Not at all. I bought the packaged system ( IP access system) from Essex Electronics. All I had to do was run an Ethernet cable and purchase a relay that fired back to the
Washworld UCC cabinet. The basic components are built by HID and is based on their Edge Solo system. If you need any more specifics, please feel free to email me.
FYI-the only drawback to the system as designed is that it is schedule based and not number of entry based system which is why the subscription platform is damn near impossible to set up.
