E-6
Ⅲ A new DSP (Digital Signal Processor)
features a Extended Dynamic Range
(ExDR) and enables to shoot both bright
and dark locations.
Ⅲ The use of a new CCD with a SENSE UP
(X32) function realized the minimum
luminous flux density for subject of 0.6 lx
(F1.2, 50%, AGC 20dB) and 0.019 lx (at
slow shutter).
Ⅲ A motion detector function detects the
motion inside an image and emits alarm
signals.
Ⅲ The equipped Y/C terminals and RS-
422A/RS-485 terminals allow intended
compatibility with diversified systems.
Ⅲ Electronic zoom
The 10x electronic zoom allows
monitoring in far greater detail.
Features
Ⅲ Before starting an important recording,
be sure to perform a test recording in
order to confirm that a normal
recording is possible.
Ⅲ We do not accept liability for the loss of
a recording in the case of it becoming
impossible to record due to a problem
in the video camera, VCR or video tape.
Ⅲ We do not accept liability for any
damage to the camera in cases where
it is dropped because of bad installation
due to failure to observe the installation
instructions correctly. Please be careful
when installing the camera.
Ⅲ The motion detector is not a feature
which prevents theft, fire, etc. Even if
an accident should occur resulting in
damage, we do not accept any liability.

● To save energy, when it is not being used
turn the system’s power off.
● This camera has been designed for indoor
use. When you use it outdoors, be sure
to use a housing or the like.
● Do not install or use the camera in the
following places.
• In a place exposed to rain or moisture.
• In a place with vapor or oil soot, for
example in a kitchen.
• When the ambient temperature rises
above or falls below the acceptable
range (from –10°C to 50°C).
• Near a source of radiation, X-rays,
strong radio waves or magnetism.
• In a place subject to vibration.
• In a place with excessive dirt.
● If this camera and the cables connected
to this camera are used where there are
strong electromagnetic waves or where
there is magnetism present, for example
near a radio or TV transmitter, power
transformer or an electric motor, the picture
may produce noise and the colours may
be affected.
● This camera incorporates an AGC circuit.
As a result, when it is used under low light
conditions, the camera sensitivity is
automatically boosted and the picture may
look uneven. However, this is not a
malfunction.
● While the AGC is activated, if a transceiver
which causes strong electromagnetic wave
is at close distance, the picture might suffer
from beat.
So please use the camera more than three
meters from such transceivers.
● When this camera is used in the ATW
mode, the recorded colours may be slightly
different from the actual colours due to the
operational principles of the auto-tracking
white balance circuit. However, this is not
a malfunction.
Operating Precautions
● If a high-intensity object (such as a lamp)
is shot, the image on the screen may have
vertical lines (smear) or blur (blooming)
at its periphery. This is a characteristic of
the CCD, and is not a defect.
● Observe the following when carrying out
camera maintenance.
•Turn the power OFF before proceeding
to carry out maintenance.
If it is contaminated seriously, clean the
contaminated part with a cloth (or a
tissue) which has been soaked in a
solution of water and a neutral detergent.
● The unit is to be powered by a DC 12 V or
an AC 24 V power supply. (TK-C1480BE)
The AC 24 V power supply should conform
to the following: Isolated power supply only
TK-C1481BEG Connect the power cable
to the commercial power supply of 230V.
● Caution for operating the video iris lens.
If the video iris lens is set to an extremely
low level, a malfunction – such as the
hunting phenomenon where the iris opens
and closes involuntary – can occur.
In such a case, first set the “LEVEL”
potentiometer on the lens to the H position
(iris open), and then adjust it to an optimum
level.
● The cable stopper on the terminal block
can come off sometimes. Therefore, be
sure to take enough time and fix the cable
securely.
● When a highly bright subject is shot,
sometimes undulations can be observed
on the vertical lines of the subject.
However, this phenomenon is peculiar to
the unit and is not a sign of malfunction.
● The beat may sometimes appear on the
screen if gain is raised when the line lock
is in use, but the phenomenon takes place
due to the fluctuation of power frequency
and is not a malfunction.
