Professional Day and Night Audio/Video Directional System

Product number: PKI 2900

With the PKI 2900 Professional Day and Night Audio/Video Directional System it is finally possible, after years of PKI development, to record voice and video recordings at a distance. Which possibilities are now feasible with the PKI 2900 Professional Day and Night Audio/Video Directional System becomes clear to every user during operation. What previously remained hidden is now revealed with PKI 2900.

The outside box contains 7 microphones, as well as two cameras for each microphone. The microphones have an acoustic gain due to the horn effect and are brought to the audio standard level with the integrated special amplifiers. The amplifiers have special bandpasses, so that the PKI 2900 Professional Day and Night Audio/Video Directional System can be used especially well outdoors. All 7 sectors can be grouped together individually or several sectors, up to a 360 degree surveillance. There are 2 cameras per microphone, i.e. 14 cameras and 7 microphones. PKI 2900 is therefore ready for day or night use.

By switching on the respective IR-Laser per sector, the monitoring direction is particularly easy to control. The electronic multiplex control unit in the vehicle processes the 14 incoming video or 7 audio signals and transmits the desired data to the laptop supplied. Thus the received acoustic audio signal and the video signal recorded by the cameras can be made audible or visible. Simultaneous documentation recording is also possible.
