision not working?
Check that the IR LEDs are not obstructed. Ensure the camera is in a dark environment; if there is too much ambient light, the IR may not activate. Also verify the power supply is adequate.
What is the maximum distance for night vision?
The QT878 can see up to 20 meters (65 feet) in complete darkness thanks to its 24 IR LEDs.

Use a soft, dry microfiber cloth to gently wipe the lens. Avoid using liquids or abrasive materials. For stubborn dirt, slightly dampen the cloth with water.
Is the camera weatherproof?
Yes, the QT878 has an IP66 rating, meaning it is protected against dust and strong water jets. It can be installed outdoors.
