Data from Amazon and official Reolink and TP-Link sites.

2026 verdict

Color night vision and solar charging put the Reolink Altas PT Ultra ahead of Tapo's indoor fixed cam.

Winner

Reolink Altas PT Ultra

$188.99

Buy on Amazon USA

It wins this security camera matchup on weather resistance, solar charging, dual-band connectivity, 2K, 4K, color night vision and a wider alert set, so a yard gets 4K tracking instead of a 1080p shelf view. The TP-Link Tapo C100 remains the more affordable indoor option, with a better owner rating, native RTSP and a privacy zone the Altas does not list. Go with the Reolink Altas PT Ultra for solar 4K outdoors; go with the TP-Link Tapo C100 when a tiny indoor camera with RTSP and a privacy zone is the job.
