In physical surveillance, speech intelligibility is crucial. Every message must be clearly understood by all team members in every situation during a surveillance, regardless of the volume of the environment. The PKI 2660 Digital Wireless Covert System is designed to be particularly user-friendly and does not require any technical knowledge. PKI 2660 is completely immune to electromagnetic interference and does not interfere with other systems. The AES-128-bit encryption of the transmission guarantees a secure connection. The PKI 2660 Digital Wireless Covert System „in-ear receiver“ is almost invisible, it fits very discretely in your ear canal thanks to its ingenious miniature design. Long wearing times are possible without any problems due to the ergonomic design, a pleasant wearing comfort is guaranteed. The connection in addition to a radio or mobile phone increases absolute flexibility.
