That must be one tall pergola lol.
PTZs work best higher up and according to this review once the lens gets close to level it struggles with focus due to the dome.

That must be one tall pergola lol.
PTZs work best higher up and according to this review once the lens gets close to level it struggles with focus due to the dome.
Pergola is 11 feet, but there is a significant downslope another 10-20 feet. I won't be purchasing until I am confident the focus issue is resolved.
It doesn't make much noise as it is tracking, until it stops tracking then returns home. You might hear that short burst of noise up to 50' away.
Indoors, sure you could use it without the dome without issue.
Any that fits from your local hardware store.
I would not leave the connections exposed.

On my monitors, the night videos don't appear too dark.
Yes, night has been tweaked settings wise.
Edited to add: There is plenty of room left to increase brightness and contrast settings in my case.

Thanks @looney2ns , this camera is on my list. You put in a lot of time to make the camera a lot better. I certainly appreciate it.
Anyone know where an actual spec sheet is available?
With that awesome auto tracking capability, no more pissing and moaning from me. It's back on my list of must have cameras. Along with the Color4k-T180.
It doesn't look like BLC is being used in the Backlight setting for the night shots. If not, what is being used please?

Most of us try not to use any backlight during night time. It gives a great static image but usually results in artifacts or blur during motion.
Post #1 and the listing pretty much gives the specs:
Andy posted somewhere the tentative spec sheet, but I don't know if it differs from what is actually selling now.
The specs are there, but other than just 'screwing on to a soffit', are there any other mounting options. It's too new to even be on the Dahua International site, so no spec sheet there. The beauty of official Dahua spec sheets, is they normally show the most common mounting options, and that's what I'm looking for.
Yes Wrong link. I have the correct PDF, but can't seem to include it here. Can't remember where I got it from.
See post #33 below. It worked finally.

Thanks for the review. That focus issue is surprising to me. I've used a few PTZ bubble domes like that and not seen it nearly so bad before.
It is an interesting cam for sure. But I wonder why they chose the small 4MP sensor. Probably gets a tighter field of view as a result. But I would gladly take a better sensor.

I don't see how. The radius from the center to the back of the mount is only 2 1/2". The cam diameter is 6.7", so the radius is more than 3".

Thanks for the review Looney.
Personally, I have a couple of issues with this cam for my needs. One is the dome, I'm not a fan of domes and can't help but think it's been made to designed and built to look high tech and trendy rather than with functionality in mind - turrets all day for me.
Second issue I picked up on is th shallow depth of field despite a small sensor. The guy walking the collie was out of focus whilst the the collie was razor sharp. You could blame dome curvature and maybe it still is, but with them so close together, I can't help but feel the're in the same area of the dome and thus it's shallow DOF with the camera focus locked to the dog.
Thirdly, I'm not keen on the use of such a small sensor. For many people's applications this won't matter as many people and businesses are quite happy for B&W and IR. However, having seen full colour at night, for me it's large sensors and full colour all the way.
With a couple of adjustments, it will probably be a good cheap for PTZ for many. From a purely personal pov, it just wouldn't be one for me or those who like colour at night.

Price is a little higher than I wanted to see too. For $5 more you can get the tried and true 2MP 25X. The smaller size appeals to me a lot but not sure the size trumps price/performance enough.
Thank You! @samplenhold . New problem now as it shows the PFA101 mounting adapter as not having a 124mm bolt circle that the Spec sheet says is required. Seems like the pre=production spec sheet may be incorrect which would not be uncommon for Dahua. Am I missing something? This is getting to be more complicated than it should be.
@EMPIRETECANDY - Can you post an updated spec sheet for this camera? Or, maybe provide what mounts WILL work with this camera?
Looks like a lot of potential for this camera. I’ll buy when more of the bugs are fixed.
