Refer to the Important Information on the provided CD-ROM for details about each cable.

IMPORTANT:

󱾀Turn off each system’s power supply (PoE hub or device to supply power to the camera) before

making a connection.

󱾀The 12 V DC power supply shall be insulated from the commercial AC power.

【1】

Connect an Ethernet cable (category 5e or better, straight) to RJ45

(female) network cable.

The maximum cable length is 100 m {328 feet}

IMPORTANT:

󱾀If the procedure for the RJ45 waterproof connector (accessory) part is not correctly followed, the

waterproofing may be compromised. Do not install the camera where the RJ45 waterproof connector is exposed to constant rain or moisture.

󱾀The external dimensions of the Ethernet cable are from ø5 mm {ø3/16 inches} to ø6.5 mm {ø1/4inches}.

󱾀When removing the RJ45 waterproof connector, be sure to loosen the RJ45 waterproof

connector cap first, rotate the RJ45 waterproof connector cover in the direction opposite to the attaching direction, and remove it. (If the RJ45 waterproof connector cover is removed when the “⇦” mark of the RJ45 waterproof connector cover is aligned with the “▶” mark of the RJ45 waterproof jack, the RJ45 waterproof jack may be damaged)

AFirst pass the Ethernet cable through the RJ45

waterproof connector cap (accessory) and then through the RJ45 waterproof connector cover (accessory). Next, use a specialized tool (locally procured) to crimp the RJ45 plug (locally procured) to the end of the Ethernet cable.
