Certain smartwatches, particularly the kinds marketed to children, have been banned by German regulators because they are in violation of Germany’s surveillance restrictions.

Although the ban doesn’t identify specific brands, the Bundesnetzagentur, or Federal Network Agency, which regulates telecommunications, power and other networks in that country, said in a statement that the smartwatches outfitted with an app that allows parents to “surveil” their children, allowing them to "listen unnoticed to a child's environment" were thought to be unauthorized transmitting systems.

According to the agency, parents are using the devices to monitor teachers while the students are in the classroom and they warn school officials to be on the lookout for the devices. The agency also warned that known buyers of the product will be told to destroy the watches.
