So I got my hik with alarm in/out and audio in/out. Has anyone else done anything fun hooking extra things to their cams like PIR sensors, arduinos, raspberri pis? I wanna play with this one a little before I put it in to service. 
So far I have access to one PIR sensor I just have to get it off the wall.
