If you only have one camera you could be okay, running two 720 mjpeg streams over usb2 can be quite problematic ;) Do you know what codec and resolution is in use? What about the lag? What model of camera? I'm curious because my CCTV journey has been over a few years, and there has obviously been kernel and distro improvements. I did use the MotionEyeOS distro with an internal camera last summer briefly (a fortnight), but it didn't fit my use case very well.
