Thank you soundy, I understand now
@tomcctv, Yes I think I will leave my PC (or Mac ^^) in the stable and the idea was just do watch if somethings happen during the night. And it will be great if I can see over the internet but I can use a VNC, it's not a problem. (I have Wifi in my stable).
For me the most important thing is recording and save it. So if somethings happen during the night, I can watch it the morning.
