2.4.3 Audio Talk Input Connection
It adopts BNC port.
2.4.4 Video Output Device and Connection
XP101VD adopts four output sets. VG A, HDMI and BNC a set; BNC(1.0VP-P
,
75
Ω
).
Here we recommend the industry monitor to be the output device of the decoder. It has
the following advantages:
The industry monitor is suitable for long time surveillance. The pc monitor cannot run
for such a long time. It is easy to be aging, damage or burn down.
Industry monitor has stronger vivid and colorful video.
Industry monitor can be used in many complicated environments and has strong
anti-interference capability. It is more stable.
Please note, using TV as video output device is not a reliable substitution method. You
need to reduce the working hours and control the interference from power supply and
other devices. The risk of short circuit problem resulting from low quality TV may cause
damage to other devices.
2.4.5 Audio Output
The audio output parameter of NVS is 200mv 1K
Ω
(BNC), it can connect directly 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:
