Brooklyn Security Camera & Access Control Installation
Licensed Installs for Brownstones, Mixed-Use Buildings & Everything In Between

Security Systems for Brooklyn Homes & Businesses

Brooklyn's building stock creates installation challenges you won't find in newer construction. Pre-war brownstones and row houses typically have original plaster walls, finished ceilings with no attic access, and narrow utility chases that make cabling runs genuinely difficult. Getting wires from a ground-floor storefront up to a second-floor apartment — or fishing cable through three floors of a Bed-Stuy brownstone — requires patience, the right tools, and experience with how these buildings were actually built. Mixed-use buildings in Williamsburg and DUMBO add another layer of complexity, with commercial tenants on the ground floor and residential units above, often requiring separate access control zones and camera systems that serve both. We've worked in all of it, and we don't cut corners just because the run is tough.

Common Questions

FAQ — Brooklyn Security Installation

In most cases, yes — though we'll be straight with you about where it's genuinely difficult. We use flexible drill bits, fish tape, and wall cavity routing techniques developed specifically for plaster-and-lath construction. In some brownstones there's enough space through closets, utility chases, or along baseboard runs to get cameras placed where you need them without opening walls. We'll walk the property before we quote and tell you exactly what's realistic, including where we might need a small access point patched afterward.
A typical 4-camera wired PoE system on a single-family or two-family brownstone generally runs between $1,800 and $3,500 installed, depending on camera placement, how difficult the cabling runs are, and whether the building has a convenient location for the NVR and network equipment. Multi-family buildings or mixed-use properties with more entry points will run higher. We price per job after a walkthrough — not off a rate card — because Brooklyn buildings vary too much for a flat quote to mean anything.
For most low-voltage work in New York City, yes — especially in commercial properties or multi-unit buildings. The NYC Department of Buildings and Local Law 196 requirements mean that electrical and low-voltage work in commercial and multi-family buildings needs to be done by licensed contractors. Seneca Security holds the appropriate low-voltage licenses for New York, so your installation is code-compliant and won't create headaches if you sell the building or need a certificate of occupancy inspection.
