New infrared surveillance cameras deployed at the foot of China's tallest skyscraper peer into the darkness, ever vigilant against infiltrators.
Concealed alarms warn the guardians of the Jin Mao Tower in Shanghai of intruders, and spikes prevent anyone from climbing the structure.
These state-of-the-art sentinels have been positioned around the tower to prevent not terrorists, but would-be Spidermen, from getting too close.
Climbers of man-made mountains, would-be Romeos, and those seeking 15 minutes of fame have all been drawn to the tower - located in the Pudong district of Shanghai. But so far only one has reached the 'peak'.
'Three people attempted to climb the Jin Mao Tower last year and one made it to the top' of the 88-storey building, said Gao Tianjie, vice-president of the China Jin Mao Group Co Ltd.
Han Qizhi, from Anhui province, reached the top of the skyscraper early last year.
'After that, Han became famous, and was hailed as China's first Spiderman,' said Mr Gao. Public reaction led others to attempt to emulate Mr Han's achievement. Despite increased patrols around the tower, a Shanghai resident breached security and tried to scale the Jin Mao after a quarrel with his girlfriend, said Mr Gao.
