NOTES:
1. The extension cable must be a single stretch of cable between the DVR and
camera. You cannot connect multiple extension cables to each other.
2. Extending camera cable runs beyond the included cable length may require you
to connect the power supply directly to the camera rather than to the extension
cable.
3. Indicators that your cable run may be too long:
• Camera loses video when switching to night vision.
• Video is permanently black & white (even during day time).
• Video is unclear, soft, or distorted.
4. For more information on extension cables, visit lorex.com and search for the
model numbers of the cables above.

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 surface when mounted.
Cable Notch
4. Feed the camera cable through the camera base.
5. Connect the video and power cable as detailed in the section
‘Setting up the Camera’.
6. Attach the camera base to the mounting surface using the included
screws.
7. Position the dome cover over the ball camera and twist clockwise
onto the camera base. Do not tighten completely.
8. Move the ball camera to the desired position. While holding the ball
camera in place, twist the dome cover the rest of the way to secure
it to the camera base. Holding the camera prevents it from moving
while tightening the dome cover.
9. Use the included Allen key to tighten the adjustment screw on the
dome cover.
10. Remove the vinyl film from the camera lens when your installation is
complete.
