1. Safety Instructions and Notes

•Please read these safety and operating instructions before putting the camera into operation.

•Keep the operating instructions in a safe place for later use.

•The Standard Box Camera is designed for indoor use only and it must not be installed where exposed to rain

and moisture.

•Do not operate the cameras beyond their specified temperature, humidity or power ratings.

•Never open the case of the camera because there are precision parts inside. Otherwise a trouble or

an accident may result

•Do not put anything metallic and other foreign substances through the vent. A trouble fire or electric shock

may result.

•Be sure to turn off the power before installing or making connection.

•Pay attention when laying the connection cable and observe that the cable is not subject to heavy loads,

kinks or damage and no moisture can get in.

•Do not install the camera in places exposed to vibrations and shocks.

•Be very careful not to drop or shock the camera while carrying it in.

•Do not orient the camera to the sun.

•Do not make any modification to the unit (neither to the software nor the hardware). Improper modification

voids the warranty and can cause malfunctions or damages.

The manufacturer accepts no liability for damages resulting from unauthorized or improper modifications to

the unit

•Some of types of lenses may cause hunting, light amount drop or other problems. In such case, readjust the

lenses.

•Because of the digital image device characteristics, images may look rugged at high temperatures. This does

not mean the camera is in trouble.

•The warranty becomes void if repairs are undertaken by unauthorized persons.

•Contact the supplier if any functional problems arise.

Cleaning:

•Do not touch the surface of the imaging device.

•Keep clean the lens surfaces at both sides of front and rear..

- Offers unparalleled image quality across all lighting conditions especially at high-contrast environments

like indoor and outdoor of daylight time

- Delivers natural color

- Offers the highest resolution of 540TVL(horizontal)

- Eliminates compromising image noise by blooming or vertical smear

- Reduces the color rolling and flicker(EFR version only of NTSC camera)

- Eliminates the color rolling of NTSC system by line-lock synchronization (AC24V version)

- Offers on-screen menu

With ICR mechanism,

- Enhances its sensitivity about 10x at night time

- Can accepts the infrared light

With 24VAC/12VDC dual power design,

- Offers the flexibility of installation

- Ensures the reliability

Main features are;

• 1/3" RGB Color DPS SENSOR (Pixim Orca D1500series)

•Resolution of 540 Horizontal Lines

•10x sensitivity enhancement by removing the optical filter

•Switches to B/W and able to accept the infrared spectrum at night mode

5. Installation and commissioning Instructions

•Make sure the power is removed before the installation.

•Follow the order for applying power.

First connect the low voltage (DC12V or AC24V), then plug the AC adapter to AC outlets to avoid an

improper reset from power jitter and a damage from the surge voltage when no load.

5.1. Attaching the lens

•Remove the Dust Protection cap from the lens mount

•Screw the lens onto the camera without using force

5.2. Setting the back focus lock

The back focus is the distance between the lens support on the camera and the image sensor. Optimum focus

is only possible when the correct distance is set. It may be necessary to set the back focus in individual cases

due to production tolerances of the lens. The iris of the lens must be open as wide as possible. (smallest F

value) to set the back focus. For lenses with automatic iris control, you will require a ND filter (gray filter) to

prevent the iris from closing in bright light.

Setting for lenses with a fixed focal distance

If the focus cannot be set exactly by turning the focus ring (lens), please proceed as follows;

1. Point the camera at an object with sufficient contrast. The distance to the object should be longer than

1,000 x the focal distance.

2. Open the iris on the lens

3. Set the focus of lens so that the distance at the lens is close to infinity but not to exact infinity position.

4. Loosen ④Back focus Adjustment Lock Screw one~two turns on the camera with industrial “+” driver

5. Rotate ①Back Focus Adjustment until the optimum focus is achieved.

6. Tighten ④Back focus Adjustment Lock Screw again.

7. Trim the focus precisely at lens if necessary.

Setting for lenses with a variable focal distance (zoom)

If the focus changes as the focal distance changes, please proceed as follows.

1. Point the camera at an object with sufficient contrast at a distance of approximately 2 meters.

2. Open the iris on the lens

3. Set the maximum focal distance (Tele) at the lens

4. Set the optimum focus with the focus ring

5. Set the smallest focal distance (wide angle)

6. Loosen ④Back focus Adjustment Lock Screw one~two turns on the camera with the industrial “+” driver

7. Adjust ①Back Focus Adjustment until the optimum focus is achieved. Steps 3,4,5 and 7 may be needed

to repeat several times to obtain the best results

8. Tighten ④Back focus Adjustment Lock Screw again

5.3. Installation

The camera has a 1/4” thread insert on its top and bottom side for mounting the camera to a tripod or the wall

or ceiling with a corresponding mount.

5.4 Commissioning

•Connect the power to the camera firstly

•Plug the power adaptor to the mains supply secondly

•The camera is ready for operation

5.5. Power Supply Connections

Camera can work with either 12VDC or 24VAC, dual voltage power. It does NOT require the polarity-matched

connection for 12VDC supply. Primary and secondary grounds are completely isolated to avoid the possible

ground-loop problems. Its excellently wide operating voltage range of 10.5V-30V for DC and 12-28.8V for AC

gives an extra flexibility at the installation.

6. Start up

When the camera is powered properly, it starts up with initializing the internal parameters and the filter switch

mechanism. The filter switch unit repeats IN and OUT two times at each power up and just after RESTORE

FACTORY SETTINGS.

PRESET Descriptions

<NORMAL> Produces an image that has average contrast and suitable for normal indoor or low-

contrast outdoor scenes.

INDOOR Provides better leveling of image for in the darker areas of the scene. Suitable for

indoor scenes that have higher contrast lighting.

OUTDOOR

Optimized for outdoor sunlit applications and provides better leveling for the brighter

areas. Suitable for outdoor scenes having high contrast between sunlit and

shadows.

FL-LIGHT

Reduces the color rolling by fluorescent lights when line-lock is not

available(NTSC). DC auto iris lens is required.

Use Line-lock sync. with AC24V supply for the best result against the color rolling if

possible.

LOBBY Optimized for the common installation at lobby.

WAREHOUSE Optimized for the common installation at warehouse

In such cases, find the optimal settings in CUSTOM setting of EXPOSURE menu

7.5 CUSTOM menu

To enter CUSTOM menu, press button at <CUSTOM . . . > of EXPOSURE menu.

EXPOSURE Descriptions

<WDR MID> Medium level of the dynamic range control for each PRESETs.

WDR HIGH Increases the dynamic range control. Some highlight area may washed out.

CUSTOM... Provides more flexible compensation other than WDR MID, WDR LOW, WDR HIGH

BLC...

Compensates the brightness of main object against the bright back light.

A zone out of CTR SPOT, UPPER1/3, MIDDLE1/3, LOWER1/3 can be set.

Dynamic range control is inoperative if EXPOSURE is set to BLC.

WDR LOW Decreases the dynamic range control.
