The camera works fine. I would give the camera alone a 4 star rating. However, since using the camera relies heavily on the app, it gets 2 stars. So the camera responds fast when you click on it in the app. Watching live feed is also good. The issues are a big language barrier when trying to get customer support. There are no explanations or instructions for the app. The first couple days there were "motion alerts" on the playback timeline. Now the timeline is blank, other than just watching the whole feed with no idea of when activity was recorded. It's using an sd card and recording 24/7. I have restarted the camera, deleted and added the camera and keep formatting the card and still not getting the proper timeline. A friend bought the same camera 3 days later and experienced the exact problems. I tried to sign up for 7 day cloud trial and I just get a buffering type of icon with a "0%" and then I have to exit the app to get back to normal. I tried contacting support via a message service in the app. I received a notification about an hour later. When I clicked it, it disappeared and there was no way to see what the reply was. Also, it does not appear that one can receive an alert notice for motion detection, click it and go straight to that video. You need to scroll through the timeline and look for red or blue indicators (when it works the first couple days). Customer service could be improved with a US based customer support for the app. I wouldn't recommend this camera because of the app.
