Few things bring me more joy than finding inexpensive tech products that turn out to be extremely useful. That's the case here, with the LaView 4MP wireless security camera. As you can see it's shaped like a lightbulb, so it can screw into any standard socket, and it's a fully-functioning smart cam. Features include 2K video, 2-way audio, a built-in siren, motion tracking and detection, and right now it's on sale for just $20.
