It’s noteworthy that Mong Kok are venues where pro-democracy demonstration take place.
According to Cable News, a fund was granted by the previous Yau-Tsim-Mong District Council to install 4k lens in the surveillance camera at the height of Sai Yeung Choi West Street by April this year.
Introduced 11 years ago following acid spilling incident in Mong Kok, the last District Council further expanded usage of surveillance footage from investigating falling objects from height to any criminal cases. The video footage will be kept for 30 days and police can apply to extract footage of up to six hours before and after an incident.
The Operational Guidelines of the Home Affairs Department state that the video is shot at a fixed angle and range and will not point to any apartment unit. They said facial recognition will not be applied.
