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!
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.
