New York Metro · Long Island Gold Coast, New York
Smart Home, Lighting & AV on the Long Island Gold Coast.
Three acres, a guest house, a pool house, and a drive long enough to need its own lighting plan. Estates on Long Island's North Shore are campuses, and the technology has to reach every building and every corner of the grounds.
Long Island Gold Coast, Specifically
An Estate Is a Campus.
The Gold Coast was built as country estates: more than 500 mansions went up on the North Shore from the 1890s, concentrated in about 70 square miles, and Sands Point was the model for the East Egg of The Great Gatsby. Many estates were later subdivided, but the villages kept large-lot zoning; Old Westbury still requires three acres in its largest residential district.
On a property like that, the house is one building among several. The network has to reach a guest house and a garage by fiber, the cameras have to cover a long drive and a tree line, and the landscape lighting, gate, and pool equipment all belong in the same system as the rooms inside.
01 · Network
Fiber Between Buildings
Wi-Fi does not cross a lawn reliably. We run fiber between the main house, guest house, garage, and pool house, put a UniFi switch in each, and design outdoor coverage for the terrace, the pool, and the court.
02 · Grounds
The Gate, the Drive, the Tree Line
Long drives and wooded edges need cameras placed for the approach, not the house. We plan buried conduit for cameras, landscape lighting, outdoor audio, and the gate intercom before the site work closes, and we tie it all to one control system.
03 · Power
Ride Through the Outage
When a storm takes the lines down, the standby generator carries the house and battery backup carries the network and control system through the transfer. We size both for the rack, the gate, and the security system, not just the refrigerator.
At a Glance
Long Island Gold Coast in brief.
- History
- Beginning in the early 1890s, more than 500 mansions were built on Long Island's North Shore, concentrated in about 70 square miles; Sands Point and Kings Point were the models for East Egg and West Egg in The Great Gatsby.
- Zoning
- In Old Westbury's B-4 residence district no lot may be smaller than three acres, with side and rear yards of at least 100 feet; the BB district allows one family per two acres.
- Electric utility
- PSEG Long Island has operated the Long Island Power Authority's electric grid under a management contract since January 1, 2014, serving Nassau and Suffolk counties and the Rockaways.
- Internet
- Verizon Fios fiber and Optimum both serve Old Westbury, with availability varying by street, so we confirm service at the address before designing the network.

Long Island Gold Coast, Answered
Who installs Lutron and Crestron systems on Long Island's Gold Coast?+–
Cave Group does. We are a Crestron Elite Gold Partner and Lutron Gold Dealer with a New York office in Long Island City, and we design, install, and service lighting control, shades, cinema, audio, networking, and security for estates in Old Westbury, Sands Point, Muttontown, Brookville, Oyster Bay Cove, and the villages around them.
Can one system run the main house, the guest house, and the grounds?+–
Yes, and it should. We connect the buildings with fiber, put the lighting, shades, audio, cameras, gate, and landscape lighting on one Lutron and Crestron system, and give you one app and one set of keypads for all of it. It is far easier to plan while the site work is open than after the landscaping is finished.
How do you keep the systems running through a storm?+–
A standby generator carries the house, and battery backup carries the network, control processor, and security system through the few seconds of transfer and any generator start-up problem. We monitor the system remotely, so we know when the power drops and when it comes back.
Do you take over systems another company installed?+–
Yes. We assess and document what is there, recover or rebuild the programming, replace what has reached end of life, and bring the system under a Cave Watch support plan, so the next problem has a phone number.
Do you support the system after installation?+–
We do. Cave Watch is our support program: round-the-clock remote monitoring of the network, control system, audio-video, and lighting, remote fixes and software updates, priority response, and an annual health check. Central-station alarm monitoring and live guard video monitoring can be added to the same plan.
