Why is there no touch screen hub for the Shield alarm hub?
Your smartphone or tablet is designed to be the primary method of interacting with the SCW Shield system. This is an intentional design choice. The things we didn't like about the "tablet on a wall" idea for alarms was that it increases the costs by usually using proprietary tablets, having limited screen size options, and the tablet was always in the wrong place. We always have our phones with us, so we started there.
You also use any tablet you want, and keep them anywhere you want, including mounted on the wall.
Lastly, we do have a touch screen panel that you can purchase.
