I'm new to the world of 2Gig and recently received my Control Panel 2GIG-CP21. It comes with a 120v AC adapter to 14v DC adapter/transformer that plugs into the wall. When I called Customer Service they told me that there's no way to hardwire the control panel and that because of the transformer, it has to be plugged into the wall outlet. In my opinion, this looks extremely cheap. Are they correct that there's no way to conceal the wires in the wall?
