The Verge reports that Wyze Labs has discontinued its first-generation WyzeCam, released in 2017, which I reviewed in “$20 WyzeCam Security Camera Is Almost Too Good to Be True” (28 February 2018). As of 1 February 2022, Wyze Labs will no longer sell or support the first-generation WyzeCam, and the company discourages its use due to a lack of security updates.
In an email to affected customers, Wyze Labs included a $3 coupon toward the purchase of a new WyzeCam, a decent discount. The current third-generation WyzeCam costs $35.98 but is also usable outdoors, unlike the original WyzeCam. These days, I usually recommend the $39.99 Eufy Security Solo camera, which is limited to indoor use but is HomeKit-compatible.
