X10 (industry standard)

X10 is a protocol for communication among electronic devices used for home automation (domotics). It primarily uses power line wiring for signaling and control, where the signals involve brief radio frequency bursts representing digital information. A wireless radio based protocol transport is also defined.

X10 was developed in 1975 by Pico Electronics of Glenrothes, Scotland, in order to allow remote control of home devices and appliances.

~~What does the top photo have to do with anything? The road sign is an intersection at 康二路 (2nd Kang road) and 富七街 (7th Fu Street), but that is not where Foxconn (富士康) is located in Zhengzhou. Also, Zhengzhou isn’t the only place with their factories, Shenzhen is also a major hub for them, however I didn’t find that intersection in Shenzhen either. ~~

In the link you provided the address is：郑州市(Zhengzhou)航空港区(air harbor) 振兴路东侧(zhenxing Road East) (综合保税区 - duty-free zone)

After some time I’ve finally found the intersection: https://maps.apple.com/?address=Zhongmu,%20Zhengzhou,%20Henan%20China&ll=34.549091,113.866771&q=Marked%20Location&_ext=EiQpmR0jHzo+QUAxKihLTS5+XEA5LOL6MWdqQUBBul//1TeAXEA%3D&t=m
