Peter welcomes you to the Forum!
You will not be able to share the secrets of work: how do you monitor?
It all depends on the circumstances:
1. The identity of the object (is he familiar with the methods of observation and counter-observation)
2. Whether the technical means of transportation use the object or not.
3. Does the facility have security (security service)
In ordinary observation, a team of "stomp" is used; the number of people depends on the complexity of the facility and payment. When using equipment (vehicles), additional technical means of observation (GLONASS, GPS) are used, which, if possible, are attached to the equipment. If the needs of observation exceed the capabilities of the company (not enough manpower and means), "colleagues" are involved.
