We're not a national chain. We're a family-owned NYC company — and every job reflects it.
Licensed & Insured
Fully licensed in New York, New Jersey, and Connecticut. Proper credentials, proper insurance — every job, every time.
Clean Wiring Always
We take pride in concealed, organized cabling. No dangling wires, no zip-tie hacks. Work you'd be proud to show a building inspector.
Wi-Fi Jam-Proof
We default to wired PoE cameras over Wi-Fi. Hardwired systems don't drop connections, can't 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 accessible 24/7 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, expansions — we're your long-term security 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."
