Size a UniFi system before the cabling truck rolls.
Six free calculators — Protect storage, WiFi coverage, PoE & UPS, VLANs, cable runs, and project budget. Each one bookmarkable, each one shareable, each one grounded in how these systems actually get sized on real jobs.
No registration, no email wall, no popup overlays. If a calculator is wrong, it's wrong; we'd rather hear about it than hide it behind a form.
Why these exist
The same spreadsheets, made shareable.
UniFi sizing comes down to four questions: how many APs, how much storage, how much PoE, and what it actually costs. These calculators answer them in the open — no spreadsheet to hunt down, no quote to wait for.
The math behind these is open: bitrate × hours × cameras × retention, AP spacing against wall loss, PoE budget per switch. Run it, copy it, sanity-check a quote with it. What we sell is the next part — turning the numbers into a network we install, document, and stand behind so your team knows what was put in and how it's connected.
If you're a peer engineer sizing a job, take what you need. If you're a facilities lead trying to sanity-check a quote, share the URL with your installer. If you're looking at one of these for a real project and want it backed by a written plan, BoM, and warranty — that's what we do for a living.
What’s in the toolkit
Storage and RF carry most of the load. The other four catch the edge cases we used to re-derive on every job.
Right-size your UniFi Protect storage before you buy a single drive.
Per-camera bitrate × retention × motion vs. continuous, run against the real UNVR / UNVR Pro / Cloud Key bay counts and drive prices from real jobs. Saves the painful mid-deployment "we need another NVR" call.
Project cost estimator
Realistic budget for a UniFi install — equipment, drops, racks, labor, contingency. Itemized line by line so you can hand it to anyone.
WiFi coverage calculator
AP count and spacing for a real building, not a rectangle. Wall material attenuation, device density, capacity headroom.
VLAN & subnet planner
Best-practice VLAN segmentation and IP plan, exportable straight into the UniFi controller.
PoE & UPS planner
Per-switch PoE budget, UPS runtime sizing, headroom checks. The math behind every switch order.
Cable length calculator
Footage, boxes, patch panels per zone. TIA-568 channel limits respected by default.
Want this turned into a written plan, BoM, and warranty?
The calculators give you the numbers. We turn them into a network you can hand off and run — a site walk, a coverage plan, a scoped quote, the install, and a report when we leave that tells your team what’s there and how it’s wired. Work is hourly at one flat rate, two-hour minimum on-site across the New York tri-state area.
