reason that officers stay put at a given location while observing. The second method is called the two-person method. The same concept applies, with an officer observing a specific area, however an additional officer is added to the situation in an attempt to be more effective on the job. The second officer can observe in a different direction, creating a larger range for observation, while also providing a fresh set of eyes. The two-person method is both more effective and more efficient when it comes to Fixed Surveillance. Stationary Technical Surveillance is also a type of surveillance used by many police departments. This method is similar to that of Fixed Surveillance, however it replaces the officers with cameras and other technology.
