I bought a couple of these cameras with NVR and very happy. Pros - Price - great value for money - Video - high quality (not 4K but don't need it) - Stable - the connection is very stable, doesn't disconnect, we use it as a baby monitor and never disappointed us - Audio - good audio - Works well with NVR - Supports Google Home integration (but not if connected to the NVR) Cons - Viewing Angle - it's quite narrow but as advertised so no surprises here
