The 10-second pre-record feature is repeatedly highlighted as a practical advantage for capturing the start of events. The tradeoff is noticeably higher power draw versus pure motion-trigger recording.
At least one review notes clips can include a second or two before the trigger, but other reviewers still observed occasional missed starts depending on settings and scene activity.
The app offers buffer and clip controls that can help capture more of an event, but actual pre-event coverage depends on the chosen recording and 24/7 capture settings.
Recording options include buffers and adjustable clip length in the app, letting you trade battery for more context. Even with tuning, clips can still skew short compared with always-on wired cameras.
Pre-event coverage is mixed: some reviewers note little-to-no pre-roll on local clips, while others suggest events can be labeled slightly before motion (depending on recording mode).
