Built-in
Microphone
Features a built-in microphone mounted on the front of the
camera. The camera also has a connection for an external
microphone on the rear. Connecting an external microphone
disables the built-in microphone.
Passive
Infrared (PIR)
Sensor
Alerts you to objects up to 5 M (16.4 feet) away based on
thermal detection.
CAUTION
As with all PIR motion sensors, there are certain
factors that impact detection range and reliability. PIR sensors
rely on changes in heat to detect motion, so be aware of the
following factors: rapid environmental changes, direct
sunlight, direct wind from a heater or air conditioner,
fireplaces, automobiles, or industrial equipment. Also note
that different types of glass may or may not allow infrared
light to pass through. If you want to detect thermal activity
through glass, it is recommended that you test it in your
particular environment.
