Hello, I am seeking some advice on how to adjust these two cameras. I believe you need to turn the two screws to be able to adjust them but would like some more specific advice on what each screw actually does. on the lens it seems to say 2mp, but these are analog cameras. supposed to be 2.8 - 12mm varifocal lenses. they are also supposed to be the exact same cameras, but as you see below there seems to be some sort of inline remote that was only included with one of the cameras. the remote does not seem to do anything as I have plugged in the camera and tried it out. also, I have a couple of other bullet cameras (not in front of me atm - will update later with pics) that are supposed to be vari focal as well (2.8 - 12mm), but upon closer inspection once they were purchased they clearly say 4mm on the front of the lens leading me to believe they are not vari focal any comments would be greatly appreciated.

Camera 2

supposed to be an 8ch full D1 dvr with 8 audio as well. thanks for the help.

I see no reason to upgrade unless there are new, useful features that can be made available. it is NTSC. The dealer swears its a dahua but I got a shady feeling from him - which is why I came here to verify. thanks tom - what would you say is a fair price for this unit? (am I allowed to ask that?) I paid 400 CAD.. he tried to charge me 450 saying that his associate told me the "dealer price" by accident, so my BS meter was going off from the start..

Are there any benefits to upgrading the firmware on this unit (assuming its the dahua?)

luckyfella:thanks, I was in the middle of posting pics, your quick!
