The audio module will give the camera security and surveillance system a new dimension - SOUND.

The built-in high-quality electric microphone with compression amplifier with an extremely wide range of sensitivity control and noise filter (ACOUSTIC ZOOM) allows you to capture the sound of the compressor and the ticking of the wall clock. By pinching the short-circuit clutch in front of the module, it is possible to optimize the noise properties for voice operated recording (VOR) recording systems.

Sufficient voltage to short-circuit the defiant output with an output impedance of 600 ohm makes it easy (by engaging the resistance in parallel to the input of the recording device or module output) to adjust the output voltage of the audiomodule to the line and micro-phone input levels of the recording device or monitor. The design of the module and connection via the terminal block to the ordinary multicore shielded conductor makes it easy to use in new and older camera systems. The module can also be used separately for acoustic surveillance. Small dimensions allow for hidden installation.
