Audio Connections

The audio signals are transmitted two-way and in sync with the video signals. As a result, you
can connect a speaker or door intercom system at the destination point, for example. The
following specifications should be complied with in all cases.

Network
You can connect the VideoJet X40 SN to a 10/100 Base-T network using a standard UTP
category 5 cable with RJ45 plugs.
CF Slot
You can insert a type I or II CompactFlash card into the Compact Flash slot to enable
recordings to be saved locally. CF cards are the ideal solution for shorter storage times and
temporary recordings, for example alarm recordings or local buffering in the event of network
interruptions.
NOTICE!

You can obtain a list of compatible CF cards from your supplier or directly from Bosch
Security Systems. This list is constantly being updated and extended.
Playing back recordings is also possible using a different VideoJet X40, a VideoJet X10 or a
VideoJet X20.
