Finally a decent (not super, but pretty good for the money) wifi doorbell camera for use with my existing NVR software.
Unbranded Hikvision DS-6003 from a reputable U.S. source $149 U.S. Can be had cheaper from China if you shop around
Better video quality, smaller and cheaper than the crappy Ring. No subscription required.
Onvif compatible so it works with most NVR software.
32GB card.
Powered by existing doorbell wiring.
Mobile app is rumored to be pretty crappy, but will likely improve over time.
