If you have, or are willing to get a router that has VPN capabilities built in, that is a very easy way to get the benefits and security of operating through a VPN. Having that set up enables a lot of other nice features as well, such as being able to securely access the internet, from anywhere, even over unsecured WiFi systems (hotels, airports, etc.) through the encrypted tunnel to your home network, and then through your home internet connection.
Many of us are using Asus routers with these features built in, and it is easy to set up and completely free to use. I can surf the net, access my cameras, and even use printers on my home network from anywhere through the VPN from our phones or PCs at work, etc. I highly recommend this.
The
Blue Iris UI3, using Chrome, from all of our gadgets, allows excellent and easy access to live viewing, clips, alerts, etc. It's great! And no ports need to be exposed. Highly recommended!
Edit to add: The VPN setup also lets the BI app work from outside of our LAN just great, too, and all without exposing any ports, etc.
