Who makes appliances lets you run your choice of VMS software with integrated analog encoding and IP camera support. Bonus points if the appliance also supports HD analog.
Perhaps the closest analogy would be Razberi except that Razberi is an open VMS appliance with an integrated PoE switch but not integrated analog encoding.
Any suggestions? We see this request come up periodically as users wants a higher-end VMS but the simplicity of a single unit that can handle existing analog cameras or re-using coaxial cable for HD analog cameras.
