I've never heard of these but for the price looks good:
Amazon.com : Portable Mini IP Camera, UOKOO 1280x720p Home Surveillance Camera Wireless IP Camera With Built In Microphone WiFi Security Camera, Motion Detection Black : Camera & Photo
and
http://www.amazon.com/Portable-1280x720p-Surveillance-Microphone-Detection/dp/B017SUD1K0/
I know lots of people here want security cameras so this might be worthwhile.
