The A1R-KIT radio transceiving system is a very particular device because of its double function of a sensitive RF covert transmitter and a long-life micro digital voice recorder. Both features are integrated into a unique wireless module manageable from over 400m away. The A1 module is also known to provide a high recording quality and a wide customizable choice of settings (voice activated system VAS, operating timer, encrypted hardware key and so on), as reported by its functional features.
Thanks to a high quality sound from 8bit@8kHz to 16bit@44kHz and the ADPCM compression suitable for the encryption of audio recordings, the A1R-KIT can be quietly counted among the most rugged, safe and effective devices in the intelligence field. The full system is known as well to have a high level of safety against the most radio frequency detectors.
However the A1R-KIT has many other advantages. The receiver, for example, has a big LCD display and intuitive interface to control the whole A1 system. The recordings stored in the microSD card can be fast downloaded directly from the receiver, avoiding the physical access to the recording module.
When connected to a direct power supply*, the A1 becomes the ideal assistant for your long or very long audio monitoring sessions, placed in hard locations.
