SZ DJI Technology Co, the world’s largest civilian drone maker, announced last month it was giving 100 drones to more than 40 local governments in 22 states to help monitor public health issues associated with the novel coronavirus outbreak. Several federal agencies have expressed concerns that the devices could be used for spying in the United States, though the company denies that.
"Although federal law enforcement agencies have warned of potential information security concerns with DJI drones, it is not clear whether state and local law enforcement agencies are fully aware of these issues," the lawmakers said in the letter.
