Detection range was a standout, with reviewers reporting reliable detection or lock-on performance at roughly 150 feet.
Pros: Detection range, Recording start-time lag
Cons: ONVIF/RTSP support, HomeKit integration
Detection and detail range were strong in test evidence, including reliable person detection and clear distant yard coverage.
Pros: Cloud storage plan value, Dual-band (2.4/5GHz) performance
Cons: HomeKit integration, ONVIF/RTSP support
Detection range was strong enough to catch movement around 40 feet away and even distant street activity, though that sensitivity required tuning.
Pros: Low-light performance, Color accuracy
Cons: Speaker volume, Frame rate
Detection range was described as solid at closer distances and still usable around 20 feet, with accuracy declining farther away.
Pros: Cloud storage plan value, Weather resistance rating (IP code)
Cons: Recording start-time lag, Pre-event recording length
Detection range earns mixed feedback: long-distance detection can work well, but side and rear blind spots limit coverage in some installations.
Pros: Cloud storage plan value, Power options (solar panel)
Cons: HomeKit integration, IFTTT/automation compatibility
