Allows you to make pan/tilt 3-axis adjustments. For wall or 
ceiling mounting on an unlevel plane, you can rotate the third 
axis to level the view. See 

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.

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.
