BX2
The unit can be connected to a standard 10/100-baseT Ethernet network and using the viewing application
offers full control of the unit from a remote location.
Network connection
Refer to the Network Options in the Conguration section for full details on how to congure the units IP
address.
To connect the unit to a network you will need the following items:
• One RJ-45 network cable (CAT5 or equivalent).
• A static or DHCP IP address and Subnet mask (if accessed from beyond the LAN, a Default gateway
IP address will also be needed. Consult the network administrator for advice).
Connecting Audio Devices
The unit supports the option to record audio alongside the recorded video images. The audio can then be
played back in conjunction with the video locally on the monitor output or via the network connection using
the viewing software.
Connecting a pre amp
BX2 can record and playback a single stream of audio linked to camera 1. There are two audio input ports: MIC
IN and LINE IN, and an audio output: LINE OUT.
Where additional microphone gain and/or adjustable gain is required, an external microphone pre-amplier
with adjustable gain is recommended. A microphone pre-amplier will provide a line level 1V pk-pk signal that
can be connected to the RCA socket labelled LINE IN on the BX2.
Connecting the AUDIO OUT to an amplier
Connect the RCA socket labelled LINE IN to an external amplier or powered loudspeakers.
The line level input has the following specication:
Line IN 47kΩ input impedance, 1V pk-pk
Recording audio
Once the pre-amplier is connected to the BX2, the option to record audio should be enabled in the ‘System
Options’ menu.
It is advised that you test the quality of audio playback, it may be necessary to increase the gain.
As the audio is linked to camera 1 recording, it is required that camera 1 be viewed, either in a full screen or in a
quad view during playback to hear the audio.
