Fantastic functionality and easy to use.

This ptz camera system is excellent. I've used many systems professionally in the past. This home system is on par with many far more expensive setups regarding functionality, ease of use and variety of features. Picture quality is crisp and the app and NVR is easy to set up and use!

System worked great for 8 months, then began having trouble connecting with one camera... then all cameras... then couldn't connect to the keyboard for troubleshooting. You only get a 90 day warranty, so be warned. It's a lot of money for such a short warranty.
