I've found the Mobius B action cam useful and affordable for general sousveillance. It's a primitive interface, but can be configured via a text file across any platform. I presently have mine configured as a motion cam, which is sensitive enough to effectively use as a standard camera too. Vids and pics can be viewed through mini usb on a phone or pc. The B has a wide angle lens and the text file has an option for narrow view. I often use it as a rear facing dashcam when someone gets too aggressive, eg tailgating, etc. For home I use a webcam and the Motion program, which works quite well for me. Lots of options in the Motion config file.
