How the O3 Senses Occupancy

The O3 uses a combination of PIR motion sensing and microphone audio detection to determine when room occupancy changes.

How It Works

A state change from unoccupied to occupied is triggered when motion is detected in the room, or by a combination of motion and sound. Sound alone does not trigger a state change.

When either motion or sound is detected in the room, the occupancy state is extended. This sound level must be above the baseline audio level that the O3 has previously established. In addition, new sounds that fall outside of the Occupancy Audio Retrigger Period value are not allowed to extend the occupancy state. This feature reduces artificial extension of the occupancy state due to background noise.

Frequently Asked Questions

What is the motion sensing range?

Motion sensing area of influence is the area under the O3 with a diameter approximately equal to 2 times the mounting height.

Does the O3 record audio or voice conversations?

The O3 does not record audio. It reads audio levels in decibels and uses this as an input to determine if a room is occupied. However, audio is not recorded nor is it translated in any way. This limitation is intentional for privacy reasons.

Does the O3 have glass break detection?

No, the audio analysis capabilities of the O3 cannot detect glass breaks.

Does the O3 have gunshot detection?

No, the audio analysis capabilities of the O3 cannot detect gunshots.
