(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

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.

Anti-lightning, Anti-surge

This product is extremely air discharge and lightning protection with TVS tube technology, which can effectively prevent the transient lightning below voltage 3000V, surge and damages caused by other types of pulse signals.

However, necessary protective measures should be made in the premise of ensuring electrical safety for outdoor installation according to the actual situation :

·Signal transmission line must be at least 50 meters far away from the high-voltage

equipment or high voltage cable.

· Try to choose outdoor wiring laid down along the roof line.

· Way of sealed steel pipe buried wiring is used in the area which opened, and steel pipe

units grounded in one point. Overhead wiring is absolutely prohibited.

· In the strong thunderstorms area or areas with high induced voltage (such as high voltage substations), measure of installation of additional high power lightning protection equipment and lightning rod must be taken.

· Lightning protection and grounding of outdoor devices and lines must take the lightning-protection requirements of buildings into consideration, and comply with the related national standards and industry standards.

· System must be equipotential grounding. Grounding device must meet dual requirements of anti-interference and electrical safety, and should not be shorted or mixed with the adjacent lines in the strong power grid. When system is independently grounded, grounding impedance should be less than 4Ω, and cross-sectional area of grounding conductor must be not less than 25m2.

Clean Transparent Cover

In order to assure a clear image of dome, the under cover of dome should be cleaned regularly.

● Be careful when cleaning and hold the outer ring of under cover by hands to avoid directly touching with it. Because the acid sweat of finger membrane may corrode the surface coating of under cover. Hard tool scratching the under cover may lead to blurring the images of dome so that affecting image quality.

23

● Please use a soft enough dry cloth or other alternatives to wipe internal and external surface.

● If dirt is serious, user can use a mild detergent. Any senior furniture cleaning products can be used to clean the under cover.

Common Knowledge on RS-485 Bus

1. Basic Feature of RS-485bus

According to industry bus standard of RS-485, RS-485 bus is half-duplex communication bus with the characteristic impedance of 120Ω, whose maximum load capacity is 32 payloads (including the master device and the controlled device).

2. Mode of Connection and Terminal Resistance

2.1 Industry standard of RS485 bus requires that connection mode of daisy chain should be used between the devices with 120Ω terminal resistances connected at the both ends.

As shown in fig. 26 and fig. 27 is simplified connection, but the distance of part "D" shall not beyond 7 meters.

Fig 26 Fig 27

2.2 120Ω terminal resistance is connected as shown in fig 27.

120Ω terminal resistance is available in the circuit board and the connection is shown as following:

When needing to connect 120Ω resistance, toggle the 8th bit of DIP switch SW2 to "ON" . This way the 120Ω resistance is connected to the circuit.
