About Us
15+ years protecting Philadelphia businesses
UDT SECURITY is a locally owned commercial low voltage contractor in Elkins Park, PA. The bulk of our work is commercial — offices, warehouses, retail, restaurants, houses of worship and multi-family properties — with residential projects handled to the same standard.
One contractor for every low voltage system
Most buildings end up with a camera company, a phone company, a cabling company and an alarm company — none of whom talk to each other. We do all six disciplines in-house, so your cameras, doors, network and phones are designed together and supported by one team.
That means fewer trips, fewer finger-pointing calls and a system that actually behaves like one system.

How we work
We walk the site first
No quote goes out from a floor plan alone. We look at sightlines, lighting, pathways and existing infrastructure before pricing anything.
Clean, documented work
Labeled cable, dressed racks, as-built documentation and credentials handed over to you — not held hostage.
Honest recommendations
If four cameras will do the job, we will not sell you twelve. If your internet cannot support VoIP, we say so first.
Local response
We are based in Elkins Park, minutes from Philadelphia. Businesses get a real technician on service calls, not a call center — including after-hours work when downtime is not an option.
