MOTION SENSOR

The motion sensor on the SkyBell Trim Plus contains a Fresnel lens.
This is a flat lens made of a number of concentric rings, to reduce spherical
aberration. Spherical aberration is a loss of definition in the image arising
from the surface geometry of a spherical mirror or lens. This enhances the
accuracy of motion detection, which will improve your overall SkyBell
experience.

The SkyBell device uses a PIR sensor (passive infrared sensor), which
is an electronic sensor that measures infrared light radiating in the field
of view; think flood lights or motion detectors for your alarm system.

When the PIR sensor senses activity (meets a certain threshold) and
is activated, it immediately turns the camera on and starts to record
directly to the device. This activation triggers an initial motion event. The
SkyBell continues monitoring this activity energy from the PIR sensor and
when meeting a more stringent threshold, it sends a notification to the
phone. If the notification is answered, the SkyBell records for as long as the
