1.2 Check Accessories
Before the installation, please check the accessories one by one according to the packing list.
Please make sure all the components listed are includes.
1.3 Open the Device
Please open the box and then take out the speed dome. See Figure 1-1.
Figure 1-1
Note:
There are two types of IR intelligent speed dome which are shown in Figure 1-1, please refer to
the actual object for details.
There is laser light and IR light on the laser speed dome, the laser light is used for light
compensation while the IR light can be used to indicate whether the laser light is on or off, the
laser light is enabled when the IR light is on.
1.4 Dial Switch Setup
1.4.1 Dial Switch Address and Function
The corresponding functions of dial switch for both analog speed dome and HDCVI speed dome
are different, which will be introduced respectively.
1.4.1.1 Analog Speed Dome

3
Open the cover of the speed dome; you can see there are two dial switch buttons on the PTZ
mainboard. You can use them to set speed dome address, baud rate and parity. Please refer to
Figure 1-2 for the dial switch address.
Figure 1-2
1.4.1.2 HDCVI Speed Dome
Open the cover of the speed dome; you can see there are two dial switch buttons on the PTZ
mainboard. You can use them to set speed dome address, baud rate and HD/SD video mode.
Please refer to Figure 1-3 for the dial switch address.
Figure 1-3

4
Note:
When HDCVI intelligent speed dome only uses coaxial control, dial-up and other related RS485
setup don’t have to be conducted.
1.4.2 Dial Switch Setup
Users must set the address, Baud rate or HD/SD video mode which is used by the speed dome
before controlling it. Only after all these settings, can the speed dome respond to its control
commands.
Note:
As for the wall-mounted speed dome, you need to install back the transparent cover component
after taking out the EPE and setting the dial switch address.
Users must reboot the speed dome after resetting some specifications, which makes the new
setup take effect.
There are two dial switch buttons on the speed dome PTZ which are used to confirm the speed
dome address, baud rate, parity or HD/SD vide mode. It is 1 when you set the button as ON. For
address setup dial switch, 1 is the lowest bit, 8 is the highest bit; for the Baud rate and parity
setup dial switch, 1 is the lowest bit, 4 is the highest bit. (Intelligent speed dome self-adaptive
PELCO-D, PELCO-P, industrial standard protocol, control protocol don’t need dial switch setup).
1.4.3 Address Setup
The speed dome uses dial switch to set address, the encode mode adopts binary system. 1 to 8
is valid bit. The highest address bit is 255; see Figure 1-4 for address and you can refer to the
sheet 1-1 for more information.

Figure 1-7
The factory default connection mode is shown in Figure1-8; the jumper (connection board) is
plugged into pin2 and pin 3, which means 120Ω resistance is not connected to the device.
Figure 1-8
If you want to connect the 120Ωresistance, you have to pull the jumper out of pin 2 and pin 3,
and connect to pin 1 and pin 2, then 120Ωresistance is connected to the circuit, see Figure 1-9.
Figure 1-9
1.5 Reset and SD Card Installation (network speed dome)
You can see there is a RESET button and Micro-SD card slot on the PCB after you open the dial
switch cover. See Figure 1-10. Reset button is used to reset network system. Micro-SD card is
used to save the data.

1.6 Speed Dome Installation
Note:
The installation of this section can be applied to IR Analog Intelligent and IR Network Intelligent
Speed Dome.
The speed dome has various brackets suitable for different environments. For detailed
information, please refer to chapter 2 to chapter 6. Here we are going to install the analog speed
dome with the analog speed dome wall-mounted bracket.
1.6.1 Quick Installation Connector
Now you can install the quick installation connector. Please twist Teflon tape around the screw
thread of the quick installation port and turn it into the screw thread of the wall mount bracket.
Use M4 stainless screws to secure firmly. See Figure 1-11.

8
Figure 1-11
1.6.2 Cable Connection
Connect the safety hook of the IR speed dome cover to the hook of the quick installation port.
Connect the reserved integration cable of the wall mount bracket to the corresponding power
cable, video/audio cable, RS485 control cable, alarm port, high frequency cable, fiber cable
(if necessary) of the multiple-function composite cable of the IR speed dome. Paste the
insulating tape in the connection position to do the proper waterproof work. See Figure 1-12.
Figure 1-12

9
Note
The video port is covered the heat shrink tube of high shrinking ratio. After the video connection,
please heat the tube to make sure the video port is damp proof and water proof.
1.6.3 Install the speed dome
Step 1
Pull the integration cable and multiple-function composite cable to the wall mount bracket slowly.
Step 2
Line up the straight edge of the flange of the IR speed dome to the straight edge of the quick
installation port, and then push the speed dome to the bottom of the port slowly.
Step 3
Use your hands to turn the M6*14 stainless screw (with spring washer) to the Ф6.5 hole of the
straight edge of the IR speed dome. Turn other two M6*14 stainless screws to groove of IR
speed dome flange. Use the inner hex tool to fix these three stainless screws. Now you have
completed the installation. See Figure 1-13.
Figure 1-13
Step 4
Please make sure:
The three stainless screws of the quick installation port are firmly secure.
The IR speed dome is fixed.
The speed dome is straight.
The steel wire connection is firm.
After your installation, the interface is shown as in Figure 1-14.
