With its integrated microphone, the digital recorder records conversations up to a distance of 10m. As a result of its compact dimensions, monitoring operations can be easily handled. The playback quality of the PKI 2105 Digital Miniature Recorder always amazes, especially as the transmission rate is 256kbps. Contrary to wireless monitoring operations, the PKI 2105 Digital Miniature Recorder is not traceable. A double-faced adhesive film allows for a simple and fast installation. With the delivered earphones, a direct playback without PC is possible. For larger rooms, it is recommended to use several recorders so that no information gets lost.
