Ordered 2 to replace a couple Ring camera's. One set up the lights didn't work. Threw some diagnosis, we found it was just a bad unit(camera worked just no lights). Logitech without blinking an eye sent out another. 
 The video quality during the day or night are awesome, and the notification are way better than ring ever was. I would recommend these to anyone and everyone. 

Keep up the great work Lorex.
