- All cameras NOT viewed in Blue iris (with note: No signal & HTTP: 12002 Timeout), But i can viewed to direct by Chrome or IE or Firefox it ok. (EX: trang...ddns.net:1041 ---> it OK).
- i attached files: h1 + h2 's Amcrest model 721s, viewed ok on Blue iris ; h3 's Amcrest model 841, No signal on Blue iris.

Hi, you say you installed Blue Iris v4 and it does look like v4. Are you aware that BI4 is rather old ? Are you wanting the present version = V5 ? It might well work with your cameras and there is a demo version available.

I'm hoping somebody hasn't charged you money for v4

i bought blue iris.
Tks!

If that is recent, it will be for BI5. Please check.
