Installation
Caution
To prevent the camera from falling, make sure to attach the supplied wire
rope.
Suitable lens
The lens must be a CS-mount type and the protrusion behind the mounting
surface must be 5.5 mm (
7/32
inch) or less.
Caution
Keep the lens mount cap on the camera when it is not attached the lens.
When you install it into a wall or a ceiling, check that the wall or the ceiling
is strong enough to hold the weight of the camera including the mounting
bracket, and install it without fail. If not, the camera falls down and causes
a serious injury. Also, check if the mounting is not loosened at least once a
year. Make the checking interval short according to use condition.
Performance will depend on the installation environment and the lens
itself. For details, contact your authorized Sony dealer.
Attaching the wire rope
When you install the camera on a ceiling or a high position, be sure to attach the
supplied wire rope to prevent the camera from falling.
Attach the 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 screw.
Caution
Use the supplied screws for installation. If not, the wire rope may not function
properly.
Adjusting the Camera Coverage and Focus
1
Loosen the zoom ring locking screw to adjust the camera shooting
coverage.
2
Tighten the locking screw to fix the zoom.
3
Loosen the focus ring locking screw to adjust the focus.
4
Tighten the locking screw to fix the focus.
5
Press the Easy Focus button on the rear to automatically adjust the
focus.
Note
You may not achieve satisfactory focus with the Easy Focus button due to the
shooting environment.
In this condition, press and hold Easy Focus button for more than 4 seconds to
return to the default flange back position. Then, adjust the focus following
step 3 and 4.
Connection

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.
