From a single camera to a full building build-out, one licensed and insured NYC team handles every low-voltage system in your property, including the ones someone else put in.

Most jobs need more than one system.
One company plans them together, so they share cable runs, power and one network, and one team answers for all of it.
Apartment building entrance
Residents use fobs, visitors use the intercom, and cameras watch the lobby and the door.
New office or floor
Cable first, then the network, the conference rooms and the doors, planned as one job.
Store or restaurant
Cameras on the register and the door, solid Wi-Fi for POS and guests, music in every zone.
Elevator cab upgrade
A working cab phone line, a camera in the cab, and readers with floor lockout, coordinated with your elevator contractor.
Something not working? Start with the symptom.
Each guide explains what usually causes it and how we fix it, on any brand.
All repair services →Beyond install and repair.
Jobs that cross every system or do not fit under one label. These are often the first call.
Is your brand covered?
A representative sample. We service brands that shipped from the mid-1990s onward, across all six systems, whoever installed them.
Text a photo of the equipment label to 646-838-2300 and we will tell you if we can service it.
How it works.
Simple, clear and no surprises. This is what working with Seneca Security looks like, from first contact to finished install.
Free consultation
We look at your property, talk through your goals, and find coverage gaps or infrastructure needs before recommending anything.
Clear proposal
An itemized quote with scope and pricing. No bundled fees and no vague estimates, just a proposal you can approve with confidence.
Professional install
Clean work, with every component set up (cameras, recorders, access points or speakers) and fully tested before we leave.
Ongoing support
We stay available after the install: system questions, app help, adding cameras, growing your network.
What sets us apart.
Licensed, insured and accountable
Licensed and insured in New York and New Jersey, and held to the same standards on every job, residential or commercial.
Wired first, your footage stays yours
We prefer wired PoE for reliability: no Wi-Fi drops and no jamming. Camera recorders are local, so you are never forced into a cloud subscription to see your own footage.
Family-owned, NYC-based
Not a national franchise. A family-owned NYC company that has served the city for more than 10 years, and treats every property the way we would treat our own.
