CONNECTING VIDEO SOURCES OR DISPLAYS
Figure 18. Connecting Camera or Monitor
Refer to Figure 18. To connect a camera, plug a standard coaxial cable into the Video In BNC connector on the rear of the NET4001A and the
other end into the camera. You can use any video source (for example, a VCR) with a composite PAL or NTSC output. The input accepts color
or black and white sources and automatically detects whether it is PAL or NTSC. The video input has an internal termination of 75 ohms.
CONNECTING A MONITOR
Refer to Figure 18. To connect a monitor, plug a 75-ohm video cable into the Video Out BNC connector on the rear of the NET4001A being
used as a receiver and the other end into the monitor. This works with any suitable PAL or NTSC monitor. Select PAL or NTSC in the Video
Decoder Settings configuration page.
CONNECTING AUDIO EQUIPMENT
The NET4001A provides an audio channel via the audio in and out jacks.
1. Connect a pre-amplified microphone to the Audio In jack on the transmitter and/or receiver.
2. Connect a loudspeaker to the Audio Out jack on the transmitter and/or receiver.
The audio signals are transmitted bi-directionally and simultaneously with the video signals. This allows control of a loudspeaker or door
intercom system, for example, at the monitored location. Bi-directional audio applies to box-to-box connectors only. MPEG2 should be
selected in order to receive a good audio signal.
