(1) Adopt better directional tone arm.
(2) Adjust the sound box volume to be under the threshold that produces the
howling phenomena.
(3) Use fitment materials that absorb the sound to reduce reflection of the
sound.
(4) Adjust the layout of the sound box and the tone arm.
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 XVR or connected with XVR and
other equipment, it should be isolated by relay.
(2) Alarm Output
Alarm output cannot be connected with high-power load(no more than1A)
When forming the output loop it must prevent the big 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 XVR 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 thunder.
C. In the outlying end connect 120
Ω
resistance paralleled to reduce the
inflection and insure the signal quality.
D. the 485 AB lines of XVR cannot connected with other 485 output
equipment paralleled.
E. The voltage between the AB lines of the decoder must be less than 5V.
(4) Front e Equipment g Grounding Note
Bad grounding can lead to the burnout of the chip.
(5) Alarm Input Type Unlimited
The XVR alarm output port is constant opening type.
