I noticed about 3 or 4 weeks ago I stopped getting IVS triggers in BI for IVS rules I had using using for the last year. Everything was working but now no more BI alerts for IVS triggers. The only thing I can think of is that BI version was updated about 3 or 4 weeks ago. None of the settings in BI or the Dahua cams were changed in the last 8 months.
So, I updated the BI5 software then it broke the IVS and now my BI5 maintenance is expired...LOL. Ah man, I should just crawl back under my rock for a little while longer.
