Earlier this year a website, Security-Cameras-cctv.com, was issued a citation from the FCC for violation the Communications Act because wireless transmitters it was selling that weren't FCC compliant.
Here's what happened:
The FAA filed an FCC complaint because it was experiencing interference with one of its doppler weather radars in Las Vegas. The FCC investigated and traced the interference back to a storage facility 20 miles away in Henderson, Nevada. Investigators found a "5.8 GHz wireless video transmitter and observed that it contained neither an FCC identification number nor the name of a manufacturer."
They contacted the installer who said he bought it from Security-Cameras-cctv.com and provided them the invoice.
The FCC sent a citation to the online store telling them they couldn't sell the transmitters anymore. They had 30 days to respond. That was in January. The model named in the citation is no longer for sale online. The storage facility said they've since switched to an analog system.
When you're selling, receiving, buying equipment, especially wireless equipment, are you looking to make sure this stuff is FCC compliant? Should the installer have caught that?
