The Cat5 Intercom system was discontinued in the United States in 2017 due to privacy concerns, but it is back in service in Australia.
The Cat5 system uses radio technology to allow a person or group of people to communicate with a person in another location.
The system uses the Cat5 receiver, which is mounted on the wall behind a person, to transmit a signal that the person in that location can hear.
When the person uses the intercom, the system sends a signal back to the owner or owner’s partner, who in turn sends a message back to a phone or computer, and so on.
The Australian government launched the Cat 5 Intercom in 2014 and is still using the system to send messages back and forth.
This was not the first time the system had been discontinued, however.
In the late 1980s, the US Department of Defense discontinued the Cat 4 system, as well.
According to the company’s website, the Cat4 system was “designed for emergency and tactical communication situations and provides high quality intercom service to both emergency and non-emergency personnel.”
