■ This unit can be connected to external devices such as a camera for video signal input, a
microphone for audio signal input, and an NTSC or PAL monitor for video and audio signal
output.
■ It can be connected to external devices such as an alarm according to the user’s request.
■ It can be connected to a PC through a LAN or Serial connection for remote control.
Caution Caution
– A monitor capable of displaying an NTSC or PAL video signal must be used with
this unit. An ordinary computer monitor cannot be used.
■ SDM-160 is a Multiplexer for NTSC, and SDM-160P is a Multiplexer for PAL.
■ Connect this unit’s video signal input jack to the video signal output jack of SDM-160 and
connect this unit’s video signal output jack to the video signal input jack of SDM-160.
■ Connect the alarm output jack (ALARM OUT) of SDM-160 to this unit’s alarm input jack
(ALARM IN), and connect the VTI jack of SDM-160 to this unit’s trigger output jack
(TRIGGER OUT).
■ Connect both GND terminals together.
■ For details on the functions of SDM-160, please refer to the user’s guide of SDM-160.
Caution Caution
- Be sure to connect the trigger output terminal (TRIGGER OUT) of this unit to
the Multiplexer. Otherwise, a normal recording cannot be made.
(For the connection method, please refer to the user’s guide for the Multiplexer
you want to use.)
- Set up the Multiplexer so that the selection of video signals is controlled by the
Trigger Pulse in when the system’s field recording rate is set from 0.5 ~ 15 FPS
(Fields Per Second) for NTSC signals, or 0.5~12.5 FPS for PAL signals.
(For settings related to the recording field rate, please refer to "(4) PICTURE
RATE" on page 4-7.)
- Only half of a video channel may not be recorded, depending on the type of
multiplexer, when the system’s field recording rate is 30 FPS (for NTSC) or 25
FPS (for PAL). In this case, set the output mode of the multiplexer to Frame-
Mode or adjust the field recording rate of the DVR to 60 FPS (for NTSC) or 50
FPS (for PAL).
