signal lines. The high voltage current should be avoided especially.
Insure the connection stable and credible
The signal and shield lines should be firm and connected credible which avoid false and joint
welding and oxidation.

2.5.2 Video output connections and options

The video output is divided into PAL/NTSC BNC(1.0V
configuration).
When replace the monitor by the computer display, there are some issues to notice.
1 D o not stay in the turn-on state for a long time.
、
2 K eep the computer display normal working by demagnetizing regularly.
、
3 S tay away from the electro magnetic Interference.
、
TV is not a credible replacement as a video output. It demands reducing the use time and control the
power supply and the interference introduced by the nearby equipments strictly. The creepage of low
quality TV can lead to the damage of other equipments.

2.5.3 Audio signal input

Audio port is BNC connection.
The input impedance is high so the tone arm must be active.
The audio signal line should be firm and away from the electro magnetic Interference and connected
credible which avoid false and joint welding and oxidation. The high voltage current should be avoided
especially.

2.5.4 Audio signal output

Commonly the output parameter of DVR audio signal is greater than 200mv 1KΩ(BNC) which can
connect the low impedance earphone and active sound box or other audio output equipments through
power amplifier. If the sound box and the tone arm can not be isolated, howling phenomena is often
existed. There are some methods to deal with the above phenomena.
1 、 Adopt better directional tone arm.
2 Adjust the sound box volume to be under the threshold that produces the howling phenomena.
、
