Security systems and cabling, done right.
Wired cameras, access control, intercoms, structured cabling, networking and AV, installed and repaired for homes and businesses across all five boroughs and the tri-state. One family-owned NYC shop. No guesswork, no shortcuts.
Full-service low-voltage solutions.
From a single camera to a full building build-out, we handle every part of your security and low-voltage infrastructure, start to finish. Installation and repair.
Security Cameras
Wired PoE and HD camera systems designed for your property. We handle placement, concealed cabling, NVR setup and remote mobile access, so you always know what is happening on site.
Access Control
Key fob, key card and smartphone entry for buildings, offices and secure areas. Control who enters, log every access event, and manage it all remotely.
Intercoms
Buzz-in, video and telephone-entry systems for apartment buildings, co-ops, brownstones and commercial entrances, with the door release handled in the same visit.
Structured Cabling
Organized, labeled and properly terminated network cabling for offices and commercial spaces. Clean runs, patch panels and infrastructure built to last and easy to expand.
Network Design
Wired network infrastructure designed for reliability. We deploy enterprise-grade switches, access points and routing, and configure everything for performance from day one.
Camera install pricing and process
See what a professional camera installation costs, what is included, and how it works, from consultation to completion. Transparent pricing, no surprises.
Something stopped working? We repair it.
Any brand, no matter who installed it. Most of our repair calls are on systems from companies long gone, with no paperwork and no password.
The Seneca difference.
We are not a national chain. We are a family-owned NYC company, and every job reflects it.
Apply to every job
Licensed and insured
Fully licensed in New York and New Jersey. Proper credentials and proper insurance, every job, every time.
Clean wiring, always
We take pride in concealed, organized cabling. No dangling wires and no zip-tie hacks. Work you would be proud to show a building inspector.
Wi-Fi jam-proof
We default to wired PoE cameras over Wi-Fi. Hardwired systems do not drop connections, cannot be jammed, and perform reliably for years.
No monthly fees
Your NVR records locally. No cloud subscription required. You own your footage, stored on site and viewable from your phone.
One-day installs
Most residential and small commercial installs are completed in a single day. We show up on time, get to work, and leave the space clean.
Ongoing support
We pick up the phone after the job is done. Questions, adjustments and expansions. We are your long-term partner, not a one-time contractor.
What our clients say.
Verified Google reviews from property managers, business owners and residents across NYC.
Seneca installed a full camera system for our 12-unit building and the work was immaculate. Every camera is perfectly positioned, the cabling is hidden, and the NVR is organized and labeled. Our tenants feel safer and the whole job was done in one day.
We needed cameras in our NYC office building on short notice. Seneca came out the same week, gave us a transparent proposal, and had everything up and running within two days. Professional from start to finish. Absolutely recommend.
These guys know what they're doing. They walked us through every camera placement before drilling a single hole. The setup was clean, they showed us how to use the app, and they checked back in a week later to make sure everything was good.
I own a retail store in Brooklyn and had been putting off cameras for years because every quote seemed overpriced. Seneca gave me a fair price, used quality equipment, and the system has been flawless for over a year. Wish I'd called them sooner.

Questions we hear first.
RFI log · requests for information
RFI-01What does a low-voltage contractor do?
We install and repair the systems that run on low-voltage wiring: security cameras, access control, intercoms, structured cabling, networking, and audio and video. One licensed shop for all six, instead of several separate trades.
RFI-02Do your camera systems have monthly fees?
No. Our camera systems record locally on an NVR at your property. You own your footage and view it from your phone, with no cloud subscription required.
RFI-03Do you repair systems you did not install?
Yes. Most of our repair work is on systems from installers who are long gone. You do not need the original paperwork, and in most cases you do not even need to know the brand.
RFI-04How long does an installation take?
Most residential and small commercial installs are completed in a single day. We show up on time, get to work, and leave the space clean.
RFI-05What areas do you serve?
All five NYC boroughs and North Jersey, including Jersey City, Newark, Hoboken, Bayonne and Fort Lee. We also serve Long Island and Westchester, and take selected jobs in Connecticut.
