transmission between the camera and the connected device.
RS485接口。通过该接口，摄像机可以以半双工的方式通过透明通道与连接的设备互相传递数据。
AUDIO IN/
Audio-in/Audio-out port and audio ground port.

AUDIO OUT/
AUDIO IN/AUDIO OUT为音频输入/输出接口。AUDIO_GND为音频接地接口。
AUDIO_GND
Alarm output port. The value n can be 0 and 1. Each ALARM_OUT and ALARM_REFn form
a group of alarm output. A maximum of two groups are supported. The rated voltage of
an alarm-out device is less than or equal to 30 V DC or 125 v ac, and the rated current id
ALARM_
OUTn/
less than or equal to 200 mA.
ALARM_REFn
告警输出接口，n为0和1。ALARM_OUTn和ALARM_REFn组成一组告警输出，一共两组。告警输
出所驱动设备的额定电压不高于DC 30V或AC125V，且额定电流均不大于200mA。

Alarm-in ground port.
ALARM_GND
告警输入接地接口。
Alarm-in port. The value n can be 0, 1, 2, and 3. Each ALARM_IN and ALARM-GND form a
channel of alarm input. A maximum of four channels of alarm input are supported.
ALARM_INn
告警输入接口，n为0～3之间的整数。ALARM_INn和ALARM_GND组成一路告警输入，一共4
路。

ALARM OUT和ALARM REF组成一组告警输出。告警输出所驱动设备的额定电压不高于DC 30V或
AC125V，且额定电流均不大于200mA。
Alarm input port. There may be multiple alarm input ports. For a given number of ports, n,
they are numbered (for example, ALARM_IN0, ALARM_IN1, ..., ALARM_INn). Each one connects
to the GND connection to form a single alarm input.
告警输入接口。存在多个告警输入线，则采用ALARM_INn表示，n为数字，每条告警线与GND组成一
组告警输入。
Alarm input ground port.
告警输入接地接口。
Audio-in/Audio-out port and audio ground port.
AUDIO IN/AUDIO OUT为音频输入/输出接口。AUDIO GND为音频接地接口。
