Professional Grade, Single zone audio surveillance system for use where sound quality and recording of conversations is of critical importance. Kit includes professional grade Cardioid pattern microphone and DVR-I/P camera interface featuring 48Vdc phantom power supply, ultra low noise microphone preamplifier, 7 band equalizer and compressor/limiter (automatic level control). Equalizer provides +/-12db sound emphasis or de-emphasis in 7 ranges of frequencies (60hz-15khz) for tuning out background noise and emphasizing the desired sound qualities in acoustically difficult environments such as interrogation / interview rooms. Compressor / limiter Automatically lowers the gain in loud environments and when quiet, raises the gain where faint audio sources such as people whispering can then be heard.
