LowVoltCalc: field calculators for low-voltage installers
A free set of calculators for planning low-voltage and security installations, covering voltage drop, camera systems, PoE budgets, batteries, conduit fill, and cable runs.
- For
- Low-voltage and security installers
- Worth noticing
- The camera IP planner exports CSV and cites RFC 950, 4632, and 1918.
Field notes
The visible voltage-drop form asks for supply voltage, load, one-way run length, wire size, and the device's minimum voltage, then offers a link to the full calculator. Other tool descriptions specify practical checks such as PoE cable loss and over-class flags, battery loads separated by system type, and conduit capacity based on real cable diameter. The homepage names standards and tables as sources; the extracted text does not expose the calculation formulas.
