3Device Installation
Fisheye camera mainly adopts ceiling mount installation, the installation location includes
ceiling and wall.
Attention
Please install the device in time after it is opened, which is to avoid the camera module
exposing in the damp environment for a long time.
Before the installation, please make sure the installation surface is thick enough to sustain
at least 3X weight of the camera.
For side cable outlet, please make sure the direction of side cable outlet is in accordance
with that of the installation position map when pasting installation position map, and pull
the cable through the cable slot of the pedestal and then lock the screws firmly.
Before you complete the installation and debugging, do not remove the electrostatic
attraction film on the transparent enclosure. Otherwise it may result in injury. After
removing the electrostatic attraction film, don’t touch dome enclosure in case it may leave
stain.
The installation figures below are for reference only, please refer to the actual device for
more details.
Please refer to Figure 3-1 for installation position map.

Step 1
Use the inner hex wrench from the accessories bag to unfasten the 3 hex screws on the dome
camera enclosure and then open the dome enclosure.
Step 2
Take the installation position map (shown in Figure 3-1) from the accessories bag and then
paste it on the installation ceiling or the wall according to the monitor area. Please dig three
bottom holes of the plastic expansion bolts according to the diagram. Take three expansion
bolts from the accessories bag and then insert them to the holes you just dug and then fix
firmly.
Note:
If you need to dig a hole to pull through the cable on top of installation surface, you need
to dig a cable exit hole on the installation surface according to the installation positioning
map.
If you need to pull through the cable on the side, you need to dig through the U-shape exit
hole on the side of chassis to form a cable access, and then pull the cable through the
side exit hole on the chassis.
Step 3
Adjust the device chassis and pull the cable through the exit hole. Make “TOP” direction of the
device identical with installation position map. Make sure the 3 fixture holes on chassis face

the three plastic expansion bolts on the surface. Take 3 self-tapping screws out from the
accessories bag and fix them on the three plastic expansion bolts to secure the dome on
installation surface.
Step 4
Take up the dome protection enclosure; aim the cable exit and cover the enclosure. Then use
the inner hex wrench from the accessories bag to fasten the 3 hex screws firmly.
