Use a PFA120. Use a PFA140 if you want a power box.

thanks! is the powerbox only if you are NOT doing POE?

No one is whining about anything except for a few of you that don't think I deserve the right to my own opinion. Specs are there for a reason. They weren't invented just for me. They're there because most people want to know what they're buying. If you don't care if a product has accurate specs, then fine, buy the product and be happy with it. Doesn't mean everyone else feels that way and the many that do care about specs deserve to know if they're accurate or not.

There's plenty of "security cameras" that I've been perfectly satisfied with. They do exactly as they're advertised. Only time I'm not satisfied is when it doesn't do what it says it will do. If you can't handle a negative review, then by all means, click the ignore. My reviews are for those concerned about specs, not for those who want a mystery camera to show up at their door.

You brought the issue to everyone's attention, and hopefully the specs on the website get corrected, or at least anyone researching the camera who is looking for long shutter times runs into this thread. Thank you for that. I think everyone here appreciates finding out about inaccuracies in the specs.

What's off-putting is the crusade and constant false advertising accusations. If you look across Dahua's website, almost all the starlight models list the slowest shutter speed as 1/3 (including the 12x zoom sibling of this camera). Even the Ultra bullet's slowest shutter is 1/3. The only exceptions I saw are some of the PTZs. Either there's a copy/paste firmware bug, or there's a copy/paste website bug, but it's pretty obvious this isn't a false advertising practice of Dahua's.

And if messing up a spec sheet is enough to boycott a brand, you're going to need to boycott pretty much everyone, because I see spec errors in every tech sector from garage startups to fortune 100 companies. I wish specs didn't have to be verified, but they do. It's an unfortunate state of the universe, people make mistakes.

The PFA140 is for use with an external power supply, ie: not using poe/poe+. It will give you a weather proof enclosure for power as well as the ethernet cabling. I would not go with external power on any of these cams unless it was really necessary. POE is the way to go. For most, a PFA120 is all that is needed.

Exactly what incorrect specs are there? Are you talking just shutter speed? What all is not matching up to the specs sheet on this camera?

 

[fenderman]

I mostly deal with more complex commercial situations where exact specs are needed

Except that is not true, at least when it comes to surveillance cameras. You are a photographer using surveillance cameras to look at flowers and grass....You dont install cameras commercially. There is good reason to bash shit brands like Huisun..they produce unreliable junk cameras and sell them as surveillance cameras..glad they work to properly capture the skyline and grass for you, but the rest of us could give a rats ass if the shade of green or blue is not to perfection....what does matter to us is a shitload of huisun cameras dropping like flies.

Uh oh, I see him typing another novel explaining he has rights!

Does anyone happen to know if this Parapet Mounting Bracket will work with the sd49225t-hn?

Yes, this works. You need to learn how to use the Dahua International site for all this info. This is the link to the Spec sheet for this camera.

So the Adorama alibi brand should be compatible with the Dahua brand PFB303S ? along with the PFA111

I cant find any pipe diameter and thread size information anyplace.

Don't know anything about the Alibi brand. It's not Dahua so I would assume it would not be compatible. If you need just about any of the Dahua mounting solutions, a good USA source is B&H.
They are an authorized Dahua seller, usually free shipping, and they stock alot of the mounts. If not, they can usually get any of the special order stuff in a week or so.

I would ask the seller, they sell the Dahua adapter you need, so give them a call and ask them if it will screw in.

I have the mount and from my understanding it doesn't get ordered that often. I have a SD59230U_HNI on it fixed to a 4" pole using some U bolts and using the standard PFA110 that came with the camera.

Looks great painted. First one I've seen that doesn't look like an eye sore.

