Note:
When using 5-direction button to operate OSD menu, the left and right buttons fail to realize
vari-focal and zoom function, then it needs to exit OSD menu and operate it again.

Note:
There is only one video port for some cameras, which is shown in Figure 2-9, it outputs HD
video signal by default, it needs to enable self-adaptation function in the OSD menu to switch

3Installation
Important
Please install the device in time after it is taken apart, which is to avoid the camera
module being exposed to damp environment for too long.
Before the installation, please make sure the installation surface should be thick
enough to sustain at least 3X weight of the camera.
Step 1
Take out the installation position map from the accessories bag, stick it on the ceiling or wall
according to the cable exit, dig holes on the installation surface according to the installation
position map, and see Figure 3-1. Pull out the camera cable through the cable exit on the
bracket pedestal, and install camera bracket.
Figure 3-1
If it is cement wall, it needs to install expansion bolt first (the installation holes of
expansion bolt need to be in accordance with bracket), then use self-tapping screws to
install bracket.
If it is wooden wall, you can just skip the first step, use self-tapping screws to install
bracket directly.
Step 2 Adjust the camera monitoring direction
If it is the model c or c (1), then use the L-shaped wrench in the accessories bag to loosen
the adjusting screws, adjust the camera to the specific direction which needs to be
monitored, then use L-shaped wrench to tighten adjusting screws and fix the camera, see
Figure 3-2.

Figure 3-2
If it is model a or model b, then loosen the M3 X 20 and M3 X 5 screws on the bracket
according to the direction shown in Figure 3-3, adjust the camera to specific monitoring
direction via rotating bracket and camera body, then fix the screws.
Figure 3-3
Step 3
Connect the video output port of device cable to the back-end HCVR device, and connect
power port to power supply.
Step 4 Adjust camera zoom and focus
If it is the model a, then it needs to adjust lens zoom and focus on the back-end HCVR
device to make the image clear.

8
If it is the model b, after displaying image on the back-end HCVR device, open the camera
lower cover and adjust lens focal length via focus/zoom lever to make image clear, and
then tighten the lever. Retighten the camera lower cover and complete camera installation.

Appendix Maintenance
Attention:
Please maintain the device according to the following instructions in order to ensure the image
effect and long-term stable operation of the device.
Maintenance for lens and mirror surface
The lens and mirror surface are covered with antireflection coating, so it may produce
hazardous substance and lead to performance reduction or scratch, dimness etc when it is
stained with dust, grease, fingerprint and so on, please refer to the following methods to deal
with once dirt is found:
Stained with dirt
Use oil-free soft brush or hair dries to remove it gently.
Stained with grease or fingerprint
Use soft cloth to wipe the water drop or oil gently to make it dry, then use oil-free cotton cloth
or paper soaked with alcohol or detergent to wipe from the lens center to outward. It is ok to
change the cloth and wipe several times if it is not clean enough.
Camera Body Maintenance
Use a soft dry cloth to clean the camera body when it is dirty, in case the dirt is hard to remove,
use a clean dry cloth soaked with mild detergent and wipe gently, make it dry later. Don’t use
volatile solvent like alcohol, benzene, thinner and etc or strong detergent with abrasiveness,
otherwise it will damage the surface coating or reduce the working performance of the device.
Maintenance for Dome Cover
Dome cover is an optical device, please don’t touch or wipe cover surface directly during
installation and use, please refer to the following methods to deal with once dirt is found:
Stained with dirt
Use oil-free soft brush or hair dries to remove it gently.
Stained with grease or fingerprint
