The AVISO system consists of at least one transmitter and one receiver. The transmitters (battery-operated with a running time of 8 years) detect signals such as the ringing of the phone, the doorbell, the crying of the baby etc.
and convert them into optical signals and vibrations using the latest radio technology. The receivers (AVISO Bee Flash) are simply plugged into a socket and receive the radio signal. Thus, the ringing of the telephone or the door bell etc.
is visible in every room, in the basement or in the attic etc.
