The flash is an important part of the trail camera. The flash allows you to capture those cryptic, rare and often nocturnal species of animals. There are various types of flash to choose from, each with its own advantages and disadvantages. Therefore, it is important to understand this before selecting a camera trap, but also when placing the camera in the field. At the moment we can roughly distinguish three different types of flash: the white flash (LED or Xenon), the visible infrared flash (low glow, red flash) and the invisible infrared flash (no glow, black flash).
