Trendnet's TWC-L10 Indoor HD Wi-Fi Light Bulb Surveillance Camera is worth your money if you want a two-in-one smart device to illuminate and monitor what's happening in a room from above.

The TWC-L10 combines a recessed 40W replacement LED with a 720p HD live streaming camera. It can detect motion, save recorded video clips locally to a microSD card (cards can be up to 64GB, but are not included) and has an integrated microphone along with a speaker for two-way audio. Trendnet's TWC-L10 costs $100 and is currently only available in the US. 

The camera's wide-angle 185-degree lens has digital pan and zoom capabilities so you can see a whole room with relative ease, but details like a credit card number or a phone's access code would be too blurry to make out.
