This pattern is commonly associated with IoT botnets and opportunistic scanners targeting exposed RTSP services rather than passive measurement traffic.

Client sends RTSP OPTIONS requests to check supported methods and confirm that an RTSP service is exposed, then disconnects without attempting authentication or stream setup. This pattern is typically associated with automated reconnaissance or internet-wide scanning rather than active stream access.
