Safety Warning  
1. 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.  
2. 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 -46to 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.

Introduction  
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.  
Main Features :

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  
Conduit plug  
shown in Figure 5) before removing the  
Side conduit entry (PF1/2)  
conduit plug.  
Figure 5  
Caution: To prevent moisture leaking into the housing, apply an  
appropriate gasket or sealant around the conduit connection.

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  
Metering.  
Turn the IRIS ALC Adjustment VR clockwise for Peak Metering.
