Hi, I am looking at the Geovision GV-FE520 vs the Mobotix Hemispheric Q24 for a new system. Does anyone know which is better or are they similar? I could not find any comparisons. I know that the FE520 is a 5 mp whereas the Q24 is only 3mp. Also, I have heard that they both have the same view options (different types angles of view options) both being fisheye lenses. Is that true?
