What We Do

Every low-voltage system in one contract

From a single camera to an integrated fire, intrusion and access system across a multi-building site.

Access Control & Intercom

Stop rekeying the building every time someone leaves

A lost key means a locksmith, new cylinders and new keys for everyone. A lost badge means one click. That single difference is why most commercial buildings move off keys and never go back.

  • Any credential — card, fob, PIN, or the phone already in their pocket. Add a contractor for a Tuesday and have it expire on Wednesday.
  • Who, where, and when — door groups, shift schedules and holiday calendars. The cleaners get the lobby at 6pm, not the server room at 2am.
  • A record of every door — every badge, every attempt, every forced or propped door, time-stamped and reportable. Useful for insurance, indispensable after an incident.
  • One-button lockdown — every exterior door secured from the front desk or a phone. For schools this is the whole reason the system exists.
  • Tied to the cameras — a badge event pulls the video from that door at that second, instead of scrubbing an hour of footage.
  • Unlock from anywhere — let a delivery or a service tech in from your phone without driving over.

Schools & Houses of Worship

Buildings full of people, open to the public

A campus or a congregation has a harder problem than most businesses: the doors are meant to be open, the population changes hour to hour, and the people inside are the reason the building exists. Deterrence, detection and response have to work together — and someone has to be watching when the building is empty, too.

Deterrence

Visible cameras, controlled entry points, perimeter coverage and posted signage. Most incidents are decided before anyone gets to a door.

Detection

Door position, motion, glass break and fire — plus after-hours video on the lots, the fence line and every entrance.

Response

Signals answered at the central station around the clock, verified where video allows it, and escalated to your people and to dispatch.

Built for the building

Classroom lockdown, all-call and intercom, mass notification, BDA/DAS coverage for responder radios, and inspections kept current.

Commercial & Industrial

Perimeters, yards, docks and everything inside the fence

Warehouses, terminals, plants and marinas have the hardest problem in the trade: a large outdoor footprint, people and vehicles moving through it all day, and high-value property sitting in the open — often on the water, where the perimeter has a side you can’t fence. The gate is the first line; the cameras and the central station are what make it mean something.

Perimeter & yard

Fence-line cameras, lot and dock coverage, lighting integration and after-hours video on everything outside the walls.

Gates & vehicle access

Controlled gate entry, credentials for drivers and contractors, and a record of who came through and when.

Marinas & waterfront

Dock and slip coverage, gangway and gate control for slip holders, fuel dock and boatyard cameras, and equipment rated for salt air.

The backbone

Structured cabling, fiber between buildings, rack build-outs and wireless coverage — the layer every other system runs on.

Request a Site Assessment Warehouses, distribution, terminals, manufacturing, contractor yards, marinas and boatyards.
State & Municipal

Public work has a second set of rules

On a municipal job the system is only half the deliverable. The other half is the paperwork behind it — prequalification, prevailing wage, submittals, code review, closeout documents and equipment that clears procurement restrictions. We work as a direct contractor and as a subcontractor to GCs on public projects across the tri-state area.

Municipal town hall and public works yard protected by monitored security systems, meeting bid, compliance and inspection requirements

Bid-ready

We read the spec, price to it, and submit what the package asks for — as prime or as a sub to your general contractor.

Code & compliance

Designed and installed to code, inspected by the AHJ, and documented so the file stands up on review.

NDAA-compliant equipment

Section 889 bars certain manufacturers from federally funded work. Being manufacturer-neutral means we spec to the restriction, not around it.

Inspection & service

Ongoing fire inspection, testing and central station reporting, with records kept current for the next walkthrough.
