What are "Other Applications"?

Question

Hi folks, 
 while investigating an issue with my security cameras I came across this classification in current connections. When reviewing the Application classification list there is NO "Other Applications", so how do I determine what application is being used? 
 I also saw the same on other devices in the connection list.

I finally stumbled onto your answer in the manual. Basically "Other Applications" isn't an aggregation of small, misc Applications, it means that there is no Application identification. So literally, the application being used is "I don't know". 
 If you click on the number to the far right, it takes you to the log row(s) associated with the traffic so you can look at source and destination ports, Rule ID, etc, to attempt a manual classification. From the manual page:

Application 
 Shows the names of applications currently connected. Other applications lists unrecognized applications along with the rule ID of the applied firewall rule. It also lists system-generated traffic between Sophos Firewall and any zone. The rule ID is set to zero because firewall rules don't apply to system-generated traffic.
