Resource Center
Two files are free to download without a form: the product guide and the model matrix. Everything else — model datasheets, test reports, manuals — we send by email, because the right version depends on which model and which revision your project is quoting.
The PoE range in one document: 70 PoE models across switches, extenders, splitters and injectors, with ports, uplinks, budgets, wire pairs and dimensions for each. Includes a page on how to read the power budget and PoE class columns.
Every model as a spreadsheet row with all specification columns, ready to drop into an RFQ, a bill of materials or a comparison against another supplier. Opens in Excel, Numbers or Google Sheets.
The guide is generated directly from the same product database that drives this website, so the PDF and the model pages cannot drift apart. Each of the 90 models appears with its powered port count, uplink configuration, PoE standard, power supply, wire pairs and — where they are published — dimensions.
It is split by family rather than by page order: switches first, then extenders, then splitters, then injectors. Each family opens with a sentence on what the columns mean for that product type, because the same word does not always mean the same thing — “power” on a switch is a shared supply, while “power” on an extender is the maximum it will pass through to one port.
The closing page explains how to read the numbers: why the budget is a pool and not a per-port allowance, what af, at and bt actually cap, why cascading extenders eats margin, and why a splitter's output must be matched to the device label rather than the switch.
If you are comparing us against another supplier, the CSV is usually faster: it puts every model on one line, so a column-by-column diff against their sheet takes minutes rather than an afternoon of PDF reading.
Power Design
Port count is the number people quote and the budget is the number that actually limits the site. A worked method for sizing PoE switches, with the arithmetic for af, at and bt classes.
Standards
The three PoE generations differ in voltage headroom, current, and how many pairs carry power. What that means when a camera refuses to boot or reboots at night.
Long Distance
Copper channels stop at 100 m. The three ways around it differ in cost, power loss and failure modes — and only one of them keeps the camera on the same PoE budget.
Selection
12 V domes, 5 V access units, 24 V PTZ heads — the splitter has to match the device, not the switch. How to read the label and avoid the two failure modes that get blamed on the camera.
Retrofit
Adding powered cameras to a building with a plain switch does not always mean replacing the switch. Where injectors win, where they stop making sense, and what the cable plant has to support.
