• Current event setup: using the current Audio & Camera setup1 • Case no event: if there were no audio/camera recording • Continuous events: if the audio/camera recorded continuously

1 When trigger events are enabled, it is often impossible to determine the exact size of the recordings. Therefore, the worst case scenario is used to estimate the size information for the used event setup.

11

Audio & Camera Setup

Audio & Camera Setup Interface

Audio & Camera Setup Interface Controls Control / Indicator Description

This check-box enables the periodic recording of audio and camera snapshots.

These controls apply to the periodic recording of audio and camera snapshots. The interval is the duration between periodic recordings, and duration is the duration of the audio and camera snapshots recording period. The “Align with Clock” button enables to align the periodic recording with the clock. Otherwise, it will be aligned with the measurement start-time.

This check-box enables audio and camera snapshots recording triggered by noise exceedance.

This list-box allows selecting the trigger type. “Single Trig” starts the recording at the exceedance time and stops after a specified duration. “Multi Trig” starts the recording at the exceedance time and keeps recording until the noise is below the exceedance level, only then it will stop after a specified duration.

These controls allow entering the exceedance value. Choices are SPL (A, C or Z) and Peak (A, C or Z)

These controls allow setting the pre-trig recording period and the total period duration. Hence, 5s pre-trig and 30s duration means that recording will begin 5 seconds before the exceedance is triggered and will stop recording 25 seconds after the event for a total of 30 seconds.

These controls allow ignoring exceedance if the last exceedance occurred within the last X minutes unless the current exceedance is louder than the last exceedance. This feature is to enable a smart filter to avoid having too much exceedance recordings, when it’s raining for instance.

12

Audio is always recorded during events. The image size is 640x480 (0.3 megapixels)

This List-box allows selecting the audio format, available choices are: • WAV 16 bits 20kHz • WAV 16bits 10kHz • MP3 128kb/s, • MP3 64kb/s • MP3 32kb/s
