Best Residential Security System - No $ budget

[olsenblane 0]

Currently have a LaView (Hikvision) NVR and cameras (8 ch). I need something bigger and want a more advanced NVR. I've heard Hikvision is using some new AI capabilities in some of their cameras. What is the best NVR out there that meets some of these requirements:

 

- Min 16 channels (built-in POE)

- 4k

- Audio from camera's

- All Cameras will be outdoors

- Mobile Apps

- Ideally integrate with Home Automation (SmartThings, Echo, IFTT).

- Be able to use current Hikvision camera's

 

After researching online, I just can't find "the best" solution. (I realize that is a loaded question, based on opinions).
