Dahua 2MP 25x Starlight IR PTZ Network Camera (SD49225T-HN)

How reliable is the PTZ function? I'm aware that certain rules need to be established via the IVS function. I feel PTZ eliminates the need for multiple placement of cameras. If suppose the subject was out of frame (i.e. on the side of the camera), would this PTZ be able to auto-orient itself towards that direction? Are there any proximity sensors built in to detect activity?

Nope. But of course you could set up something like this yourself. You could use motion and other sensors which are connect to smart home and trigger an API call to the cam, which then goes to a specified preset. Or in combination with other cams with wider angle of view and a NVR. In the NVR you can configure IVS events for these cams and in the case of an event the PTZ is going to you configured preset.
You could also get a PTZ with autotracking function. But the cam has to see the object first before it could track it. And I can’t tell you how reliable the autotracking function is. Some users didn’t seem to be very happy with it. At least for the SD59225. Maybe the ultra series do a better job with this.
The SD49225 had the best value for price for me. For twice since now…

I've had this camera a week and love it so far. One question- is there a way to set up a tour that runs once and then stops?

I'd like to set up home automation events that trigger tours, but I don't want to risk starting a tour, having the "stop" command fail, and then accidentally recording hours of meaningless PTZ movements.

I tried setting the duration of the last preset in the tour to 0 or -1, but lowest duration the ConfigTool will accept is 5 seconds.

I also tried using the HTTP API with code=StartTour and arg3=2 ("automatically"), but the tour still runs until stopped.

Thanks.
 
Thanks for pointing out the autotracking feature as well as integration with SmartThings. It'd be nice if a future model encompasses / integrates proximity sensors (powerful enough to detect moving objects / subjects from certain distances -- hopefully I'm not dreaming --- this could certainly be a reality someday, lol)

Not to be too broad, but do you think everyone should install at least one PTZ as an overview camera or have one PTZ camera to replace two standard cameras? :) I'm not sure if it would fit the bill. I have a couple of cameras installed in which I feel a PTZ alone would have served better. However, the Bosch Motion Sensors I use don't work well with the SmartThings Hub; I can't adjust the refresh interval.

You would install a PIR sensor, and when it is triggered, have a preset to move to that location.

Thanks, as long as the PTZ can react fast and if the PIR motion sensors are installed in a concealed manner, this method should work. Are the Bosch Motion Sensors compatible with this PTZ?

Also, motion sensors are usually triggered when it detects a certain heat signature. What about in the case of falling or moving objects. Can these PIR's detect that too?

Most likely because your approach sucks as you already know. You were basically calling Dahua junk because it doesn't fit your bird watching or whatever it is you do. The cameras are a pretty good bargain for needs of a security camera, which is what this site is pretty much for.

Only reason it became a big deal was a few folks like you with shitty attitudes because someone made a complaint about your "holier than thou" Dahua brand....Stick with the facts, my complaint had nothing to do with "bird watching" and I did not say Dahua was "junk"...I was looking for a cam that could handle full surveillance which the specs listed on the camera supported...What I received did not live up to those specs and I voiced my complaint so others looking for those exact specs would know not to expect them. I also made it clear that it was a good camera for basic security and that it would fit most people's needs...What I said was truthful and there was no harm in it whatsoever. Had it been any other brand, there would have been no issue. Just 3 or 4 posters here that have almost some type of cultic obsession with Dahua that took issue.

Now we're finding more and more issues coming up with time on this particular unit...It's no longer just shutter speeds, white balance and FTP issues....Now it's more serious problems. We find out there's focus issues in certain scenes. They're not IP66 compliant as 2 have leaked in blowing rain (including mine which caused the POE to blow out)...Despite providing evidence of the problem, Dahua will not send a replacement circuit board until I spend over $15 to send the old circuit board back, wait a month for it to be delivered to them, then wait another month for the replacement board to arrive. I'd likely be looking at 2 months out of service waiting to get a replacement. Now they've released new firmware with problems and it blocks you from being able to downgrade back to the old firmware to get rid of these problems.

This is not acceptable and people need to be aware of it, even if it hurts your feelings.

All you did was bitch and moan instead of just returning it and finding something that fits your needs. You are one of the cancers of this forum.

Have you priced shipping a unit of this size and weight back to China? You're probably looking at a good $80 to $100...Maybe that's pocket change to you, but it's not to me. I had reason to "bitch and moan" and to warn others of the troubles I had faced (and still face)....They've done nothing after all these months to correct the problems, not corrected the specs on their website and only released firmware that's caused more problems.

