Camera view cuts through objects

So I have this problem. From time to time I think I am pressing something by a mistake and this happens:


The view from camera cuts through my objects.

What is it, what is it for and how to turn it off? Sorry for a thread only for that, but I dont know how to google for it, as I don’t know how to call it.

Go to the ‘N’ panel in your 3D view, and on the ‘view’ panel try to make your range limits smaller. If that don’t work play around with them.

Looks like Clipping Border.
Default hotkey: ALT+B
