Siren loudness (if built-in)

The integrated siren can be activated remotely from the Arlo app, providing a loud deterrent to unwanted visitors or prowling animals and adding an extra layer of security beyond basic motion alerts and recording.

A built-in siren can be triggered from the app or automations to add an audible deterrent at the front door, with adjustable volume that gets quite loud, though some reviewers feel it can be a more aggressive warning than necessary for casual visitors.