Would this POE switch be sufficient
Linksys LGS108P 8-Port Business Desktop Gigabit PoE+ Switch

 

[wxman]

Linksys LGS108P 8-Port Business Desktop Gigabit PoE+ Switch

Yeah, that would be plenty sufficient for running this cam. I believe the max power this cam uses is only like 19 watts, so any PoE+ should do the job

Thanks for addressing the situation in an adult manner. Even though it's a critique, you explained your feelings respectfully and I can appreciate and understand where you're coming from. I wish others would have done that rather than flooding me with rude insults...but such is life on an internet message board. It really wasn't my intent to "beat a dead horse", so I do apologize if it came across that way. Part of the repetitiveness was because based on some of the replies, I felt some people were trying to help but misunderstanding the problem. Other parts of it were just blowing off steam. Perhaps inaccurate specs are more common than I realize and I've just been fortunate that this is my first experience getting burned. I'm hopeful that they'll correct the specs on the website and even more hopeful that future firmware updates will correct some things. None of the issues I've had are enough to make me want to sell the unit and I really think it's a decent cam that has a lot of potential.

Exactly what incorrect specs are there? Are you talking just shutter speed? What all is not matching up to the specs sheet on this camera?

I haven't even tested a lot of things yet..but as of right now, the parts not matching the specs:

•Shutter speed limits
•White Balance options
•Tilt range (fortunately, it's more tilt range than the specs describe, but could have just as easily been less)

There's also a few bugs that are hopefully firmware related and will be fixed, including incorrect FTP upload timing, ptz presets drifting, white balance bug (even in "auto" mode) that randomly changes everything blue when the white balance hits a certain value and a number of other, mostly minor things that have been mentioned by other posters.

Except that is not true, at least when it comes to surveillance cameras. You are a photographer using surveillance cameras to look at flowers and grass....You dont install cameras commercially. There is good reason to bash shit brands like Huisun..they produce unreliable junk cameras and sell them as surveillance cameras..glad they work to properly capture the skyline and grass for you, but the rest of us could give a rats ass if the shade of green or blue is not to perfection....what does matter to us is a shitload of huisun cameras dropping like flies.

Definitely not a photographer! I don't even own a DSLR cam! lol. I use a bridge cam to take nature shots as a hobby, but that's only a couple times a year...My business does provide IP cameras to commercial entities for security as well as IP cameras for weather and traffic (Even had government and news media clients). There's also millions of IP cameras used as weathercams by hobbyists on Weatherunderground.com worldwide. I don't think people realize just how much these are used for weather monitoring, but it's a booming industry. Also, just recently had a client that I helped set up a commercial network of weathercams at airports (using Hikvision IP Cameras and they work perfectly for the job)...We're not looking for DSLR quality or the exact shade, but something reasonably close. When a cam makes the sky looks purple, white clouds look red and green grass look dark brown, it makes it hard to use or recommend them for that specific purpose.

For those using it as a general security camera, it's great! Even gave it a 4 out of 5 rating on my review under "use as a security cam"; pretty high rating. Much higher than I rated Huisun because of their failure rates and hardware limitations. There's only 2 situations where I have concerns recommending it; As a weather cam (at least until a firmware fix can correct white balance issues) and on highly specific security projects where exact specs will be critical (because there's errors already noticed in the listed specs and possibly more that I've yet to discover)...

Even setting WB specifically it gets funky on its own? Presets drifting is not good to hear. Huh.

I've not noticed the problem in Manual WB setting (of course you have to keep changing the values as the day changes, but that's with any unit on manual WB due to different light frequencies as the sun angle changes)...The funky blue shade happens mostly in "sodium lamp" mode at random times, although it's happened a few times even in auto mode..It's like the blue channel gets cranked all the way up and gets stuck. Once it does this, it doesn't go away (even in auto mode) until you change WB settings to something else and then switch back to where you were....

The preset drift was reported by another poster on here that's had the unit a lot longer than I have. I've not seen any noticeable drift in my presets, but mine's only been up for like 3 weeks, so not really enough time to tell. There is a firmware update that this poster was going to try in hopes that it fixes his preset issue, but he hasn't done so yet.

Do you have the Dahua PFB303S mount or the Adorama alibi brand?

I have the mount and from my understanding it doesn't get ordered that often. I have a SD59230U_HNI on it fixed to a 4" pole using some U bolts and using the standard PFA110 that came with the camera.

 

[dalepa]

SD49225T-HN ordered from @EMPIRETECANDY !

Please forgive all the newb questions heading this way...

For starters, do these dome cameras auto level somehow, or it level mounting critical for 360deg operations?


I can't seem to find the PFB303S mounting pole in the US. Any tips on places to buy?
