Before I go any further, this isn't for me (I will be eventually getting some Dahua camera's) but for my parents (They are building a house, and wanted to get some cameras installed...basic stuff nothing fancy). They looked into a "Security Installer" but it was ridiculously expensive. I have some networking knowledge enough to at least get some basic camera's going with an NVR. Regardless they want to have a Warranty to be able to send it back. (Not that I don't trust Andy as an seller, but they are pretty adamant on wanting a Warranty-able one). This will still be useful for me though because i'll probably order the same (International ones) from Andy when I get mine (Since they want the same setup). Basically they have a House with 2 entrances, both are covered with a porch-type roof. The Cameras will sit underneath. The front one will need to identify mostly someone at the front door. From my understanding, 4MP isn't really worth it over 2MP? What if something like a Floodlight is on? I'd ideally like to get at least 1080p. Also from my understanding the Varifocals are better and worth the slight price increase (Pretend im on a strict budget: If you HAD to recommend a fixed focal length, what would you recommend?, since based off US resellers the Varifocal's are much more expensive) Is this statement basically true when it comes to Focal Length: The Higher the focal length, the smaller the FOV but better the details in that (better resolution) I've checked out the cliffnotes, and basically i've heard that turrets are better than Domes or Bullets. I like the look of Domes and Bullets better...are they that bad? (I know they attract spiders, but it's not a huge deal for me to clean cobwebs every so often). Anyways what i've looked around on U.S. retailers (B&H seems popular here, are they ok? besides the price premium?) and these are the ones that seemed decent for the price (These are all fixed ones, since the varifocals were a little outside price range: N44BB33 or N44CB33 (Bullet, whats the difference? my switch provides 802.11af, does ePoE help at all?) N44BG53 (Turret) N44BL53 or N44CL53 (Dome, again I can't find a difference) then there are the N24BL53 (Dome) N24BB33 (Bullet) and N24CB33 (Bullet) which are more expensive by about 50 bucks. Im guessing because they are 2MP? All the naming schemes get confusing ha. Are any of these decent? Pretend I have to get U.S. only cameras at least for my parents, so im trying to stick to the U.S. model #'s.
