Known solutions

Camera IR emitters not turning on

Setting a specific camera resolution

Some IR cameras only work at specific resolutions. Try running the following command: (replace DEVICE_PATH with the path found under device_path in sudo howdy config)

v4l2-ctl -d DEVICE_PATH --list-formats-ext

This command should list all available formats. For example, my cameras 340 by 340 resolution option is reported liek this:

Size: Discrete 340x340

Experiment with these values by setting frame_width and frame_height in sudo howdy config.
