They are Surveillence agent. If you look closely, you will see.
LVL 3 agent can track people outside the region you are in.
They are not Surveillence agents, they are spread out all over. The list of good location agents I made for the region I am currently in include the following divisions:

Higher level/quality agents can often search futher away and complete the search faster but require higher standing with the corp to use and cost more isk.
