Beijing authorities have initiated a ban on all secret surveillance equipment in the city amid increasing pressure from the central government to crack down on spying activities.
The decision was issued jointly by the city's Administration for Industry and Commerce, Beijing Municipal Public Security Bureau and Beijing National Security Bureau, which added that purchases of these devices–such as surreptitious cameras installed in glasses or walking sticks to secretly record photos or videos of people in bathrooms and changing rooms–could lead to serious criminal liability...
