Do not use this product under circumstances exceeding specified temperature and humidity
ratings.
12. Avoid pointing the camera directly to the sun or other extremely bright objects for
prolonged period of time avoiding the risk of permanent damages to the imaging sensor.
13. The attached instructions are for use by qualified personnel only. To reduce the risks of
electric shock do not perform any servicing other than contained in the operating instructions
unless you are qualified to do so.
14. During usage, user should abide by all electrical safety standards and adhere to electrical

1.3 Function Description
 Super Communication
Address, baud rate and protocol could be changed both from Dip switch or from software.
 Multilanguage OSD Menu
The language display on screen menu, the available language is English etc.. User can set the
function or parameter, or check the related information through the OSD.
 Privacy Masking
In the monitoring scope, areas that users can’t or aren’t willing to make show in the screen of
the monitor can be set as privacy protected area (area masking), such as area where
customers enter the password in monitoring system of bank or some doorway.
 Alarming Set
Details please refer to the OSD menu.
 Focus

4
The auto focus enables the camera to focus automatically to maintain clear image. User can
use manual focus to in special condition.
Under the following conditions camera will not auto focus on the camera target:
(1) Target is not the center of the screen;
(2) Attempting to view images that are far and near at the same time;
(3) Target is strongly lighted object, such as neon lamp, etc.;.
(4) Targets are behind the glass covered with water droplets or dust;
(5) Targets are moving quickly;
(6) Monotonous large area targets, such as wall;
(7) Targets are too dark or faint.
 BLC
If a bright backlight is present, the target in the picture may appear dark or as a silhouette, BLC
enhance the target in the center of the picture, the dome uses the center of the pictures to
adjust the iris. if there is a bright light source outside this area, it will wash out to white, the
camera will adjust the iris so that the target in the sensitive area will properly exposed.
 Iris Control
Factory default is automatic camera aperture, in mode of which camera senses changes in
ambient light through moving and adjust automatically lens aperture to make the brightness of
output image stable.
Users can through pressing OPEN or CLOSE iris adjusting keys, manually adjust the aperture
size to get the required picture brightness.
By controlling the keyboard up, down, left, right or zoom to resume auto iris (auto iris is
recommended).
 Auto-recognize to Protocol and Module
The dome can auto-recognize to the corresponding protocol and module during self-inspection.
eg. Module: Sony, CNB, LG, Samsung, domestic etc.
Protocol: PELCO_P, PELCO_D etc.
 3D Allocation
With this function users can move the image of some area to the center of screen according to
specified level and vertical coordinates and auto control to zoom according to zoom parameter
set.
 Day/Night Switch
With auto day/night switch function, when the illumination is low, the picture will auto switch
from day to night mode and when the illumination is high enough, the picture will auto switch
from night to day mode.
 Ratio Speed
Intelligent pan and tilt speed is variable depend on the zoom factor. When zooming in, the
speed will become slower and when zooming out, the speed will become quicker.

5
 A-B Scan
Dome circularly scan close-up real-time scene according to A-B points at setting speed in both
horizontal and vertical directions.
 Pan Scan
Dome 360°clockwise continuous scan the display scene at setting speed in horizontal direction
under the condition that pitch angle remains the same.
 Preset
After the dome camera keeps arbitrary PTZ location, it will automatically move to the defined
position when preset is called.
 Guard Tour Scan
Dome patrol scans according to certain edited preset order.
 Power Off Memory
This feature allows the dome to resume its previous preset or status after power is restored. By
default setting, the dome support power up memory, which improves the reliability and avoids
repeated settings of the parameter.
 Park Action
If users don’t operate the dome in set time, it will automatically run preset specific mode (pan
scan, A-B scan, park action, cruise, preserve action etc.).
 Zero Alignment
There is a point specified as zero point. When the dome is working, the preset point is not
accurate because of something caused by the operator. User can make the dome automatically
enable the zero alignment by operational order.
 Auto Flip
In the manual tracking mode, when a target goes directly beneath the dome, the dome will
automatically rotate 180 degree in horizontal direction to maintain continuity tracking. When the
dome flips, the camera starts moving upward as long as you hold the joystick in the down
position.
2 Installation
2.1 DIP Switch Settings
2.1.1 Preparation
Before installation, make sure that the protocol , baud rate and address code used by the
product is fully consistent with the control system. Corresponding DIP switch site can be seen
below:

6
2.1.2 Address Settings
DIP switch SW1 is the address settings of camera. It is a 8-bit switch, each switch corresponds
with 0 or 1 in the Binary code. OFF status means 0 while ON status means 1.
(See illustration above) Turn on the 1st and 3rd (allocated to ON position) and get the binary
code 00000101, so the correspondence address is 5.
Detailed settings please refer to the back “Address Code Mapping Table”(appendix Ⅳ).
2.1.3 Baud Rate Settings
The 4th and 5th DIP Switches set the Baud rate. Factory-default setting is 2400bps.
Baud rate: 1200bps、2400bps、4800bps、9600bps selectable
2.1.4 RS-485 Bus Matching Resistance
The 8th bit of DIP switch SW2 is to select the matching resistor. To the control center, in order to
prevent the reflection and interference of RS-485 communication signal and other signals, the
parallel matching resistor is needed in the communication interface of dome camera at the end
away from the control center.

7
DIP switch SW2 has a control switch of matching resistor. That the 8th bit micro-switch turn to
the ON state (set as below) means having connected the matching electricity to RS-485 bus.
2.2 Connection
Connection of RS485
Before connecting, please turn off the power and read carefully the instructions of all connected
devices.
