I have recently purchased 3 add in stand alone cameras like you have. Having a few issues with motion detection for the outdoor cameras. FYI I’ve reset all outdoor cameras and called the tech support no help by the way. I’m strongly considering buying the 2 Cam dvr like yours to see if it works better. Checking my cameras thru the day is cool in all but motion detection is what’s most important to me.
