According to TFA, which of course no one has bothered to read:
Shodan crawls the Internet at random looking for IP addresses with open ports. If an open port lacks authentication and streams a video feed, the script takes a snap and moves on. The cameras are vulnerable because they use the Real Time Streaming Protocol (RTSP, port 554) to share video but have no password authentication in place. The image feed is available to paid Shodan members at images.shodan.io. Free Shodan accounts can also search using the filter "port:554 has_screenshot:true."

That doesn't refute what the GP said - you still need to "be a member", even if an unpaid member.
(I also believe there's a limit to the number of search results returned.)
