Safety Warning
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.
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 -46℃ to 50℃ (-50℉ to 122℉).
3. 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.
4. 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.
5. Heater
Heater elements could be very hot!! Heaters are located inside
the camera housing and will active automatically while the
environment temperature is below 10℃. Do not touch the
heater element while it’s active.
The most technically advanced EHD320 is 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. The extremely EHD320 is unquestionably one of the
world's toughest cameras and is your best choice for vandal resistance.

Installation Instructions
1. Loosen the 4 fix screws on the housing cover by using the attached wrench
(Figure 1). Carefully uncap the housing cover as the direction shown below
(Figure 2), please pay attention not to damage the lens. To remove the
housing cover, push the hinges to the bottom of the bracket, the hinges can
be easily removed from the bracket.

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 3),
remove the camera from the mounting base. Reinstall the camera and the
cable while the base mounting is completed.

Attach the base to the wall or ceiling, fix the base by the 4 setscrews
attached in the accessory pack. The dome is weighted 1.7kg, 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.
Back conduit entry (PF1/2)
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

Side conduit entry (PF1/2)
shown in Figure 5) before removing the
conduit plug.

Caution: To prevent moisture leaking into the housing, apply an
appropriate gasket or sealant around the conduit connection.
4. Re-assemble Camera
1. If mounting EHD320 on the wall, please to aim the “Wall” in line
with the triangle “S” marked on the lead frame. (factory default)
Figure 6-1
2. If mounting EHD320 on the ceiling, please to aim the “Ceiling” in
line with the triangle “S” marked on the lead frame.

Connect the power supply cable (AC24V/DC12V), video output and alarm
output to the proper connectors shown as Figure 7.
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.
6. View Angel Adjustment
The camera can be rotated 360° horizontally, 140° vertical and 60° 3’rd
axis view angles (as shown in Figure 8). Adjust the proper camera view
angel 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 do the adjustments.

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.
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.
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.
FL (Flickerless Function) 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.
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.
IRIS Level Adjustment
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.
IRIS ALC Adjustment
To select light metering method –
Turn the IRIS ALC Adjustment VR counterclockwise for Average
Turn the IRIS ALC Adjustment VR clockwise for Peak Metering.
