Cellar to roof deck, one wired system.
Townhouses have several exposed facades, street-level entries, private rear gardens and three or four finished floors. We design and install wired PoE camera systems for the geometry of NYC townhouses: pre-war masonry, finished parlor floors, roof terraces and everything in between.
Floors pulled apart to show every level. Coverage is planned in this order: entries, stairs, then outdoor zones.
Townhouses are not just bigger apartments.
They are vertical, multi-entry buildings with party walls, private outdoor space and construction quirks that call for a careful low-voltage approach.
Multi-floor vertical coverage
A four-story townhouse has stairwells, landings and floor-by-floor entry points that one camera cannot cover. We plan placement floor by floor for continuous coverage from cellar to roof, with no blind spots on the stair runs.
Street-facing and parlor-floor entrances
Most NYC townhouses have a garden-level service entrance and a raised parlor-floor front door on the same facade. Cameras capture clear, face-level footage at each, accounting for stoops, ironwork and recessed doorways.
Private rear gardens and carriage access
Rear yards and carriage-house garages are common ways in that often go unwatched. Weatherproof PoE cable reaches the garden perimeter, the rear door threshold and any shared alley, which matters on blocks where rear fences meet the neighbors.
Pre-war masonry and plaster walls
A 100-year-old townhouse means thick masonry, horsehair plaster and sometimes landmarked interior details. We use low-impact fishing techniques that keep finishes intact. Every penetration we make through a fire-rated wall or floor is fire-stopped.
NVR placement and network infrastructure
The recorder needs a logical home: a utility closet, a cellar mechanical room or a dedicated IT panel. We work with your existing network or build a dedicated VLAN for camera traffic, so remote viewing works without exposing the recorder to general household traffic.
Household staff and service access
Housekeepers, nannies, dog walkers and contractors come and go. A zoned system with time-stamped remote viewing lets you check arrival and departure times, watch package deliveries and keep a record of who reached which floor, without a building super.
Who came in, when, and which floor they reached.
Tap an event to see the alert and clip the way the owner sees them from a second home.
The housekeeper arrives at 09:02. The garden-level door camera sends the alert, and the clip is on your recorder with the time stamp.
A courier leaves a package on the stoop. The entry camera is set for the deep stoop, so the face and the box are both readable.
The dog walker comes in at 12:05 and leaves at 12:48. Arrival and departure are both on the log, without a building super to ask.
A contractor is on the third floor landing at 14:30. Landing cameras show who reached which floor, and when.
Townhouse camera system components.
Every component is commercial-grade, wired through PoE and recorded on a single NVR for central recording and remote access.
Wired PoE IP cameras
Cat6 · PoEOne Cat6 run delivers power and data to each camera. No separate power supplies and no Wi-Fi dropouts: the right choice where reliable long-term recording matters more than easy DIY setup.
4K and high-resolution turret cameras
Turret · flush mountTurrets mount flush to masonry or trim with minimal protrusion, the right choice for landmarked facades or detail-sensitive interiors where a dome or bullet would look out of place.
Wide-angle doorbell and entry cameras
Parlor and garden doorsDedicated entry cameras at the parlor-floor and garden-level doors capture license plates, faces and package deliveries with correct exposure, which matters on deep stoops where light contrast is extreme.
PTZ cameras for roof decks and gardens
Pan · tilt · zoomPan-tilt-zoom cameras on roof terraces or in rear gardens follow motion across a wide outdoor space without a dense grid of fixed cameras. Useful when the garden is large.
NVR recorders with local storage
Redundant HDD baysRecorders with redundant drive bays store continuous or motion-triggered footage on site, with no cloud subscription. Remote access runs through a secure app.
Structured cabling and conduit
Raceway · conduit · fishedHome runs in surface raceway, in-wall conduit or fished through existing cavities, depending on how sensitive the finish is. Every penetration through a fire-rated wall or floor is fire-stopped, and cable paths are documented for future service.
Our townhouse installation process.
From the first walkthrough to live remote viewing, this is what to expect.
On-site assessment
We walk every floor, cellar to roof, mapping entry points, existing conduit, the electrical panel and your network. We note masonry obstacles, finishes to protect and any landmark or co-op board limits on exterior work. You get a written scope and proposal before any work begins.
Camera layout and NVR design
A placement plan showing fields of view, home-run paths, recorder location and network integration. On multi-floor townhouses we prioritize entries first, then interior stairwells, then outdoor zones. You approve the layout before we schedule.
Wired installation
Our technicians run Cat6 from each camera position back to the recorder, fishing through walls where possible and using paintable raceway where not. Exterior penetrations are weatherproofed and sealed, and cameras are mounted, aimed and addressed before the recorder is configured.
NVR configuration and handoff
Motion zones, recording schedules and retention suited to your storage. Remote viewing is set up on your phone or tablet before we leave, and we walk you through playback, clip export and adding accounts for family members or property managers.

RFI log · requests for information
RFI-TH1How many cameras does a typical NYC townhouse need?
Most four- to five-story townhouses land between 8 and 14 cameras, depending on entry points, floor count, outdoor space and whether interior stairwells are included. A standard layout covers the parlor-floor front door, the garden-level front door, the rear garden door, the rear yard perimeter and interior landings on key floors. Square footage alone does not set the count; the geometry and the number of entry points do.
RFI-TH2Will running cable damage my townhouse's historic plaster or woodwork?
Not when it is done correctly. Pre-war townhouses have thick plaster and ornate woodwork that deserve respect. We use flexible drill bits to fish cable through wall cavities and stud bays wherever possible, avoiding surface cuts. Where fishing is not feasible, especially on parlor floors with high-relief moldings, we use slim paintable raceway that can be color-matched and is far less disruptive than an open channel. We agree on the approach for each run during the assessment, before anything is touched.
RFI-TH3Do I need DOB permits for a residential townhouse camera installation?
Camera cabling is low-voltage work and does not need a DOB electrical permit. Every penetration we make through a fire-rated wall or floor is fire-stopped. In a landmarked building or historic district, exterior camera mounts and conduit may still need Landmarks Preservation Commission approval. That includes brackets on the facade, so we suggest mounting positions that keep exterior hardware out of view. Seneca Security is licensed and insured in New York and New Jersey.
RFI-TH4Can I view my cameras remotely when I am traveling or at a second home?
Yes. Every recorder we install supports remote viewing through a mobile app over your home internet. You can watch live, review recorded footage and get motion alerts from anywhere. We set up remote access during installation and test it on your device before we leave. For owners who split time between NYC and another home, this is a main reason to choose a wired recorder over a cloud-subscription camera: the footage stays on your recorder, not on a third-party server.
RFI-TH5My townhouse has a finished basement and a roof terrace. Can cameras cover both?
Yes. Cellar and rooftop coverage are both standard on townhouse installs. Below grade, we usually cover the bulkhead or egress window wells that present the most risk. On a roof terrace, we mount weatherproof cameras on parapet walls or existing structures, using penetration methods suited to the roof membrane. Every camera, from cellar to roof deck, runs home to the central recorder, so it is one system with one set of recordings and one remote login.
RFI-TH6How long does a full townhouse camera installation take?
It depends on the camera count, the number of floors and how much cable runs through plaster. A small exterior-only system on a straightforward building is a much shorter job than a 12-camera system with interior runs on every floor. The proposal includes a realistic schedule for your building, and we plan the work so you are not managing an open-ended job site.
