At present I'm using EvoCam which is really cool, sets up so easily on a MacBook and uploads photos to my website every 30 seconds or so but my problem with EvoCam is that it eats up 76% of my CPU usage and the MacBook fan runs continuously when it is on. That's good, of course, but it is annoying. If Periscope works as well as EvoCam and uses less CPU then I'll switch.

Can someone using Periscope check their Activity Monitor (In your Utilities Folder) and see what percentage of CPU activity it is using and report that here?

Thanks
