Installation and connection

Set the video setting switches on the camera unit
before mounting it.
To set the switches, use a fine-tipped screwdriver.

The maximum connection distance varies with
the type of cable used. Please refer carefully to
the table for each cable during connection.
* Be sure to turn off the power of devices before

connecting cables.

Video signal cables

Connect the coaxial cables (BNC) to the video
signal output connector (BNC).

Installing the Ferrite core
(TK-C210FW only)

In order to reduce the influence to the screen
caused by the noise induced from the cable, wind
both Video signal cable and Input power supply
cable once to the supplied Ferrite core.

DC 12 V or AC 24 V power supply cable

Connect the DC 12 V or the AC 24 V power
supply to the DC 12 V/AC 24 V terminals on the
terminal board. To prevent connection errors or a
cable disconnection, we recommend the use of
lug plates for the connections. The following table
shows the connection distances and connection
cables provided that 2-conductor VVF cables
(vinyl-insulated vinyl sheath cables) are used.

CAUTION:

● If thin cables are used (i.e. with a high

resistance), a significant voltage drop will occur
when the unit is at its maximum power
consumption.
Either use a thick cable to restrict the voltage
drop at the camera side to below 10 %, or place
the power supply near to the camera.
When the voltage is low, the protection circuit
within the camera may be triggered and the
power of the camera may turn off automatically.

● Do not allow input from both a DC 12 V and AC

24 V power supply at the same time.

● When using a DC 12 V power supply, ensure

that the polarities of the cable are correct.

● The AC 24 V power supply should conform to

the following:
U-type: Class 2 only
E-type: Isolated power supply only

Electrical Specifications of Alarm Input
Terminals

(TK-C215V12 only)
● To prevent penetration of noise in the internal

circuitry, apply a non-voltage contact signal to
the ALARM input terminal. Never apply a
voltage.

● Apply an alarm signal for at least 200 ms. If it is

shorter, it is not guaranteed that the signal will
be recognized as an alarm signal.

● Under the alarm status (status when the metal

contact is “make”), select the contact or
connecting wire such that the maximum wire
resistance between the ALARM IN and ALARM
GND is within 150

K.
