AxiomV Security Systems

My new experience with RBH AxiomV Security System.


AxiomV combines access control, building management, and security monitoring in a highly integrated and expandable system. AxiomV runs on a standard IBM compatible PC using Windows 2000, XP, or 2003 Server and is designed for use in installations ranging from simple two door systems to complex systems covering multiple sites and containing thousands of card readers and tens of thousands of card holders.


TDA 2822 headphone amplifier


Microphone Amplifier Module

This circuit based on a very simple single transistor amplifier which can use with any power amplifier. very low noise, 45dB stage gain. Input impedance: 2700 Ohm.
