SafetyCalc Free

Free tool without advertising for installers of security systems

SafetyCalc - is a free tool without advertising that help all designer and installer of security systems and low voltage systems.

If you need to determine the workability of a branched low-current circuit, calculate the capacity of the power supply and battery systems for the access control system, calculate the camera's objective lens

for surveillance video systems, this application for you.

SafetyCalc features :

- Calculation of the voltage drop in a branched electric circuit with many loads for each load, and to determine the minimum cable wire section;
