IMHO, Balance Two would be good choice (note Two has a lot more internal throughput capacity than One), and give you room to grow. You’re likely to be far more limited by current WAN bandwidth than the Peplink at this point. Those internal IP cameras can use the Balance for DHCP, and a few outward streams, but I’d use switches to keep most that traffic off the router. If situation changes, pushing 80 streams is going to need a far more cu$tomized solution. Also, Ubiquiti has been slow to go to WiFi 6 - I’m slowly upgrading my Pepwaves now to AX. May want to include a few of those in the deployment, especially to dense areas. Extra antennas help a lot if you have 20+ users on a node. I think the 30 is little tighter - you might be OK now, but not much room for growth, and bandwidth needs only go in one direction. (We do around 200GB daily over the WAN, not a lot of LAN specific transfer).
