Surveillance cameras are pretty much a standard when living in many cities. And many of those cameras are connected to the internet, and may be deliberately or inadvertently open for others to tune into. Exposed devices can be everywhere, from businesses, to schools, to inside homes. A new tool allows you to see where insecure cameras are physically located.

Whereas some researchers would ordinarily have to crawl through lists of open devices on the computer search engine Shodan, this new tool lets users enter an address to find nearby ones on a map.
