Adhoco uses the standard Zigbee (www.zigbee.org) as radio communication. This permits it to transfer reports coded. The Adhoco System works with the 128-Bit AES key procedure, which admittedly offers high security (as e.g. with the Internet Banking). Besides the individual devices announce itself with their global clear identification number with the control center adhoco.H1; and adhoco.H1 accepts only such participants for the transmission of information. Since the radiograms besides are very short and rare, an aggressor cannot crack the key also with large arithmetic performance.
