Looking for suggestions for a outdoor WiFi camera with excellent motion detection, possibly with a PIR detection. Budget is under $200. Current setup is an AHD Hikvision wired camera. It does well but I have some very challenging lighting. We get fast moving clouds and my neighbor also has a big flag that casts a large shadow in the afternoon. I'd like something that has face detection alerting or a true motion detector. I'm looking at the nest outdoor as it seems to do face detection but I'd rather get something that plays nice with my Hikvision DVR that can accept IP cameras.
