Peripherals

The Peripherals page manages NE503's external hardware interfaces: audio, alarm, and access control. Each item is configured as a toggle or option.

I/O Control​

Mic Input / Speaker Output (Audio)​

  • Mic Input: enable the device microphone for monitoring, talk-back, or app audio capture on the Media page.
  • Speaker Output: enable the device speaker for talk-back or app-generated audio.

Alarm Input​

  • Alarm Input: enable alarm input detection.
  • Alarm Input Level: choose the trigger level — High or Low — the external signal level considered "triggered."

NE503 exposes 1 alarm input channel.

Wiegand (Access Control)​

  • Wiegand CH0 / CH1: two Wiegand channels for connecting Wiegand-protocol access-control readers.

Once enabled, card-swipe data from the reader can be emitted to the Event Bus for apps or external systems, enabling access-control linkage.

Linkage with Other Features​

Peripherals are not isolated. Common linkage patterns:

ScenarioPath
AI detects a target → trigger alarm output / access controlApp receives AI events via Event Bus → controls IO
Alarm input triggers → push event to a business systemAlarm IN signal → Event Bus → MQTT / HTTP
