System adopts standard RJ45 network port to input audio/video data.
3.5.1 Connecting Video Output
Video output includes a
T
CVBS(PAL/NTSC BNC （ 1.0VP- P ， 75 Ω ） output and a VGA output.
System supports CVBS and VGA output at the same time.
When you are using pc-type monitor to replace the monitor, please pay attention to the following
points:
To defer aging, do not allow the pc monitor to run for a long time.
Regular demagnetization will keep device maintain proper status.
Keep it away from strong electromagnetic interference devices.
Using TV as video output device is not a reliable substitution method. You also need to reduce the
working hour and control the interference from power supply and other devices. The low quality
TV may result in device damage.
Note:
You need a switch cable if you want to use VGA output.
3.5.2 Audio Output
The audio output signal parameter is usually over 200mv 1K Ω (BNC). It can directly connect to
low impedance earphone, active sound box or amplifier-drive audio output device.
If the sound box and the pick-up cannot be separated spatially, it is easy to arouse squeaking. In
this case you can adopt the following measures:
Use better sound pick-up with better directing property.
Reduce the volume of the sound box.
Using more sound-absorbing materials in decoration can reduce voice echo and improve
acoustics environment.
Adjust the layout to reduce happening of the squeaking.
Please refer to Figure 3-6 for 4-pin aviation port cable information. It is for audio and video output.
