The PumaGuard system consists of three main components:

  1. Central Unit

    This unit contains the inference machine which processes the incoming photos from the Trailcam Units. If a Puma was identified, the central unit activates lights and sound through one of the Output units.

  2. Trailcam Unit

    This unit contains a trailcam and a small processing unit. The processing unit monitors the camera for new photos and sends new photos to the Central unit for processing.

  3. Output Unit

    The output unit contains a speaker and lights for scaring the puma away. The speaks and lights are controlled by a small processing unit which gets instructions from the Central unit.

Below a schematic of the setup. Note that there can be multiple Trailcam and Output units.
