5. Detection Ranges – PIR Detection Zones
A passive infrared sensor (PIR sensor) is an electronic sensor that measures infrared (IR) light radiating from objects in its
field of view. PIR Angle refers to the degree that the sensor can sense movement. Cameras that have a large PIR Angle
can detect movement over larger areas and have a better chance of capturing the subject in the center of the frame as
opposed to the edges like some lower quality cameras do. The longer the distance that the camera can sense, the more
area that is detectable and the more opportunities the camera will have to capture that perfect picture.
In Boly cameras, the PIR Angle is slightly smaller than the camera’s field of view angle. This feature is inherent in our
camera designs without reducing the overall possible detection area, due to our patented technology that enhances
increased sensor angles and lengthens trigger distance. By making the PIR Angle slightly less than the camera’s field of
view, we have reduced empty pictures rates and helped assure that the entire subject is captured within the photos and
videos.
With our patented sensor technology, we have increased the camera’s effectiveness over standard PIR cameras to
assure that all detectable motion is captured. Combined with our patented BolyRaw image processing technology, we are
confident that the images captured are of the highest quality that you can display and enjoy for years to come.
