PIR sensors, also known as motion sensors, are used in trail cameras to detect movement in front of the camera. Every trail camera will have one or more PIR sensors. These sensors are integral to the design of every trail camera and will directly impact each camera’s performance.
In addition to the PIR sensors themselves, many trail cameras will also have adjustable settings for the sensor(s). This allows you to get optimal performance from the camera regardless of the environment you have the camera monitoring.
In this article, we will explain what a PIR sensor is and how they work. We will also explain what to look for from a PIR sensor when buying a trail camera as well as talk about the adjustable settings you might find for a trail camera’s motion sensor(s). Finally, we will talk about some tips to get the most out of your camera’s PIR sensors.
