2. Noise Problem
-
Check if MIC4DVR is connected to audio input device without a pre-amplifier.
MIC4DVR has a limitation of max. audio output. If it is directly connected to device like
earphone, there may be a limitation of audio output or the specific sound “boo~”. In this case,
user may not hear the surrounding sound. Connect MIC4DVR to only audio input devices with
pre-amplifier.
-
Check the noise from surrounding devise.
Since MIC4DVR is hypersensitive to sound, it amplifies back-ground noise as well as audio
signal. When installing MIC4DVR, keep distance from devices making noise.
