Now I just need to figure out why the camera will not focus. GRRRR!
welcome
I'm now in touch with Andy on the focus issue. The camera will not focus beyond two or three inches. Everything beyond that is blurred. I hope that Andy has an easy fix because I don't want to have to deal with getting this camera back to Asia.
No matter what adjustments I make, the best I can do is soften the glare at best. I can do this using Manual or Zoomprio settings. I guess the are I'm looking at most, is just too close. Distance is about 16 feet away. I may have to go with external IR in more of a flood type for a wider area. Or relocate this cam and use 2 5231's instead. I really like the daytime pic and moveability of this cam, especially for watching the bird feeders.

Have you tried clicking the "lens initialize" button? Can you manually focus beyond that using the + and - Keys?
Unfortunately, you may have gotten another lemon. I've got a bunch of bugs and issues with mine. Few reports of units not focusing in low light, but I'm assuming lightning conditions don't matter in your case.
If you have to send it back, it would be a big cost savings if you could take the unit apart and simply send back the small camera module inside without the heavy housing and pan/tilt motors. Whether they would work with you on that or expect the whole unit, I don't know...Please keep us posted on your results.

Yeah, you're not going to be able to do much more with that scene. The wires aren't helping matters, but the biggest issue as I see it is you're trying to illuminate a wall that's almost parallel to the camera view. In order to properly illuminate the farther-away portion of the wall, the closer part is going to be over-exposed. Properly expose for the part of the wall close to the light (which is being done in this example) and the distant parts of the wall are going to be under-exposed. Notice the spotlighting effect is much more pronounced on the top-left side of the image. You'll probably need some external lights in this case, preferably one closer to the cam and one in the distance to help even the lighting against that wall.
I didn't know about the lens initialize button. I appreciate the tip. Unfortunately, that didn't help. The camera simply won't focus until the zoom level is 3 or greater, even with use of the + and - keys. There simply isn't enough travel. I very much need the widest view, so the camera is of little use to me at present.
Andy responded to my email and asked for more information. I imagine that he is working on a solution. I'm willing to engage in surgery on the camera if Andy can provide clear instructions and without risk to my ability to return the camera. BTW, I ordered from Andy because of his great reputation on this forum although I could have purchased the same item for less from other sellers.

Hmm, I imagine you've tried restarting the unit...If so, that's a quick and simple option to test. Also you could try resetting to default. That's been known to clear up some bugs in the past, although I have my doubts that it would do any good for this problem. This sounds more like either the lens or the focus motor is defective or not installed correctly.
Hopefully you'll hear back soon from Andy. It's night in his part of the world now, but should be morning there soon.
As I mentioned to someone in another thread yesterday, these units have potential, but I feel they were rushed into the market prematurely without enough time given to test for bugs. Given the price compared to similar style units on the market, I also have to wonder about hardware quality. We're getting a lot of motors and parts for this price range. A good zoom lens itself can cost $100 or more. My first instinct when I saw "25x starlight PTZ for under $350" was "Too good to be true"..Some corners have had to be cut somewhere.

I assumed it's the camera matching the thread title and on page one.

That sounds like it should be a great cam. I just wanted to make sure it wasn't the one I ordered (5231 turret cam).

This is sending the video to my 5216 NVR as sub stream 1. It won't send as main stream. If I turn off sub stream 1 I get no video on NVR Anyone else having this issue?

I have Dahua SD49225T-HN for about two weeks now. Setup with my LaView LV-N9808C8E NVR was really easy using ONVIF protocol. Looks like basic control for PTZ works well, same thing with remote app, I can control basic staff like camera movement, zoom, presets easily with my NVR interface or LaView android app. Camera is set to Motion Detection recording, and everything works well, but 3 days ago stops recording motion. Still can record camera on my NVR by forcing to record or switching to continuous recording, but this is not what I want. Loading default settings for camera doesn't help. Other cameras (LaView brand) also set to motion detection recording works with no problem. Any ideas? TIA.

I was just reading the API document and found that this camera allows control over its absolute position, which means you can craft a URL to select horizontal degrees between 0 and 360, vertical between 0 and 90 and zoom multiplier.
For example:
http://IP/cgi-bin/ptz.cgi?action=start&channel=0&code=PositionABS&arg1=180&arg2=45&arg3=0
arg1=pan
arg2=tilt
arg3=zoom
For example:
http://IP/cgi-bin/ptz.cgi?action=start&channel=0&code=PositionABS&arg1=180&arg2=45&arg3=0
arg1=pan
arg2=tilt
arg3=zoom
Attachments
can be done with presets to

Of course, but this allows you to go to any location without setting a preset. Not sure what use it would have yet.

there is also a number value assigned to zoom level.

Jet, looks great! Any issues when the wind picks up since this unit does not have image stabilization? Did you install the pole and if so, how deep is its foundation? Looking to do something similar and want to make sure the pole is not under engineered. By the way I would blurr out the address if I was you, but if you see a runner checking out your setup, I come in peace
