Very good

The only drawback is the limited number of presets (upto 6 only) which can be viewed through the App. although in previous version of Lechange, I managed to view all the presets made in NVR remotely. Hope you fix that soon. Thank you.

Easy to Use

Added two different models of Imou cameras with good streaming quality and worked well with iOS,even supporting face ID.

App can’t make it past the sign-up screen. I entered my email address, carefully letter by letter, and created a 12 character password consisting entirely of letters and numbers, and no matter what the app wouldn’t let me press the button to continue. There is no way to even start using the app. Worse than useless, it wasted my time.
