    While panning/tilting would behave somewhat strange, presets would work just fine. With my own PTZ models, I've found that I use those more than manual panning & tilting. They're also handy when you can trigger them based on an external event... ie: a door was opened, so flip over & zoom to the door for 30 seconds.

    But many folks find that having 2 cameras is often better & most cost-effective than a single PTZ. *shrug*

    ** ok, nevermind.. SkyLake is totally right. You could maybe adjust the roll so that some of the angles would look fine, but the rest would likely be upside down.

    Hi Q,

    This is how it would look like, when you mount a PTZ camera vertically on a wall. As you can see, it would only be useful as a static / fixed camera after mounting it like this. Otherwise you would go seasick in a very short time :D

    Other than not having to make a huge hole, what's the advantage of this cam over the SD52C225U-HNI which has higher zoom, starlight, intelligent features, and is also $320 from Andy...?

    There are instances that the SD52C225U-HNI could not be recessed into a hole, so this could be used instead.
    All these cams are designed with business's in mind, not home owners.

    This one install on the ceiling directly, like turret cameras. No need dig hole.

    @looney2ns In your videos, is the camera autofocusing after ptz'ing to each new location? Meaning, at any point in your videos did you force a manual focus?

    Another great review. I caught myself scrolling up to the top to check and make sure this was a 12x. I like this one. I'm starting to see what you guys are always talking about with domes outside and how it takes away from the picture quality. I'm thinking this would be a great one for inside the bars I'm in for the owners to have a very clear picture of the bar areas.

    So the Dahua 2MP 25x Starlight IR PTZ Network Camera (SD49225T-HN) is $320
    and the
    Dahua 2MP 25x Starlight IR PTZ Network Camera (SD49225T-HN) is $340 with no dome and 25x

    Is there any reason not to get the 25x over the 12 x for outiside. I liked them both but the 25x seems to win out in my opinon better value as well.

    A powerful optical Zoom is always the better choice.

    Size and weight differences are worth considering. I have a SD59230U-HNI that has been sitting in the box for over a year because I haven't figured out a good way to mount it on the corner of a metal building due to the weight, and even at 14ft mounting height it looks huge!

    I have the Dahua corner bracket, unfortunately the legs aren't long enough to clear the protruding outside corner trim so I can bolt through the PBR panels into some sort of backing.

    Could you build the legs out with treated lumber mounted to the PBR panels, then attach the bracket to the lumber.

    So this allows external microphone input, why the bare wire over RCA? That zoom is impressive
