SafetyCalc Free

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 an branched low-current circuits, calculate capacity of the power supply and battery systems for access control systeml, 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 cabel wire section;
- Calculation of the voltage drop in a branched electric circuit with many loads for each load, if all of the loads connected to a common power bus with cable with various wire section ;
- Calculation of the voltage drop in a branched electric circuit with many loads for each load, if all of the loads connected to a common power bus with cable with the same wire section ;
- Calculation of the power supply and battery capacity for a access control system, for standby (8 hours) and alarm (3 hours) working mode;
- Calculation of the camera's objective lens for for surveillance video systems: determination of the vertical and horizontal focal length, definition viewing angle both vertically and horizontally, the definition of dead zones;

Features of the free version:
- Free tool without advertising
- Number of loads is limited to 10

The application is optimized for tablets and is able to be installed on the memory card.
