VideoJet 400
Connections
Cameras A maximum of four video sources can be connected to the
VideoJet 400
. Suitable devices are all cameras and other video
sources which generate a PAL or NTSC standard signal. The con-
trol cabinet version of the
VideoJet 400
also has a monitor out-
put which permits the connection of a monitor suitable for PAL or
NTSC standard video signals if the device is also to be used as a
receiver.
)
Connect the cameras or other video sources to the BNC jacks
VIDEO 1 to VIDEO 4 using a video cable (75 Ohm, BNC connec-
tor).
)
Set the DIP switches to position 75 OHM ON (down) to terminate
the inputs at which the video signal is not lopped through (e.g. with
a T-piece).
)
If necessary, connect a video monitor to the BNC jack VIDEO OUT
of the control cabinet device using a video cable (75 Ohm, BNC
connector).
Network
connection You can connect the VideoJet 400 either directly or via a hub to
a 10/100 BASE-T network. Use a standard cable UTP Category 5
with RJ45 connectors for this connection.
)
Connect the network cable to the ETHERNET jack.
Alarm inputs The four metallically isolated alarm inputs serve for the connection
of external alarm triggers, e.g. door contacts or sensors. If config-
ured accordingly, an alarm trigger can, for example, set up an auto-
matic connection between
VideoJet
and the remote station.
Connection INPUT 5 serves as a master alarm. If necessary, this
contact allows all the alarm triggers (contacts and video sensors) to
be activated or barred, e.g. by means of a key-operated switch.
