Specifications
1 Tip
Unbalanced microphone (with or without electret
power) or line
For audio in, the left channel is used from a stereo signal.
I/O connector
Use the I/O connector with external devices in combination with, for example, motion detection, event triggering, and alarm
notifications. In addition to the 0 V DC reference point and power (DC output), the I/O connector provides the interface to:
Digital input - For connecting devices that can toggle between an open and closed circuit, for example PIR sensors, door/window
contacts, and glass break detectors.
Digital output - For connecting external devices such as relays and LEDs. Connected devices can be activated by the VAPIX®
Application Programming Interface, trough an event or from the product's webpage.

inductive load, e.g., a relay, connect a diode in parallel with the load,
to protect against voltage transients.
