What to know before buying

Listing details to confirm

The listing is inconsistent on image resolution: the title and feature text claim 2K/3MP and the capture field says 1440p, while another field says 1080 Pixels effective resolution, check the selected product details if resolution is decisive. The six-month/180-day battery figure is a manufacturer claim without stated usage conditions, and customer feedback on battery life, detection and connectivity is mixed. The detail field lists motion-only alerts while feature text claims person, vehicle, pet and package detection, verify the detection functions available for this exact model.
