INSTALLATION
1. Use the supplied three screws to attach and fix the bracket to wall.
2. Remove the Joint Lock from the bracket by turning it counterclockwise. Then, connect the Joint Lock to the
backside of the camera (turn clockwise).

4. Connect the camera video output to DVR’s video input with a 75Ω coaxial cable. Then, connect the camera to
power with a DC 12V power supply.
5. After installation, please follow the next section below to start selecting focal length and adjusting focus. For
further camera angle change, the tilt angle of the camera is limited to 30 degrees and the right/left pan angle is
limited to 15 degrees each.
NOTE: Please use the correct power adaptor, DC12V (regulated), to operate this unit. The power tolerance of this
unit is DC12V ± 10%. Over maximum DC 12V power input will damage this unit.
NOTE: To ensure the camera has sufficient protection against moisture, an extra waterproof measure, such as by
using an insulating tape, must be used to cover the power and video connectors after connection.
FOCAL LENGTH SELECTION AND FOCUS ADJUSTMENT
NOTE: The appropriate temperature for focal length selection and focus adjustment is 0˚C ~ 40˚C.
1. Rotate the front cover to remove it.
Note:
The camera front cover must be removed for focal length selection and focus adjustment:

Please finish focal length selection and focus adjustment ASAP and replace the front cover back as
described in the following steps.

Please prevent doing this in the high moisture environment. If it’s inevitable, please finish it ASAP.
2. In the camera, you’ll find two handles to adjust the focal length (from f3.8mm to f9.5mm) and focus respectively,
as illustrated below.
Move the handle near the main board first to find the best surveillance area, and move the handle near the IR
LED panel to adjust the sharpness of the image later.
Focus (Image Sharpness) Adjustment Tips:

For the environment below 15°C, aim at the view which is 15 meters away from the camera for focus
adjustment.

For the environment above 35°C, aim at the view which is 5 meters away from the camera for focus
adjustment.

For the environment between 15 ~ 35°C, aim at the view you want to see for focus adjustment.
3. Find the desiccants supplied in the sales package, and place them into the camera as shown below.
NOTE: Please finish step 4 ~ 5 in 10 minutes in case the desiccants absorb too much moisture before the
installation is completed and are unable to keep the air dry in the camera anymore.
4. Replace the front cover.
NOTE: Make sure the front cover is fastened well.
5. Slide to mount the shield on the camera.
