## Overview
IR Dazzler emits continuous IR at 38 kHz to overwhelm night-vision cameras. Runs in hardware with minimal CPU use.
Note: Continuous IR can warm the LED and draw more current. Stop when not in use.
## Use from the UI
- Open the Infrared view.
- Select IR Dazzler. A popup appears and the LED begins emitting.
- To stop, press the on-screen Stop button or press any enter/confirm input (touch, joystick, encoder, keyboard) while the popup is active.
The dazzler also stops automatically when you leave the Infrared view or run the global stop command.
## Use from the CLI
ir dazzler # start
ir dazzler stop # stop
The stop command also halts any active dazzler session.
## Compatibility
- Requires a board built with IR transmit hardware; the feature is hidden when CONFIG_HAS_INFRARED is off.
- Uses the configured IR LED pin (CONFIG_INFRARED_LED_PIN) with a 38 kHz carrier and high duty cycle flood.
