1INTELLIGENT SPEED DOME INSTALLATION
1.1 Installation Environments
Basic Requirement
All installation and operation here should conform to your local electrical safety codes.
Before installation, please open the package and check all the components are included.
Please make sure the speed dome installation environment and installation mode can meet
your requirement. If there is special requirement, please contact your local retailer for more
information.
We assume no liability or responsibility for all the fires or electrical shock caused by
improper handling or installation.
1.2 Check installation space and installation location intension
Please make sure the installation environment has enough space to install the speed dome and

3.2 Installation Steps
3.2.1 Installation Environments
The ceiling mount speed dome can be installed in the hard construction ceiling in the indoor
environment. Before the installation, please make sure:
The ceiling is thick enough to install the expansion bolt.
The ceiling can at least sustain the 8x weight of the speed dome.
3.2.2 Installation Steps
Note: There are two outlet modes for ceiling mount installation.
Don’t drill hole on the ceiling, and open wire outlet from the side of the speed dome.
Drill hole on the ceiling, and concealed wire outlet from the ceiling.
Step 1
Install the default pedestal seal ring on the pedestal according to the way shown in Figure 3-1.
Step 2
Confirm installation position and outlet mode first, dig holes on the ceiling according to the
installation position map, and then put the three plastic expansion bolts into the holes you just
dug.
Step 3
Unscrew three locking screws on the enclosure by using inner hex wrench, and remove the
enclosure.
Step 4
Lay the outgoing line according to the outlet mode, and use three self-tapping screws to fix the
pedestal on the installation surface, and insert the screws into the expansion bolts.
Step 5
Use three locking screws to fix the dome enclosure on the pedestal.
So far, the camera installation is completed, and you can adjust the lens angle, zoom, focus and
etc on the WEB interface.

4APPENDIX Ⅰ LIGHTENING PROTECTION AND SURGE
PROTECTION
This series speed dome adopts TVS lighting protection technology. It can effectively prevent
damages from various pulse signals below 2000W, such as sudden lighting and surge. While
maintaining your local electrical safety code, you still need to take necessary precaution
measures when installing the speed dome in the outdoor environment.
The distance between the signal transmission cable and high-voltage device (or high-voltage
cable) shall be at least 50 meters.
Outdoor cable layout shall go under the penthouse if possible.
For vast land, please use sealing steel tube under the land to implement cable layout and
connects one point to the earth. Open floor cable layout is forbidden.
In area of strong thunderstorm hit or near high sensitive voltage (such as near high-voltage
transformer substation), you need to install additional high-power thunder protection device
or lightning rod.
The thunder protection and earth of the outdoor device and cable shall be considered in the
building whole thunder protection and conform to your local national or industry standard.
System shall adopt equal-potential wiring. The earth device shall meet anti-jamming and at
the same time conforms to your local electrical safety code. The earth device shall not short
circuit to N (neutral) line of high voltage power grid or mixed with other wires. When connect
the system to the earth alone, the earth resistance shall not be more than 4Ωand earth
cable cross-sectional area shall below 25 mm2.
