Precisely determining the device type from an open media port may produce inaccurate inventory. Use the port number as a starting clue and look for independent evidence.

Basic approach

RTSP is a protocol used to control media sessions. Servers other than the camera can also provide RTSP service; Cameras may use non-standard ports. The accessibility of the port does not indicate the existence of the flow or that the authentication will be successful.

Application steps

  1. Register the open port with the transport protocol used.
  2. Compare individual sources such as ONVIF, device management panel, and manufacturer information.
  3. If identity is uncertain, use possible media device or unknown status instead of automatic camera tag.

Practical example

Media software running on a computer can provide RTSP service. Counting this computer as a camera just by looking at the port number will inflate the actual number of cameras on the network and mislead the maintenance list.

Interpret the result correctly

Stream URLs may contain a username or password. Mask them in the support report. Even on a device to which you are authorized, constantly streaming can consume bandwidth; Gather the minimum information needed for exploration and log off.
