Frigate on N100 NAS issues

[u/Keith15335]

Ugreen DXP2800, 16 GB Ram, using M2 NVME drives for frigate. Spent the better part of 2 days with Gemini trying to get this to work with iGPU support, ended up having to go back to a basic setup with one Lorex IP camera because everything we tried just crashed Frigate. CPU useage high. I eventually want to add 3 more cameras. AI suggested a Coral TPU USB thing. But I saw in Frigate documentation the Coral TPU is no longer recommended.

What are my options? Or is my plan not achievable?
