I posted this as a reply on another thread, but I'll list it separately also.
I have basic GoKit in a 22" Toolbox I purchased at Walmart. This is my 3rd time (Ver 3.0) doing this and previously used a 20" box that just needed a bit more room.
Inside is stored a Polycom VVX-110 phone and 12vDC PoE HikVision 12mm lense camera, along with some lengths of ethernet, and V-LAN switch. To power it, I use a PowerWerx PowerBox with 20ah LiFeP04 battery. If the need arises, I have a power cable with small clamps on the end to connect to any available battery. Also have a TP-Link wireless Access Point to connect if needed, but I usually connect my laptop via ethernet as it's older and still has a port.
The computer is not part of the kit but is ready to go in a separate bag with 12v DC adapter to run from a battery.
Version 2.0 is described in the attached document and is in a smaller 20" box.
My Color Coding I chose for PoE is 12vDC (RED), 24vDC (Blue), 48v DC (Yellow)(For PolyCom VoIP phone).
