What alarm company to rich people and movie stars use?
Typically it would have at least one router, one switch/hub and possibly a firewall appliance. Media, can be anything from Cat5e through Fibre Channel, just pick one for all of it.
Car alarms are yesterdays news. Get an immobilizer. Master lock do a decent killswitch. People just ignore alarms. They go off at the drop of a hat. Factory fitted are OK. Secondary fitted often junk.
