The highlight of the PKI digital recorder development is our PKI 2165 Digital Data Transmission Recorder. Once installed, the records can be wirelessly called on the delivered laptop using our transmitter/receiver system operating in the GHz range and can be evaluated or processed there. In case of mains supply, audio surveillance lasting for months is thus possible. Depending on the requirements, you get the information you need without ever having to enter the room again where the PKI 2165 Digital Data Transmission Recorder is installed.
