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.
1
Secure the wire rope to the junction box on the ceiling.
Use a screw to match the screw hole of your junction box (not supplied).
2
Secure 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
1
Select the camera operation mode to match the video monitor in use
with the VIDEO OUT selector.
2
Set 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
1
Remove the screw.
2
Pull 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 V
24 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:
