Safety Warning
1. Handle the camera with care.
Be careful when handling the camera, do not drop it or subject
it to strong shock or vibration to prevent any damages to it. Do
not disassemble it or place it on an unstable base.
2. Do not install the camera near electric or magnetic fields.
Installed the camera away from TV, radio transmitter, magnet,
electric motor, transformer, audio speakers because the
magnetic fields generate from above devices will distort the
video image.
3. Do not install the camera in the high temperature environment.
Installed the camera away from stoves, or other heat
generating devices as the high temperature could cause
deformation, discoloration or other damages of the camera.
Install the camera at where the temperature range will stay
between 0 to 50(32 to 122).
4. Never face the camera toward the sun.
Never aim the camera at the sun or other extremely bright objects
whether it is in use or not.
5. Cleaning
Do not touch the surface of CCD sensor by hand directly. Use
a soft cloth to remove the dirt from the camera body. Use lens
tissue or a cotton tipped applicator and ethanol to clean the
CCD sensor and the camera lens. When the camera is not in
use, put the cover cap on the lens mount.
The new EQ250 series is a solid-state color video camera specially
designed for high quality surveillance applications. It incorporates
break through DSP technology that provides most reliable and
accurate color picture in security industry. The camera is
convenient to use with C-mount or CS-mount lenses and easy
back-focus adjustment help to achieve installation efficiency.

Major Parts Names and Their Functions
Rear (EQ250)
1. Focal Length Adjustment Ring
Use this ring to adjust the appropriate focal length according to the type of
lens. Rotate the ring clockwise for the CS-mount lens, rotate it
counterclockwise for the C-mount lens. The factory setting is C-mount.
2. Lens Mount
To mount an appropriate C-mount or CS-mount lens.
3. Locking Screw
Use the locking screw to fix the focal length.
4. Lens Connector (4 pin socket)
To connect to the lens plug of the auto IRIS lens.
5. Control Switches
There are 6 control switches located on the sideboard, which are for the
setting of the special features. The switches in orders are for Flickerless,
Back Light Compensation, Electronic Shutter, Automatic Gain Control,
Line-Lock and Auto Iris Lens type.
FL(Flickerless) On/Normal
When picture flicker fiercely, turn FL on, then the camera will stabilize the
speed of electronic shutter at 1/100(NTSC) or 1/120(PAL) automatically,
and reduce the flicker immediately. The default setting is Normal.
BLC (Back Light Compensation) On/Normal
When BLC is turned on, the AGC, ES and IRIS operating point is
determined by averaging over the center area instead of entire field-of-view,
so that a dimly-lit foreground object at center area can be clearly
distinguished from brightly-lit backgrounds.
BLC should not be used unless it is needed to compensate for back-lit. The
default setting is Normal.
ES (Electronic Shutter) Off/On
ES ON: The camera continuously adjusts the shutter speed from 1/60
(NTSC), 1/50 (PAL) second to 1/100,000 second according to the
luminance conditions of the scene.
ES OFF: The shutter speed is fixed at 1/60 (NTSC), 1/50 (PAL) second.
Set ES OFF, when auto iris lens is used or flicker is observed under a very
bright fluorescent lamp. Otherwise, turn ES on for optimum performance.
The default setting is ON.
AGC (Automatic Gain Control) Off/On
AGC ON: The sensitivity increases automatically when light is low.
AGC OFF: A-low-noise picture is obtained under a low light condition.
The default setting is ON.
LL (Line-Lock) Off/On
To select the sync mode between Internal Sync.(LL off) and Line-Lock
(LL on).
Set the line-lock off, the camera will synchronize to the internal time base.
Set the line-lock on, the camera’s vertical synchronization can be driven by
the AC signal in the power lines.
Note: Line-Lock sync mode operation is possible only when used with an
AC power source; it’s not possible with a DC power source.
VD/DD (Auto Iris lens Type)
For video drive auto iris lens, please set switch to VD. For direct drive iris
lens, set switch to DD. The default setting is DD. Wire the cable of lens to
lens connector according to the following table.

Direct Drive
Cnt- Cnt+
Lens Connector
6. IRIS Level Control
Brightness Level can be adjusted from the IRIS level VR while using the
direct drive lens.
#" Turn
counterclockwise to L to get darker picture.
#" Turn
clockwise to H to get brighter picture.
7. V-Phase Adjustment
The vertical phase may require adjustment to synchronize the vertical phase
of the camera with other camera in the system when it is to be used in the
line-lock sync mode. Make the adjustment when the vertical phase of the
camera does not match with other cameras.
8. Mounting Base and Fixing Screws
To use when the mounting bracket is required while mounting the camera.
The mounting base can be attached to either the top or the bottom of the
camera, fix the mounting base onto the camera by using the 4 supplied
fixing screws.
9. Video Output Connector
BNC VBS 1.0 Vp-p, 75ohm
10. Audio Out Connector
11. Power Cable (EQ250)
12. DC12V/AC24V Screw Terminals (EQ250A)
Installation Instructions
1. Remove the cover cap from the top of the lens mount.
2. To attach a C-mount/CS-mount lens, turn the focal length adjustment
ring to the appropriate position.
Note: If a C-mount lens is used, please make sure the focal length
adjustment ring is set at C position before fixing the lens.
3. Screw the lens firmly onto the lens mount. Insert the lens plug in the
lens connector if the auto iris lens is used.
4. Tighten the locking screw.
5. Connect the video output of the camera to a color monitor or other video
device through a 75 ohm type coaxial cable with BNC female connector.
6. Plug the power cord to the outlet.
7. Once the image appears on the monitor, adjust the focus and diaphragm
of the lens to obtain the best picture.
8. If the subject is not in focus when adjusting focus of lens, do focal
length adjustment as following:
i. Loosen the locking screw of the focal length adjustment ring.
ii. Take picture of subject at a distance more than 20m away from the
iii. Rotate the focal length adjustment ring to bring the subject in focus.
iv. Tighten the locking screw while the adjustment is completed.
