Adjust the focus position.
Loosen the flange-back lock screw and rotate the flange-back adjustment ring to adjust the
focus position while monitoring the video monitor. When completing the adjustment, tighten
this screw.
Recommended tightening torque: 0.05 N·m {0.5 k

gf·cm}

• When the screw is tightened stronger than the recommended tightening torque, it may

strip the thread or cause focus misalignment.

• When using a fixed-focal lens featuring the focus adjustment, adjust the flange-back

length after setting the lens focus to the FAR end.

• When using a vari-focal lens featuring the focus adjustment, refer to the operating

instructions of the lens in use.

• 24 V AC (WV-CP284)

The recommended cable length and thickness are shown in the table for reference. The
voltage supplied to the power terminals of the camera should be within 19.5 V AC and 28 V
AC.

• 12 V DC (WV-CP284)

Use the formula below to calculate the power cable and power supply. The voltage sup-

plied to the power terminals of the camera should be within 10.8 V DC and 16 V DC.
