Installation

Caution

Request for an expert to install it to the ceiling.

Attaching the fall-prevention wire rope 

When you install the camera on a ceiling or a high position, be sure to attach the supplied fall-prevention wire rope to prevent the camera from falling.

Attach the fall-prevention wire rope to the screw hole on the rear of the camera, as in the illustration.

Note

Take care not to short-circuit the power terminal or the cable with the wire rope when you attach it.

1Secure the wire rope to the junction box on the ceiling.Use a screw to match the screw hole of your junction box (not supplied).

2Secure the wire rope to the wire rope mounting screw hole on the rear of the camera using the supplied shoulder screw.

Caution

Use the supplied screws for installation. If not, the wire rope may not function properly.

Focus Assist Function 

1Select the camera operation mode to match the video monitor in use with the VIDEO OUT selector.

2Set the iris to open with the IRIS selector.

The IRIS OPEN indicator and the focus assist indicator appear on the monitor screen.

The length of bar varies according to the degree of focus adjustment. Bar indicates the peak hold value.

3 Turn the focus ring until bar reaches the peak hold value .
Release the lens connector	

1Remove the screw.

2Pull out the lens connector cover as shown to release the lens connector and then tighten the screw.

Connection

Connecting to the Network 

Connect the LAN cable of the camera to a router or hub in the network using the network cable (straight, not supplied).

To connect to a computer

Connect the LAN cable of the camera to the network connector of a computer using the network cable (cross, not supplied).

Connecting the Power Source

There are three ways to supply power to this camera, as follows.12 V DC24 V ACPower supply equipment pursuant to IEEE802.3af (PoE* system)

*PoE means Power over Ethernet.

Note

If the power is supplied from the power input cable and LAN cable at the same time, the power from the LAN cable has priority over the other.

Connecting to 12 V DC or 24 V AC source

Connect the power input cable of the camera to a 12 V DC or 24 V AC source.

Use a 12 V DC or 24 V AC source isolated from 100 to 240 V AC. The acceptable voltage ranges for each are as follows.

12 V DC: 10.8 V to 13.2 V24 V AC: 21.6 V to 26.4 VUse UL cable (VW-1 style 1007) for these connections.

Connecting to the power supply equipment pursuant to IEEE802.3af

The power supply equipment pursuant to IEEE802.3af supplies the power through the LAN cable. For details, refer to the Instruction Manual of the equipment.

Connecting the I/O Cable

Connect the wires of the I/O cable as follows:
