In­ter­net of Things keeps us safe

Shanghai Daily - - METRO - Chen Huizhi

THERE are more than half a mil­lion pub­lic In­ter­net of Things sen­sors in the city — in the streets, res­i­den­tial com­mu­ni­ties and high rise build­ings.

Now, a po­lice data cen­ter cu­rates all data col­lected by smart de­vices serv­ing pub­lic safety. The data cen­ter hosts 17.9 petabytes — a petabyte is roughly a mil­lion megabytes — on 5,000 servers. The data is pro­cessed through 181 apps and 400 com­puter mod­els.

As the city be­comes smarter, ac­cord­ing to the po­lice, it also be­comes safer. Smart bor­der con­trol sys­tems at 123 in­ter­change points be­tween Shang­hai and neigh­bor­ing prov­inces are said to be four times more ef­fi­cient than pre­vi­ously and have iden­ti­fied 194 fugi­tives and about 13,400 il­le­gal ob­jects since Septem­ber last year.

In 1,712 res­i­den­tial com­plexes where smart sen­sors and sur­veil­lance cam­eras are in place, not a sin­gle re­port has been made to po­lice since they were in­stalled. In over 3,500 high rise build­ings where sen­sors are in­stalled to de­tect fire, no fires have been re­ported.

The Er­lian Xinyuan res­i­den­tial com­plex in Qingpu District was among the first to get smart. Res­i­dents now scan their faces to get in and out of their build­ing or the com­plex, and the gate au­to­mat­i­cally in­forms po­lice if a chip-em­bed­ded e-bike is sneaked out of the com­plex with­out a match­ing chip-key.

In­side the com­plex, all fire hy­drants have wa­ter pres­sure sen­sors. Smart sur­veil­lance cam­eras look up at build­ings 24/7 watch­ing out for fall­ing ob­jects. Res­i­dents who throw things over the bal­cony are warned im­me­di­ately.

A man sur­named Wang, whose rel­a­tives live in this com­plex, told Shang­hai Daily that he’s im­pressed with the smart de­vices here and hope the one in which he lives will have them soon.

“When they in­stalled the smoke sen­sor at the e-bike park­ing lot here, they had a drill, and the sen­sor re­acted very quickly,” he said. “Also the face scan en­trance makes one feel very safe, and since I don’t live here, I have to reg­is­ter my­self with the guards at the gate ev­ery time.”

Po­lice said they will ac­cel­er­ate the in­stal­la­tion of smart de­vices for safety in the city, and in­te­grate their data base with Shang­hai Big Data Cen­ter, but data safety and pri­vacy will be en­sured.

Po­lice re­vealed the progress dur­ing an in­spec­tion by the city’s leg­is­la­tors yes­ter­day.

The leg­is­la­tors ex­pressed their ex­pec­ta­tion that a sus­tain­able model of fi­nanc­ing will be es­tab­lished to sup­port the in­stal­la­tion of smart de­vices for pub­lic safety.

Lu Yaodong, di­rec­tion of the com­mand head­quar­ters of Shang­hai Pub­lic Se­cu­rity Bu­reau, said cur­rently the gov­ern­ment, com­pa­nies and res­i­dents are in­volved.
