One New Jersey team for every system in the building.
A New Jersey security and low-voltage contractor. We do all four trades ourselves so there is nobody to hand the problem to when something stops working.
A security integrator built around accountability.

Legion E-Solutions · Newark · Jersey City · Elizabeth
Legion E-Solutions is a New Jersey security and low-voltage contractor run by Jonathan Diaz. We handle the systems that decide who gets into a building, what gets recorded, and what all of it runs on.
The reason we do all four trades in house is unglamorous. On too many jobs the cameras were one company, the cabling was another, the alarm was a third, and when something stopped working each one was confident it was somebody else's fault. Owning access control, cameras, cabling and low-voltage ourselves removes that argument entirely.
Most of our jobs come from buildings we've already worked in, or from a property manager passing our number along. That only keeps happening if the work holds up, so we build it to.
Build systems well enough that the building never has to think about them, and be easy to reach on the day it does.
What makes us different.
All four trades in house
Cameras, cabling, access and alarms are the same crew. Nothing falls in the gap between two contractors because there isn't one.
Crews based here
We work out of the Newark, Jersey City and Elizabeth corridor. You get a technician who's been in buildings like yours, not a dispatcher three states away.
Documented as we go
Labeled panels, tested terminations, certification reports handed over at closeout. Whoever inherits the system can read it.
Reachable afterward
Maintenance, remote support, and someone who answers when a door controller quits on a Sunday.
Four low-voltage disciplines, one team.
The values behind every install.
Say the real number
The quote is what it costs. If we miss something on the walkthrough, that's our problem to eat, not a change order to spring on you.
Finish the hidden parts
Nobody inspects the inside of a backbox. We dress it anyway, because the person who opens it in five years might be us.
Pick up the phone
You get a person who knows your building, not a ticket number and a callback window.
Don't oversell
If you need six cameras, we'll quote six. Talking someone into thirty is how you lose the next three jobs.
Credentials you can verify.
