With respect to your last question, the answer is yes.
Thanks JackBauer for the question and aster1x for the answer. I've been curious too. I'm wanting to replace 1.3MP Foscams (4mm lens) with 4MP Hikvision or Dahua. If I went with a 2.8mm lens at 4mp I should have as good, maybe better clarity as the 1.3MP with 4mm? The middle of my street is about 50 feet from the camera, the sidewalk about 33 feet. I'm not really expecting license plate recognition but face recognition would be nice. I'm assuming the field of view is close to the same on different cameras with lens of same size?
