In regards to EcoFlex, you might not be seeing the overall picture of where this technology can help.
Is energy efficiency a big drive for the end user when deciding what products they want? 99% of the time I would argue no. Where this technology is going to change things, is that it enables the POE lock to exist more than just on paper or as a future talking point. It is real, and the fact that we can now cram more and more power dependent technology into smaller and smaller infrastructure that can only be a good thing.
With the access control wireless lock being a defined future for access control, there are still occasions where security regulations will not allow the wireless with battery to be used. In this case, the traditional wired application is probably going to be dominated by the POE lock design. You mean I dont have to run wires from door to control room? I just plug into a nearby Ethernet outlet? Count me in.
