The city of more than 30 million is hoping the cameras will help reduce crime.

"Chongqing police chief Wang Zhijun said the system would be the world's largest new security network since the September 11, 2001 attacks in the United States, the Global Times reported.

The system would dwarf a network of 40,000 security cameras installed in the capital of China's far-western Xinjiang region last year, following deadly July 2009 clashes between Muslim Uighurs and members of the majority Han group.

Chongqing's more than 500,000 cameras, which are due to be installed by 2012, will mainly be used for crime prevention, emergency controls and rescue operations, a police spokesman told the Global Times."
