日本公司推AI攝像頭 用來識別小偷

Artificial intelligence (AI) continues to seep into our daily lives. Now, AI has been tasked with tackling a crime: shoplifting.

人工智能（AI）不斷滲透我們的日常生活。如今，AI又被用來應對一種犯罪：入店行竊。

NTT and tech company Earth Eyes have joined up to create AI Guardman.

日本電報電話公司，已經聯手科技公司Earth Eyes，打造出AI Guardman。

This is a new type of security camera that is backed up with an AI system that can detect behaviors attributed to shoplifters.

這是一種新型安全攝像頭，配有AI系統，可以檢測到疑似商店扒手的行爲。

The way it works is simple. The camera watches the store interior and identifies all the humans inside as they walk about.

該攝像頭的工作方式很簡單。它會監視着商店的內部，並在所有人走動時識別出裏面的所有人。

AI Guardman is aware of the different techniques commonly used by shoplifters in different types of stores, such as looking for blindspots in supermarkets or constantly checking one's surroundings in bookstores.

AI Guardman對扒手在不同種類的商店使用的不同慣用伎倆了熟於心。比如說扒手會在超市裏尋找盲點，或者在書店裏不停地查看周圍的環境。

Preliminary tests appear to be effective. Trials have been conducted by major retailers, and it is expected that the system will get stronger as it is used.

一些主流零售商試用了該系統，初步測試似乎效果顯著，預計該系統將在使用過程中變得更加強大。

The AI Guardman costs a fair amount. One camera, which has a range of 13 meters, costs $2,200 up front. Then, there's the $41 per camera monthly fee for usage of the cloud data it produces.

AI Guardman價格不菲，一個監視範圍爲13米的攝像頭的預購價高達2200美元。此外，每個攝像頭每月還需支付41美元的雲數據使用費。
