SECTION 2: INSTALLATION AND SETUP
Audio in/out wiring schematic
To connect a speaker and/or microphone to the camera:
1. Strip 1/4” of insulation from the microphone and speaker wires and insert them into the terminal
block in the pin locations shown in the terminal block gure above. Note that the common (ground)
leads of the microphone and speaker share the same terminal block pin.
CAUTION
Do not attach a headphone or earphone directly to the camera.
2.7.2 Sensor in (DI) connection
The camera provides one channel for sensor input that can be connected to either a voltage type or relay
type sensor. For voltage type sensors, the camera allows an input voltage range of 0 ~ 24 V DC, with
a 1 V DC threshold (see Specications). The conguration of the sensor input wiring is illustrated in the
following schematics.
CAUTION
Do not exceed the maximum input voltage or the relay switching rate. Refer to the
specications in this manual for more information.
