Peripherals

Configure audio, alarm input, and access-control outputs on the Peripherals page.

I/O Control​

  • Mic Input: enable the microphone for monitoring, talk-back, or app audio capture.
  • Speaker Output: enable the speaker for talk-back or app audio.
  • Alarm Input: alarm input switch. The current firmware does not report it to the event bus/API; use external wiring for linkage.
  • Alarm Input Level: High / Low trigger level; not effective in the current firmware.
  • Wiegand CH0 / CH1: two outputs for access-control controllers; not for card readers.

NE503 provides one alarm-input channel. Follow the hardware documentation for wiring and power requirements.

Linkage​

  • Two-way talk: enable Mic Input and Speaker Output, then use Talk on Media.
  • AI events: an app or business system subscribes to events and drives an external relay; the platform has no built-in automatic linkage.
