Product description:
Monitoring the first manual
Thank you for using this product, the product is as the adoption of hi-fi-chip low noise
Through several election-effective noise suppression and high-frequency sound interference, echo cancellation cavity effectively reduce the serious echo room open, to achieve a perfect radio
Pure tone, dynamic Weimeng, built-in automatic gain control (AGC) circuit designed from
Adaptation in the bank, Prison, the examination room, shopping malls, industrial production, and other places eavesdropping Shiyin, A small noise, high-fidelity, wide operating voltage range, power consumption small, transmission distance and other advantages
A new sensitivity to adjust the pickups, TV monitoring, security systems supporting the use of the best products, and with the use of cameras to achieve synchronous video and audio
