No comparison with all the functionality and saving to your own Hikvision NVR to Nest’s cloud storage which you constantly keep paying for and again gives you no functionality. If you don’t know how to properly set things up then the commercial Nest system is more for you. I’ve spent many hours reading and playing with all my settings, adjusting bandwidth and fine tuning the camera settings and I love my system. I’ve setup my cameras using the device connection and I get almost an instant connection every time. My wife was logging into her phone with my account instead of me sharing. I thought I had a problem with my Hik-Connect cloud account disappearing randomly from my phone but that was user error. My Hikvision NVR and cameras have never once crashed on me. There’s a reason why you setup dual streams. If your speed is not fast enough then you can’t stream high resolution. Nest cameras are no comparison to Hikvision. People simply don’t know what they’re doing. I am in shock reading all of these negative reviews but I think I know why.
