Whichone is better between mobotix and axis camera?

I don't know anything about Mobotix cameras, but I've used low-end Axis cameras - the 205 and 206. Over a period of 3 years, I've found them to be very reliable. The picture quality and general performance fully meets the printed specifications, which is a rare thing in a low end camera. If you're a programmer, they also have a nice HTTP-based API.

The pictures in the right-hand column at

were taken with a hacked-about Axis 205 that has been sitting in an unheated spider-infested box for 3 years, and it's still taking good pictures.
