The office
Fountain Valley, Since 1987

Why JMG
Five Things A Manufacturer Cannot Sell You
Equipment can be bought from anyone. These five are the reasons clients stay with JMG for decades.
01
Our own network
JMGCONNEX
A private, self-healing mesh radio on JMG's own FCC and UL licence, so no third party sits in the signal path.
02
By design
Vendor-Neutral
We manufacture nothing. We design with 19 manufacturers, so the recommendation fits your building.
03
Not subcontractors
Our Own Field Teams
Same people, same standard, same paperwork, in every Southern California region.
04
One place to work
Every System On One Screen
Doors, cameras, alarms and fire reached from the same place, so an incident is one story rather than three.
05
See it working
The JMG Command Center
A demonstration facility at the Fountain Valley headquarters, where several manufacturers' technology runs live.
