The ParMarLow Wireless Interview System allows for prompting the Interviewer without interrupting the interview. Now the line of questioning can be directed without alerting the suspect / victim that something they said was of interest. Low Power, QPSK Signal Modulation, 600’ LOS (Line of Site) Insures low intercept potential, in house or at a remote location. Used with the ParMarLow WR-RX06 Wireless Earpiece, the suspect / victim is unaware that the interviewer is receiving information from the investigative team. This is extremely valuable when interviewing children and young adults who are very aware of their surroundings.
