communications. However, there is no guarantee that interference will not occur in a
particular installation. If this equipment does cause harmful interference to radio or
television reception, which can be determined by turning the equipment off and on, the user
is encouraged to try to correct the interference by one or more of the following measures.
CAUTION;
ANY CHANGES OR MODIFICATIONS NOT EXPRESSLY APPROVED BY THE PART
RESPONSIBLE FOR COMPLIANCE COULD VOID THE USERS AUTHORITY TO
OPERATE THE EQUIPMENT.

E-1
1. Handling precautions
•Do not install the camera in a water-splashed or highly humid environment.
•Do not use the camera where the ambient temperature drops below -10°C or
rises above +50°C. The images and component parts may be adversely affected
or the camera may not function correctly.
•Never open the camera case because there are precision electrical and electronic
components inside and an accident may result.
•Do not put anything metallic or any other foreign substances through the vent, as
a fire or electric shock may result.
•Be sure to turn off the power before installing or making connections.
•Do not install the camera in places exposed to heat, vibrations and shocks.
•Be careful not to drop or give a strong shock to the camera while transporting it.
•Do not touch the image sensor.
•Do not orientate the camera directly towards the sun.
•Some types of lenses may hunt in adverse light conditions. In such cases please
re-adjust the lens in line with the instructions in the manual.
* Because of the characteristics of the digital image device, images may look
unnatural at high temperatures, this does not mean the camera is faulty.
2. General
This color camera is provided with a High performance 1/2-inch 380,000 pixel
interline transfer CCD sensor with on-chip-micro lens technology. The camera
features a highly sensitive and wide spectral response with high resolution, and is
equipped with true Day/Night function, intelligent back-light compensation by which
you can achieve proper Back Light Compensation, Automatic iris control, Phase
adjustable AC line lock or Crystal controlled internal sync lock system, Various
modes of convenient Automatic white balancing, Optimum monitor output selection
to have best suited display quality for either CRT or LCD monitors, camera setup
and control is also possible locally on the camera rear panel, or remotely via I-
LAN(*) remote software control over RS-485 link and this setup data is stored in
the built-in non-volatile memory. The camera is best suited for general surveillance
purposes, from single camera operation to large scale integrated systems for visual
information management.
* I-LAN: Ikegami security surveillance system control software for RS-485.
Refer to the Section 5-4-10 for Remote control and RS-485.

3. Features
(1) Very High Sensitive TV Reproduction
This high sensitivity camera with high performance 1/2" CCD is employs an
Electrnonic Sensitivity Increase Facility with an optimum Automatic Sensitivity
Control function that allows to reproduce color picture under very low lighting
condition of 0.005 lux.
The built-in electronic sensitivity increase function raises up to 32 times a
sensitivity. On top of that, a True Day/Night Function is also provided and it is
very useful to shoot moving objects under dim lit condition without un-necessary
lag.
(2) Day/Night change-over function
High-quality color images can be captured by day, or when ample light is
reflected from objects. When the light falls, or only minimal light is reflected
from objects, the built-in moving IR filter system activates to provide
monochrome pictures due to higher sensitivity. This reliable true Day/Night
change over function results in a high resolution monochrome picture of 570TVL
even under very low light conditions down to 0.015 lux minimum scene
illumination.
The change over thresh-hold can be either set manually or preset for auto
operation from the cameras rear panel control or, remotely controlled by I-LAN
software over RS-485 link. This Day/Night change-over system provides for
high quality images without lag or streaking to be generated around the clock.
The camera can also be linked with external sensors resulting in effective
alarm system operation.
(3) High-quality picture and high resolution
The camera is designed for smear-free imaging and low noise. The DSP (Digital
Signal Processor) effectively enhances details, which achieves crisp and sharp
images with a high signal-to-noise ratio. The high performance results in a
horizontal resolution of 540 TVL in color and of 570 TVL in monochrome.

E-3
(4) High performance, High Sensitivity and Low Vertical Smear
The latest interline transfer CCD with on-chip-micro lens technology provides
a wider spectral response from the visible to invisible near infra-red, for high
quality, effective picture reproduction from brightly to dimly lit areas. And the
improved DSP, Digital Signal Processor, permits good signal-to-noise ratio of
52dB with good performance of -126 dB vertical pixel overload protection known
as vertical smear that occurs with intense strong light sources.
(5) Intelligent Back Light Compensation
Well-designed BLC, back light compensation, facility is provided which can
assign a compensation area for back light compensation to have an optimum
balanced clear picture reproduction, by the rear control panel switches, or
remotely via Link.
(6) Two-way automatic iris control
This function is available to switch between Video type iris lens and DC type
iris lens. In other words, almost all types of automatic iris CCTV lenses can be
used.
(7) Automatic white balance
Thanks to the automatic tracking white balance control (ATW), the white balance
adjusts itself no matter how great the subject's color temperature fluctuates.
The ICD-879 provides various useful white balancing functions to meet the
most testing of users requirements resulting in full time automatic color balance,
extended spectrum range balancing (ATW-1 and ATW-2), normal one-touch
white balance and manual balancing by individual R and B gain controls.
(8) AES, Automatic Electronic Shutter
A smooth control to compensate sensitivity variation with an electronically
controlled Auto-shutter, that gives a control range of 1600 to 1 range is employed
to assure a constant optimum picture reproduction.
This AES function gives an acceptable reproduction capability, equivalent to
F1.4 to F50 Iris Control range, even with fixed Iris lenses.

E-4
(9) Privacy Masking Function
The ICD-879 comes equipped with privacy masking, which covers sensitive
areas in the screen that need to remain unseen. You can assign a maximum of
8 zones with minimum 8 pixel square sized area to hide with this masking
function for a pin-point accuracy by the rear panel control switches, or remotely
over RS-485 link. The RCU-801 remote setup and control unit can perform the
same function.
(10)Lens flange back focus adjustment
An easy adjustment can be done by a rotating disk mechanism and convenient
side access port-side Lock screw. This may be useful when changing lens
from single focal lens, vari-focal lens, long focal lens, or zoom lenses, or vice
versa.
(11)Optimum Monitor Output Select function
The optimum picture quality can be obtained with this unique function for CR
or LCD monitors. Sometimes, LCD, Liquid Crystal display type, Flat Screen
Monitor with digital process function shows different display reproduction
characteristics and you may choose this output selection to have the best
pictures on the monitor screen.
(12)Remote or Local camera setup and parameter memory function
ICD-879 series camera comes equipped with micro-chip controlled camera
setup and memory function as a standard provision. Camera setup can be
easily done locally with control switches on the camera rear panel using OSD,
On Screen Display, or remotely by I-LAN, Ikegami's camera control software
over RS-485 link. In addition, an optional remote setup and control unit, such
as the RCU-801 can be used for this purpose via coaxial video cable connection.
(13)Focus EZ function
The auto iris lens aperture will be kept open. Even in broad daylight, the focus
is readily adjustable no matter how much the depth of field is.
