As I progress on building out my exterior Dahua/Blue Iris camera setup, I have not missed the fact that should someone get in without triggering an alert (or if I miss it), I'll have no idea what's going on. My first thought was to add a few interior cameras but I'm not sure about the WAF on that one. Costco has the $239 Ring Alarm kit in-store which is tempting. The alarm could tell me something's happening, but not what's happening without cameras.
