The PKI 2145 Digital Needle Microphone Recorder records conversations through keyholes, wall bores and other openings of at least 3mm in Ø. This is possible because of the 2.5mm strong metal tube with attached special electret microphone. Direct listening-in via the delivered earphones is possible or the recorder automatically records for up to 14 hours. The microphone needle can be variably extended by 2 further attachable metal tubes. So, lengths of 5/ 15/ 20cm can be achieved. For the wall bores, we can recommend our PKI 8040 Silent Drill.
