Good tech

The Herald reports:

High-tech security cameras powered by artificial intelligence gadgets that detect active shooters are being installed at Christchurch’s Al Noor Masjid where 44 Muslim worshippers were gunned down in March.
The state-of-the-art surveillance system is designed to detect an active shooter and alert police and other emergency services before shots are even fired.
The New Zealand mosque is understood to be the first place of worship in the world to be protected by the technology.
It’s already been installed at several schools and public spaces in the United States. 
Shagaf Khan, president of the Muslim Association of Canterbury which runs Al Noor, welcomed the move to give his congregation extra safety measures.

“I wasn’t aware of this technology, it’s amazing,” he said.
“If somebody comes with a weapon, it will give a notification within three seconds to authorities and police.

That is indeed amazing technology, if it works as described.It could save lots of lives in future.
