subject to change without notice.
PRECAUTIONS
1. Do not install the camera near electric or magnetic fields.
Install the camera away from TV, radio transmitter, magnet, electric motor, transformer,
audio speakers since the magnetic fields generate from above devices will distort the video
images.
2. Never disassemble the camera nor put impurities in it.
Disassembly or impurities may result in trouble or fire.
3. Never face the camera toward the sun.
Direct sunlight or severe ray may cause fatal damage to sensor and internal circuit.
4. Keep the power cord away from water and liquid.
Touching the wet power cord may result in electric shock.
5. Never install the camera in areas exposed to water, oil or gas.
Water, oil or gas may result in failure, electric shock or fire.

Do not touch the surface of sensor by hand directly. Use a soft cloth to remove the dirt from
the camera body. Use lens tissue or a cotton swab and ethanol to clean the sensor and the
camera lens.
7. Do not operate the camera beyond the specified temperature, humidity or
power source ratings.
Use the camera at temperatures within –10℃~ 50℃/14℉ ~ 122℉ and humidity between

PREFACE
The most technically advanced EHD series are the newest vandal-resistant Color Rugged
Dome Camera from EverFocus Electronics. The Color Rugged Dome Camera can withstand
a blow from a 10-pound sledgehammer and has a built-in heater that allows for operation in
low temperatures. It is perfect for all high-profile crime-prone applications such as building
entrances, retail stores, and shopping malls. EHD series are unquestionably one of the
world's toughest cameras and is your best choice for vandal resistance.

INSTALLATION
1. Loosen the 4 fix screws on the housing cover by using the attached wrench (Figure 1).
Please pay attention not to damage the lens.
2. Remove the camera.
To remove the camera, first unplug the wire connection on the back of the camera. Then
loosen the 2 locking screws on the camera base, push the camera base to the right (toward
heater direction, as shown in Figure 2), remove the camera from the mounting base.
Reinstall the camera and the cable while the base mounting is completed.

3. Mounting the base.
Attach the base to the wall or ceiling, fix the base by the 4 setscrews attached in the
accessory pack. Please make sure if the mounting is strengthened enough to
support it, if not, please reinforce the mounting according to the environment.
Note: The diameter of the screw hole isψ4.7mm.

Caution: To prevent moisture leaking into the housing, apply an appropriate
gasket or sealant around the conduit connection.
4. Wire Connection
The camera comes with a conduit plug
pre-installed in the PF 1/2 conduit entry on
the side. The screw can be removed and
installed in the back conduit entry. Loosen
the conduit plug setscrew (as shown in
Figure 4) before removing the conduit plug.

Connect the power supply cable (12VDC/24VAC), video output and alarm
output to the proper connectors shown as Figure 5.
The V. Phase adjustment screw is located on the termination board. 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.
5. View Angle Adjustment
The camera can be rotated 360° horizontally, 140°vertically and 60° 3’rd axis
view angles (as shown in Figure 6). Adjust the proper camera view angle as
needed. If a vari-focal lens is used, you may adjust the focus and zoom of
the lens to bring the object in focus. Be sure to loosen the locking screws on
the lens before you make adjustment.

DIPSWITCH FUNCTION
¾BLC (Back Light Compensation)
When BLC is turned on, the AGC, FL 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-light.
The default setting is OFF. For Auto-Iris lens model, the brightness can also be adjusted via the
Iris level control VR.
¾AGC (Automatic Gain Control)
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.
¾FL (Flickerless)
When picture flicker fiercely, turn FL on, then the camera will stabilize the speed of electronic shutter at 1/100(S)(NTSC) or 1/120(S)(PAL)
automatically, and reduce the flicker immediately. The default setting is OFF.
¾IRIS Level Control (For Vari-Focal Lens Model)
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.¾Electronic Shutter (For Fixed Lens Model)
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.
