When replace the monitor by the computer display, there are some issues to be noticed.
1
、
Do not stay in the turn-on state for a long time.
2
、
Keep the computer display normal working by demagnetizing regularly.
3
、
Stay away from the electronic 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. Low quality TV can lead
to the damage of other equipments.
2.3.3 Audio signal input:
Connect the microphone with audio input interface on IP cameras. Then turn the IP camera’ audio
function on NVR.
2.3.4 Audio signal output
Commonly NVR audio signal is greater than 200mv 1KΩ(BNC) which can connect the low
impedance earphone and active sound box or other audio equipments through power amplifier.
2.4 Alarm input and output connections:
１、
Alarm input:
A. Alarm input is “grounding” alarm input.
B. Alarm input demand is the grounding voltage signal.
C. When the alarm is connected with two NVRS or connected with NVR or other equipments, it
should be isolated by relay.
２、
Alarm output:
Alarm output cannot be connected with high-power load(no more than 1A).When forming the loop, it
must prevent the big electronic current from relay damage. Use the contact isolator when there is a
high-power load
３、
PTZ decoder connections :
A. The grounding of the PTZ decoder and NVR must be shared otherwise the common-mode
voltage will lead to the PTZ control failure. The shielded twisted pair is recommended.
B. Avoid the entrance of high voltage. Make the layout reasonably. Take precaution from the
