Amazon offers its Amazon Cloud Cam Indoor Security Camera for $99.99 with free shipping. (Best Buy via eBay, Bed Bath & Beyond, and Home Depot charge the same.) That's the lowest price we could find by $14, although we saw it for $10 less two weeks ago.

It works with Amazon Alexa so you can view live feeds on any compatible Amazon device, like the Echo Show or Fire TV. Features include a 1080p video resolution, 120° field of view, night vision, motion detection, and 2-way audio. 24 hours of cloud storage is included for free for up to three cameras; additional storage can be purchased, with plans starting at $6.99/month.
