Connecting Cables/ 连接线缆
(Optional) Connect the audio cable, alarm cable, and RS485 cable. To connect a camera to peripheral devices
5
such as a RS485 vehicle detector, radar, or a traffic light reader, connect the RS485 cables of the peripheral
device to the RS485 interfaces of the camera. Ensure that a positive cable is connected to a positive interface
and a negative cable is connected to a negative interface. For I/O vehicle loop detector, its output and input
cables correspond to the TRIG_IN and GND interfaces of camera respectively.
（可选）连接音频线缆、告警线缆、RS485 线缆。摄像机的 RS485 接口可通过连接 RS485 车检器、雷达或红绿灯检测
的 RS485 线，（正极接正极线、负极接负极线），来与这类外设相连。对于 IO 线圈车检器，其输出 / 输入线分别接入摄
像机的触发输入接口（即 TRIG_IN）和 GND 接口即可。
It is recommended that twisted pair cables be used as alarm cables. The diameter of the cable core ranges
from 22 AWG to 28 AWG. The impedance of the entire cable is less than or equal to 100 ohms.
告警线缆建议使用双绞线，线芯的线径为 22AWG ～ 28AWG，整条线路的阻抗≤ 100Ω。
The following figure shows the port distribution.
各端口的位置分布，可参考下图。
CAUTION/ 注意
Before connecting any cables, ensure
that the power is disconnected.
所有线缆连接的操作必须在完全断电的情况
下进行，禁止任何带电的安装。
