I purchased 4 of their cameras to cover each side of our home. When the app works, the app works well. However, there is still quite a few issues when using an SD card. Random dropouts and errors when trying to watch events. Sometimes the cameras freeze when watching live. Purchased a brand new $200 mesh wifi system to make sure it wasn't my connection. It helped but didn't eliminate issues. They offer a cloud service but I feel if they can't make it work with SD why would I pay monthly?

On the surface and when everything works as it should, this is a very nice app for decent cameras. Somewhere along the line, the ball is dropped severely. Events being recorded tend to have seconds/chunks of time missing. Entire events aren't recorded that are blatantly obvious. Stuff you actually want to see wasn't recorded or is corrupt. It's unclear if the cameras OR the app is the problem, but none of these issues are solved with the cloud service either. Poor implementation.

Good picture. Good night vision. Top notch customer service. They try their best to help out. 3 stars is because I would like to be able to view cameras on something else besides mobile app. Also seen lots of reviews complaining about wifi connectivity, remote viewing etc. Had same issues. It's not the camera, it's your wifi connection. Maybe too restricted. Tried on a couple non restricted wifi networks. Worked flawlessly every time.
