Video In (1-4)
Four video inputs and four video loop outputs are provided for video source connections using
standard BNC connectors. The video inputs accept monochrome or color composite video
signals. The looping video outputs (Loop 1-4), provided for each camera are used to loop
the video signal to other equipment.
NOTE: The BNCs on the DVR are self-terminating. Do not connect a cable to the
Loop connector unless it is connected to a video device because this will defeat the
termination.
Video Out
A composite video output is provided on the Video Out BNC for connection to a B/W or color
video monitor. The SVHS output (mini-DIN connector) is provided for SVHS monitor
connection. Both Video Outs can be used at the same time.
Audio In
One audio input is provided on the Audio In RCA connector. The input only accepts the
line-level signal, so an external pre-amplifier is required to connect a microphone.
Audio Out
One mono audio output(line-level) is provided on the Audio Out RCA connector. This
output allows monitoring of live audio signals or audio signal during playback. An external
audio amplifier is required.
Network Port
The Network Port is a RJ-45 port that supports 10/100 Mbps Ethernet connections.
Modem Port
The Modem Port is a RJ-11 port that supports a telephone line connection.
Text In/PTZ Port
The Text In/PTZ Port is used for either text input or PTZ control. When using for the Text In
port, it supports standard RS-232C ASCII text input on a DB-9P connector. This text source
may be from POS devices, cash registers, ATMs, access control systems, or other sources that
output asynchronous ASCII information. When controlling the PTZ camera via RS485 input,
the additional RS232 to RS485 converter is required.
