BEIJING (AFP) - Chinese authorities are to install CCTV surveillance equipment systems on more than 1,400 buses in Beijing, state media reported Saturday.

In the latest security move in the Olympic host city, the buses will be equipped so that the driver can press an alarm button in case of an emergency, the state-run Beijing Youth Daily reported.

The security gear also includes four cameras on each bus, the report said.

Such equipment has already been set up at 25 Olympic bus stops, according to the newspaper.

The security measures are the latest in a series implemented by Chinese authorities, including checks on the subway in Beijing and restrictions on entry visas, as they have warned of a wide range of threats to the Olympics.
