Amazon has the new hard-to-get Wyze v3 1080P Indoor / Outdoor Wireless Smart Home Camera for $29.98 with Free Shipping for a limited time. Wyze has this direct for $23.99 but they charge shipping (about $5.99 for one camera) and it has been on backorder since launch last year.
The v3 updated Wyze cam adds IP65 water-resistant rating for use indoors and outdoors, color night vision, and a built-in siren. It still offers 1080P video recording with motion & sound detection, free cloud storage for recorded clips, loud two-way audio, and integrates with IFTTT, Amazon Alexa, and Google Assistant.
