This is by far one of my most favorite customer installations. I designed everything about this system from the ground up to be exactly what was requested.
This rack controls:

Security Cameras
Alarm System
All the network runs to the rooms on all 3 floors.
The home phone lines.
The incoming internet.
Both of the outdoor stereo speaker sets for the patios.
And the living room home theater.
The most important equipment runs through an Uninterruptable Power Supply (UPS) to prevent critical components from losing power during an outage.

I was told by the homeowner to make everything as simple as possible to use. I made sure everything was clearly labeled with what every switch and button controlled.
This made figuring out how to control things very easy and the switch panels were installed to individually power cycle devices without having to remove any power plugs.

This system has been in place for a few years now and has been operating as expected with very happy customers.
