Walmart is clearing out the Motorola Orbit wifi camera for $35. YMMV
- 1080p video
- battery allows it to be on standby for up to 3 months, or a total of roughly 7 hours of video, so definitely not suitable for routine surveillance (unless you plug it in), but has its uses
- 150 degree view
- water resistant
- microSD card slot with included 8GB card
Cloud recording requires a monthly subscription; viewing and local (microSD) recording does not.
It's got mixed reviews, but I suspect that the negative reviews are because 1) not strong enough wifi network signal - the bane of many wireless cameras/doorbell cameras, and 2) expecting to view an active/routine surveillance site for hours a day without plugging it in.
