Day/Night surveillance

When the light is low, the camera pictures can be switched automatically to black and white pictures.

Electronic zoom

The 10x electronic zoom allows monitoring in far greater detail.

Operating Precautions

●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 transceiver which causes strong electromagnetic wave is at close distance, 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.

●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-C1430E) The AC 24 V power supply should conform to the following: Isolated power supply only

TK-C1431EG: Connect the power cable to the commercial power supply of 220V – 240V.

●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 in voluntary – 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. ( page 20)

●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.

●You may hear some noise when the screen is switched between the colour and the black and white mode, because the optical filter moves. Also, black vertical bands will appear on the screen.

●Set the Iris Selector switch to VIDEO to use the manual lens.
