Why JMG
Five Things A Manufacturer Cannot Sell You
Our own network
JMGCONNEX
A private, self-healing mesh radio. JMG holds its own FCC and UL licence, so no third party sits in the signal path.
By design
Vendor-Neutral
We manufacture nothing. We design with 19 manufacturers, so the recommendation fits your building.
Not subcontractors
Our Own Field Teams
JMG technicians work out of every Southern California region. Same people, same standard, same paperwork.
One place to work
Every System On One Screen
Doors, cameras, alarms and fire are reached from the same place, so an incident is one story rather than three.
See it working
The JMG Command Center
A demonstration facility where several manufacturers' technology runs live, so you watch it work before you buy it.
Case study
One job, in the order it happened: what was there, what we designed, what changed, and what is in place now.
"When I told the competing system providers what we needed and that it had to be installed in 12 weeks, only JMG had the confidence, capability and personnel to commit to that schedule."

JMGCONNEX
Your Alarm Signal Does Not Depend On A Phone Company.
JMG built its own private mesh radio network. It "will transmit signals even under extreme conditions such as earthquakes, flooding, and severe weather storms", and JMG holds "their own FCC and UL license, so there is no need to rely on a 3rd party."
