I’ve been messing about with indoor security cameras and found the VStarcam to be pretty good. Works in any browser (doesn’t have to be IE like some others) and has a great Android phone app. Easy to set up too. I tried to get it working with Zoneminder, but for some reason I couldn’t get the path right. It does have an SD card so can be used as a stand alone unit with motion recording. Video quality is excellent, and the two way audio is hilarious. I’ve put one into a retail environment and doing another next week. For the money, they are a bargain. You can score one here
