Jittery
I upgraded to Yosemite and then their was an update to Isentry which I installed from that point on Isentry doesnt work correctly when you start the motion detection you can see the video and then it just gets all jittery and the program stops working shortly after that, I dont know if it is the Yosemite causing the problem or Isentry, hope they fis it soon.
