You have only tested the entry level product, not the Pro series which supports lift control & very nice ZKBioSecurity 3.0 browser based software. This software supports multiple clients with no software install on the client PCs.
You have also totally ignored the InBio controllers which, in addition to wiegand / RS485 card readers, also support integrated biometrics, with the biometric template being storedin the controller, not in the edge (reader) device. These biometric readers can also be used for lift control.
The system is not limited to 26bit either, as you state. In fact it supports multiple wiegand formats & can even have differing bit streams for different users eg 26 bit & 37 bit from the same reader.
You mention no support for PoE, there is an option to purchase the controllers in a bundle with PoE support. However PoE has limited usefulness in the access control world due to the current draw of many locking devices. Typically items like drop bolts have an inrush current of 1A (at 12VDC). This means a double doors could draw 24 Watts on initial lock.
