What to know before buying
Listing details to confirm
The listing details are inconsistent: its title and feature content claim 3K and 9 MP, the video-resolution detail is only “/”, and a separate answer specifies 3072 × 3072. Power information also conflicts: the detail table says 24 Volts and batteries required, while the product content says wired-only operation from existing 16–24 VAC doorbell wiring and describes a built-in battery for power-cut backup. Confirm the exact power requirements and resolution for the selected listing before buying.

Aggregate ratings lean positive, with most ratings in the five-star category, but a portion are one-star. The sample is small and no written customer feedback is supplied, so the ratings do not establish specific strengths, faults or the reasons behind opinions. Buyers should weigh that limited feedback alongside the wired installation and the listing’s unresolved power and resolution details.