It's nothing personal against Dahua. I've praised Dahua where deserved while pointing out faults where they exist. As I have done with every other brand...And when someone has a problem (regardless of the brand), I try to help them solve it to the best of my ability rather than tell them "your problem is irrelevant to me, quit bitching". That supposedly is the purpose of this forum; Honest consumer reviews and troubleshooting help for those with problems....Only way I'm a "cancer of the forum" is if the real purpose of the forum is to be a biased marketplace for selling Dahua, which you seem to want...

I’m not replacing anything with my PTZ. They are in addition to my other cams. With the PTZ I’m able to manually watch detailed at things that I want to at a particular moment. And for having close ups of scenes where IVS events got triggered.

Well, thanks to the positive reviews here, I placed an order with Andy for four of these cameras (one for me, the remaining for friends/family). I installed mine yesterday and have been playing with it non-stop.

Here's is the stock information page - I have updated nothing so far:

upload_2017-10-21_8-20-2.png

So far I have found nothing that provides even the slightest amount of buyer's remorse. I do, however, have a couple questions that I'm hoping the experts here can help me resolve:

  1. On the video overlay section, the "north" compass needle seems to spin in the opposite direction as it should when I pan the camera. That is, the head of the arrow is facing 180° away from the correct orientation as I rotate. It is correct when I'm pointing due north or due south, but it is pointing south when the camera is facing east of west. I have 'calibrated' the software by pressing the "north" button when it faces north.
  2. When using Blue Iris (console or app), is it possible to control the IR night/day mode? I've tried with the defaulted ONVIF and Dahua profiles under PTZ, but neither provides IR control. All other controls (brightness/contrast, etc) appear to work. It would be nice to switch off the IR/night mode when enough ambient light is present but the camera thinks it's too dark.
This camera is being used in a very remote area that has no light pollution at night. That means staring up at the stars is breathtaking (even for someone like me who is not into astronomy). None of my other cameras ever saw any stars - but with this one, I can see every little point of light. Initially I thought I had a bad imager with burned out pixels - and then I realized those are actual stars/constellations!

I got mine up yesterday. I live close to the city with a lot of light pollution and still saw plenty of stars. The zoom on this thing is amazing.

This must be a new feature. I haven't found any compass on the November 2016 firmware; only a digital printout of the pan and tilt location in degrees.
 
Another I want to get addressed is how someone mentioned the delay when switching directions and responding to motion via PIR. Has this been resolved in the latest firmware? Or is varying from individual to individual because of how they programmed the IVS? Somehow, I'm still thinking about PTZ as a future addition.
I’m not replacing anything with my PTZ. They are in addition to my other cams. With the PTZ I’m able to manually watch detailed at things that I want to at a particular moment. And for having close ups of scenes where IVS events got triggered.
 
I got this PTZ to give as a Christmas present. I thought I should test it first.

When you first came around, there was no "praising"... it was a bunch of whining about what? Shutter speed was it? As for shipping to China... I guess that's the risk you take not buying from an American vendor. Everyone wants to go the cheapest route, and then it doesn't work out for them, and the product/seller is the worst thing in the world(I know whenever I buy something from Andy, especially my 30x, all of the potential issues that could arrive were asked/told up front so there is no surprises). I have no, "feelings" in this, there are constructive posts where people identify issues/solutions/information... and then there was you, spewing a bunch of garbage... it sounds like you have gotten better, but can't seem to let go of the snide remarks here and there. I just happened to skim through it, when in all honestly I should just put you on ignore since I'm sure there is nothing I could benefit from you.

I would be the wrong person to ask. I haven't messed with them as of yet.


Motion PIR/Microwave

There are other options besides purely PIR sensor as the link shows. As for the moving objects, the auto track feature is okay at best. I get quite a few false positives which is annoying since I can hear the ptz move while I'm in the living room or bedroom. I didn't really buy it relying that it would work. If anything, if it worked, cool...if it didn't, oh well because the zoom on this sucker still blows my mind.


Thanks, as long as the PTZ can react fast and if the PIR motion sensors are installed in a concealed manner, this method should work. Are the Bosch Motion Sensors compatible with this PTZ?

Also, motion sensors are usually triggered when it detects a certain heat signature. What about in the case of falling or moving objects. Can these PIR's detect that too?

When you first came around, there was no "praising"... it was a bunch of whining about what? Shutter speed was it?

There was a number of things I praised on this unit...Even giving it a rating of "4 out of 5" for basic security. Shutter speed was one of the complaints, but there was also white balance issues, FTP issues and focus issues (particularly in low light)...

