yeah in usa switches are so cheap. here in europe you pay 500-1000€€ for 10y old poe switch.
FYI: I finally got my IVS to work with BI for the color4k-T180. and the "Event Subs" went away. I followed @wittaj instruction on reset 3, update FM, reset 3.Well it look as if part of the issue may hve been a dying switch. Both cameras are no longer contactable ffrom any pc althought the switch continues to show green. Just get timeouts with any browser and cameras won't show or add in BI. Time for a new switch. That one lasted all of 3 weeks!!!
My takeaway here is don't buy TP Link but maybe I was just unlucky.
I foresee a Netgear on the horizon and I might not case it just to be sure although the air in the garage gets damp in winter so it's horses for courses heat vs damp.
