3. Settings, Installation and Connection
3.1 Settings of 7" Dome Camera ID, Transfer Rate and Communication Protocol
Before installing the Dome Camera, please confirm the communication protocol,
baud rate and local address code of the control host, and then the DIP-switch should
be set to be in complete accordance with that in control system. Its corresponding
DIP-switch settings and connecting line can be seen in picture 1:

7
Picture 1
3.2 Settings of Dome Camera ID
Before the Intelligent Dome Camera is used, its address code should be firstly set
by (SW1) 8 bit code switch on PCB board with binary system 8421 code. The largest
encode address is 255, and the number 1 indicates “on”, while the number “0” means
“off”. (As it shown in picture 2): Set each Dome Camera ID code and the keyboard
input of corresponding ID on LCD:

8
◆ The new settings will not be effective until the Dome Camera reboots.
3.3 Settings of Dome Camera Communication Protocol
No.1、2、3、4 on PCB board SW2 is the communication protocol settings. As it
is shown in picture 3:
The setting◆s of speed dome camera communication protocol do not work until
computer reboots.
3.4 Settings of Dome Camera Transfer Rate
No.4、5 on PCB board SW2 is the communication baud rate settings. The default
value is 2400BIT/S. The Baud rate is 2400BIT/S, 4800BIT/S, 9600BIT/S,
19200BIT/S optional, as it is shown in picture 4.
As shown in the picture above: The first switch is in the “ON” status,
while the rest VAD switches are “OFF”, the Camera ID is 1. Click the “CAM”
button on the control keyboard, and then input number “1”. Then click “Enter”
again, which indicates that the ID is set as NO.1 control ID. The Dome Camera

3.5 Installation and Connection
1. The installation and connection of the IP Intelligent Dome Camera should be
implemented under local provisions by people who own the technical qualifications of
CCTV system installation.
2. Please refer to the silk print on PCB and the installation manual for the detailed
information of the connection of each line.
3. Avoid direct touch to the lower cover of the dome to prevent scratches and the loss
of image quality, for the cover is a high-level optical instrument.
4. To ensure the image quality, the lower cover of the dome camera should be cleaned
periodically. When cleaning, take the lower cover down by holding the outer ring
carefully, avoiding direct touch; the acidic sweat on one’s finger might corrode the
coating of the cover. And the scratches made by hard objects might also result in a
blurry image. Please use a tender dry cloth or other substitutes to clean both the inner
and outer side of the cover. If the dirt is hard to clean, a neutral detergent could be
used; any cleanser which is for luxury furniture can be used for the lower cover.
Installation Preparation
3.6 Installation Requirements
 Installation must be carried out by professionals and the regulations should be
abided by to avoid any function failure.
 Check the accessories, and make sure that the location and the installation method
meet all the requirements.

3.7 7" Dome Camera Wall-mounted Bracket Installation
Wall-mounted Bracket Installation
Note: The wall which to be installed on should be solid and with no delaminating.
The bearing capacity of the installation location should be able to afford at least five
times of the total weight of the Dome, frame and pedestal, in order to avoid image
jitter caused by unstable installation.
a. When installing on the wall, put up a positioning on it first.
b. Use percussion drill to drill holes according to the marks; install four expansion
bolts (M8).
c. Put the cable、communication line and video wire through the frame holes, and set
aside enough cable for connection.
d. Fasten the frame to the wall by using four M8 nuts and four spacers, and then
install the dome.