The part that flares my temper the most is not so much that these problems exist, but how they were dealt with when I reported them (by both the seller/company and some posters here). I was very upfront before purchasing the camera with the specific requirements that my project needed (in terms of shutter speed, etc.) and was assured that this camera met my specifications...What was delivered to me did not work the way I was told. When I reported that it was not working correctly, I was virtually ignored...Not so much as even an apology! Much less any offer to improve customer satisfaction....

First step in good customer relations is to acknowledge a problem/mistake, apologize for the inconvenience and either offer to fix the problem if it can be fixed or offer an alternative solution to make the customer happy if it's not possible to fix.....

For example:

"We're sorry for this problem. Looks like a firmware error has caused this. We will forward this to the technical department so it will be corrected with the next firmware release."

or

"It appears the specs were regretfully entered incorrectly by mistake and the hardware will not support this. We're very sorry for this. We take pride in properly advertising our products and will take measures to assure this does not happen again. You can return the product for a full refund or we will offer a small discount should you decide to keep the product as is."

This is the way a reputable company/seller handles business when they make a mistake. You don't just ignore the customer's complaints hoping they'll forget and go away. There was no sign of any remorse, no sign that they cared about my problem and no sign that these kinds of mistakes would not happen again...The fact that this was reported in February and it's now October and they've not so much as even taken 5 seconds to correct the specs on the ad speaks volumes about their lack of concern toward keeping the descriptions accurate. How is this supposed to make me trust the specs on future models and recommend it to others that may be looking for specific specifications? It doesn't...Therefore, my opinion remains; Camera's are great for someone looking for a general security cam, but if your project requires exact specs, you can't trust them...

As for shipping to China... I guess that's the risk you take not buying from an American vendor. Everyone wants to go the cheapest route, and then it doesn't work out for them, and the product/seller is the worst thing in the world(I know whenever I buy something from Andy, especially my 30x, all of the potential issues that could arrive were asked/told up front so there is no surprises).

I fully realize the risk involved with overseas buying, but a company needs to consider the specific problem at hand...If the unit was completely dead, no clue what was wrong, then yeah I can see shipping back all the parts for inspection and replacing...But in my particular case, we know exactly what the problem is and where it's located. It's a burnt POE port on a circuit board. The POE does not work, the POE port is black and it smells burnt...All else is working...The cause and solution is obvious. It's silly to waste $15 to send all the insides back just so they can say "yeah, this port is burnt, need a new circuit board"...I'm willing to do the labor and circuit boards cost virtually nothing in China, as is their shipping to U.S....It would not hurt Dahua at all to mail a cheap circuit board to me and be done with it. No need to waste my money sending all the insides back to them just so they can send them back with a new circuit board.

It's a waste of both time and money, plus it means my unit will be out of service for probably 2 months....I can run it with a 12v power cable until a new board arrives, quickly install the new board and have it working via POE again...No down time....To mail the insides to china (takes a month) then let them send parts back (another month) means 2 months without a camera. So much trouble could be saved with just a little common sense. Now I've had to purchase a whole new PTZ to replace this one since I will be months without it....Think that new PTZ is a Dahua? Not a chance! Why? Not because I've had problems with their unit, but because of their style of customer support that shows no concern for the customer's inconveniences.


I just happened to skim through it, when in all honestly I should just put you on ignore since I'm sure there is nothing I could benefit from you.

This is the difference between you and I...and really sums up the whole reason why we've not gotten along. You are here for your own benefit and don't care about others, while I'm here for the benefit of both sides. My motto is "If someone can't help me, then maybe I can help them"...If you had a problem, I would gladly do anything I could to help. Maybe I wouldn't be able to, but I would sure try. Sounds like your motto is "If someone can't help me, screw them, they have no purpose in my life"...Feeling that way is nothing to brag about, but whatever makes you happy.

It's time to forget it and move on. We're never going to agree and there's no point in continuing to argue over it. Sometimes you just have to agree to disagree and let it go...Take it easy!

Hello everybody,

thank you for your many answers here in the forum!
I ordered an SD49225T-HN (Aliexpress) to Germany and paid a total of 360, - Euro.
Unfortunately I only saw after the order that the SD49225T-HN has no auto-tracking function. So I ordered now a sd59225u-hni.
So if someone is interested in a brand new SD49225T-HN, then I sell mine for a good price. Within Germany with shipping for 300, - Euros. Please write to me.

greetings
