I just purchased Blue Iris. I purchased it to evaluate it as compared to an NVR. Currently, I have a Dahua NVR up and running. I can access all of my cameras from this NVR on the internet, and everything is working great. I only have to forward port 37777 to view my cameras, and port 554 to see recorded video. But, it looks like I will have to forward ports for every camera t gain the same internet access from Blue Iris. Is this true?