11
Picture 7 Picture 8
Frame Installation
Take the frame from the bag, and then plug the cable into bracket from the top of
the bracket. Next, install the G1 1/2 screw on the top of the outer cover into the screw
holes of wall-mounted bracket, and fasten it with 2 bolts (M8).
Outer Wire Connection
Connect the BNC video interface of Dome Camera to the arranged video cable;
connect the power cord to the arranged power cord (AC12V/ AC24V). RS485 control
wire is connected to RS485 control wire layer out.
◆ Ensure that the positive and negative polarity of RS485 is properly
connected. “A” represents positive pole, while “B” negative pole.
If RS485 is wrongly connected, it could not control the Dome Camera.
a. Check the polarity of the plug and socket, and the connection of cable, then
power on.
b. When the self-checking starts, the Dome will turn 360°horizontally and then
90° vertically for the testing of the camera and the electrical and mechanical structure
of the Dome, and turn back to the initial position by the resetting program, then
vertically turn to 45°.When the Dome totally stops, the self-checking finishes and it
is ready to be under control.

12
◆Confirm that bearing capacity of the upright tube、wall and frame should be
able to afford at least five times of the total weight of the Dome, frame.
3.8 7" Dome Camera Ceiling-mounted Bracket Installation
Ceiling-mounted Bracket Installation
Note: The ceiling which to be installed on should be solid and with no
delaminating. The bearing capacity of the installation location should be able to afford
at least five times of the total weight of the Dome, frame and pedestal, in order to
avoid image jitter caused by unstable installation.
4. Dome Camera is controlled by keyboard
Intelligent control and all functions can be achieved by controlling the Dome
Camera with keyboard. Meanwhile, there are different operating methods for different

5. Other Functions
5.1 Object Tracking
Users can use the control lever on the control keyboard to move the Dome
camera up and down, or left and right to track the moving object or change the field of
vision, and change the visual angle or the image of the object by adjusting the focal
length. On the preset condition of auto-focusing and auto-aperture, the camera can
adjust itself quickly to get a clear view of the object according to the environment
during its moving around.
﹡Focal Length/Rotating Speed Auto-matching Technology
When manual adjusting the Dome camera with a long focal distance, the high
rotating speed of camera may cause image loss even touch the control lever slightly.
Considering the humanization, this ball camera is designed to auto-adjust both the
horizontal and vertical rotating speed according to the focal length which makes the
manual operation of tracking easier.
﹡Auto-overturn

19
When the operator turns the scene to the bottom (vertically) and continues
pressing the control stick, the camera will turn 180°horizontally and then upturn 90°to
get a back view, which provides a 180°whole-course continuous monitor.
5.2 Camera Control
5.2.1 Zoom Control
Users can zoom in or out by using the [WIDE] and [TELE] key on the control
keyboard to get an overall perspective or a close shot.
5.2.2 Focusing Control
Auto-focusing is the default setup. When zooming, the camera will auto-focus on
the center of the view to get a clear picture. In particular situation, users can manually
focus by using the [NEAR] and [FAR] key to get an expectant view.
◆Camera cannot auto-focus on following conditions:
a. The object is not in the center of the picture;
b. The objects from both far and near spots cannot be visually clear simultaneously;
c. The object emits strong light, such as neon light and spotlight;
d. The object is behind a class with water dew or dust on it;
e. The object moves very fast;
f. The object is large and monotonous, like a wall;
g. The object is too dark or blurry itself.
5.2.3 Aperture Control
●Auto-iris is the default setup. This function can auto-detect the light condition of
the environment and adjust accordingly to ensure the brightness of the output picture
stable.
●Users can manually adjust the aperture to get a needed brightness by using the
control keyboard.
●Users can restore the auto-iris function by using the control keyboard (Note:
auto-iris is suggested).
Note: When switching the aperture control to manual function, the current
control position will be locked, and it will not restore to auto-aperture function
automatically, even the scene changes. To restore the auto function, users need to

20
operate the control lever or give a control order.
5.2.4 Auto BLC
The camera will divide the scene into six areas to realize the auto back light
compensation. In a bright environment, it will auto-compensate the dark object and
adjust the lighting for the bright background, in order to avoid obtaining an
over-bright picture without visualizing the dark object instead of a clear image.
5.2.5 Auto WEB
Automatically adjust according to the lighting of the surroundings to recover the
true colors.
