The Federal Communications Commission has blocked two devices from sale in the US, according to The Verge and an FCC release. The FCC said they have chips made by a Huawei unit.

The FCC's release, posted by Light Reading, said the devices are a dashcam and a wireless video sender. The Verge said the agency did not name the brands.

The FCC called the part a "surveillance chip," The Verge and the FCC release said. The Verge said it is a chip that turns a camera sensor into a device like a home security camera or a dashcam.

The chip maker says it is "designed for the surveillance market" and can spot human faces, the FCC said in its release, which The Verge also cited.

Huawei is on the FCC's Covered List of firms seen as security threats, The Verge reported. New rules that took effect last week bar devices with "smart" parts made by firms on that list, the FCC release said.

This is the first time the FCC has used that power, The Verge and the FCC release said. The Verge said the rule closes a gap that let parts from banned firms end up inside other products.

"Video devices containing surveillance chips produced by Covered List entities pose an obvious and unacceptable risk to the nation and our people," FCC Chairman Brendan Carr said in the release. He said the agency would keep acting "aggressively" on its rules.

The Verge questioned whether the FCC is keeping people safer or "picking winners and losers while making a show of enforcement." It said the agency has not responded to its requests to discuss its efforts.

What we know: The FCC has blocked two devices with chips from a Huawei subsidiary.
What we don't: Which brands made the devices, and how many more products could be blocked.
