A camera trap is a remotely activated camera that is equipped either with a motion sensor, an infrared sensor, or a light beam that works as a trigger. Camera trapping is a method for capturing wild animals on film when researchers are not present, and has been used in ecological research for decades.
Camera traps are used to capture images of animals in the wild with as little human interference as possible.
The popularity and efficiency of this method of field observation, allowed advancements in the quality of camera equipment, improving results.
Nowadays Camera trapping is a fundamental tool for researchers, allowing to collect information impossible to get with the human presence.
