Okay. Got mine in and started messing with it. Somewhat of an infuriating thing to get configured. Lechange is pretty much mandatory to at least get it initially configured. They have a Windows desktop version which is worse than the stupid app. The desktop version is pretty much useless so do not bother. I'm using a wired connection so your results may differ. Tip - setting up the camera in the app on your phone is easier when you scan the QR code, the tip, there is a duplicate code on the box. Some caveats. As mentioned, a couple of things can ONLY be configured via the app like Smart Track and turning the light ring on/off. You do not have to subscribe to their cloud service. You CAN get the web interface back but it is complicated. You have to physically open it up and use a serial TTL connection to some spots on the circuit board inside. If you REALLY want to do this, read up in the unbricking your Dahua IPC thread on here and find out what all you need. Two of the feet have screws under them, then use a plastic wedge to carefully snap the bottom off. I have the web files from the older firmware and copied them to the device via serial connection and they took just fine. That being said, the web interface, just like anything but the app, also does not have the ability to turn the light on/off nor turn Smart Track on/off.
If I coudl just be able to control those two things via SmartPSS or through my NVR I'd be happy. Another tip, if you add or mess with the default password in the web interface or anywhere other than the app, the next time you open the app it will hammer it and lock the account out. The only fix is to remove it from the app and then add it again - they give you no where in the app to change that. Maybe the smug, I mean Apple
version of the app is different (I have a Motorola phone). It seems that they have not done anything consistent for these across ways of using them.
Its an interesting device and I think it can even be viable for commercial use if you plan for its limitations ahead of time since in commercial settings (and many others) once a camera is truly configured and setup, it is rarely messed with anymore. So its pretty much configure it with Lechange, decide if you want the cute light ring on, and decide if you want Smart Track on. I plan on force stopping and disabling Lechange on my phone but I'll leave it installed and re-enable it if I want to change one of those two things.
