And here it is for a QC804: ~ # cat /proc/cpuinfo machine : hdk7108 processor : 0 cpu family : sh4 cpu type : STx7108 cut : 2.x cpu flags : fpu icbi synco fpchg cache type : split (harvard) icache size : 32KiB (2-way) dcache size : 32KiB (2-way) address sizes : 32 bits physical bogomips : 493.56 Pretty much the same. Does this tell us everything we might need to know about the hardware's channel capacity? Is there some video processing not identified by cpuinfo?

You might try user root, psw vizxv at the shell prompt. That got me into the WAN port on my QC804. It is probably the same going in through the LAN ports. I nosed around inside soon after I got it last fall. Found that most of the NVR behaviors are inside a single executable, making it hard to do any reverse engineering there. But the linux environment is there and might let you query the hardware configuration, especially identifying the processor, memory size, etc.
