4. 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.
