I’m a big fan of Arlo but ultimately when it really mattered I now have no footage of what has happened and we bought the package last year following a robbery. My question is how much is happening day today at that isn’t being recorded?
How the subject approached the camera could make all the difference. Slow motion directly at the camera may not have triggered a recording. WHat's you motion sensitivity set to in your modes and rules? Have you increased it from the default setting? A screenshot of the camera view may be useful.
