Resetting the Camera

If there is an issue with seeing the camera on the NVR, try to correct 

it by resetting the camera to factory default settings. 

To reset the camera to factory default settings:

1.  Make sure the camera is connected to the NVR via the Ethernet cable to 

the PoE ports.

2.  Press and hold the Reset button on the back of the camera.

3.  While still holding the Reset button, disconnect and then reconnect 

the Ethernet cable. Continue to hold the button for 15 seconds before 

releasing. 

4.  The camera will reset to factory defaults and restart, which may take a 

couple minutes.

(optional)

Before installing the camera:

• 

Decide whether to run 

the cables through the 

wall / ceiling (drilling 

required) or along the 

wall / ceiling.

• 

If you run the cables 

along the wall / 

ceiling, you must run 

the cable through the 

cable notch on the 

base. This will keep the 

camera base flush to the 

wall / ceiling when mounted.

To install the camera:

1.  Set the camera in the desired mounting 

position and mark holes for the screws.

2.  Drill the holes, then feed the cable through the 

mounting surface or cable notch and mount 

the camera stand to the surface using the 

provided screws. Make sure all three screws 

are fastened tightly at the connection points.
