Greetings all. I've been testing motion capture on a grey-market Hikvision cube wired to a non-WAN connected Asus router. Images are written to usb drive on router. I want to connect it to main router (R7800 w/ Voxels latest) in order to continue capturing motion AND receive email alerts upon detections. Can't run cable from ipcam to the R7800, so it has to be wireless. Rather than using usb with the R7800, I'll spin up a Proxmox container for either NVR or ftp service. My question, given the issues with ipcams in general, and Hikvison in particular, is how to secure the camera on network (no connections to any external sites/servers) while having alerts sent and also access cam feed via local VPN server?
