Annotation: This document establishes performance requirements and test methods for miniature recording devices and systems used in undercover surveillance.
Abstract: This technical document specifies performance and other requirements that equipment should meet to satisfy the needs of criminal justice agencies for high quality service. A miniature recording system includes the recording device and its power supply, a separate microphone, and a playback unit. All parts of the miniature surveillance recording system are addressed by this standard excluding the microphone. This standard places requirements on the output from the playback unit only, since this characteristic is most critical to the effectiveness of the system. Miniature surveillance records (MSR) are classified by a system that allows a listener to identify who is speaking in addition to what is being said or a system that allows a listener to identify what is being said, but not necessarily who said it. All test procedures involve magnetic recording of a test tape using the recorder portion of the MSR system under test and playing back this recorded tape on the playback portion of the same system. 5 references, bibliography.
