Camera
I. General
The new EI220 series camera features a high performance, Standard
resolution 1/3" color CCD processor and built-in vari-focal lens which
provides excellent picture quality, flexibility and cost savings. A mounting
bracket is included with every EI series camera making it one of the most
complete and easy to install camera packages on the market. It's no wonder
why EverFocus is quickly becoming the first choice in CCTV.
II. Precautions
• Do not expose the camera to humidity and dust. If the camera is
mounted outdoor, a camera housing is required.
• Do not disassemble it or place it on an unstable base.
• 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
camera lens and CCD sensor.
• Never face the camera toward the sun.
• Use proper power source otherwise the camera will not function
correctly.
III. Installation Instructions
1. 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 at camera end.
2. Plug the power cord to the outlet. Power indicator LED should light
if the power source is properly connected.
3.. Remove the lens cover cap from the top of the camera for adjusting
the vari-focal lens
4. Once the image appears on the monitor, adjust the focus and
diaphragm of the lens to obtain the best picture.
5. If the subject is not in focus when adjusting focus of the lens, do
back focus adjustment as following:
i. Set the focus ring of the lens to infinity position.
ii. Take picture of subject at a distance more than 20m
away from the camera.
iii. Loosen the lens mount fixing screw located at
bottom of the front panel by using the L wrench.

IV. Using Special Features
~ Lens Adjustment
You may adjust the focus and zoom of the lens to bring the object in focus.
This lens has two focal distance. The change of Tele/Wide can bedone with
zooming. In case you want to make focus at an optional between Tele/Wide you must
re-adjust focusing once again.
~ Back Light Compensation
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
