COMMON QUESTION: What is the farthest distance that can be recorded?ANSWER: There are a lot of variables involved in answering this question, such as, how loud the audio is, background noise (wind, radio, road noise, machinery, air conditioning etc.), indoor or outdoors etc. We have successfully recorded clear audio from over 50 feet away while talking normally in a line of sight quiet warehouse setting. Actual distance could be more or less depending on the circumstances.
