What is a cost-effective reason for using vehicles in stationary surveillance?

Using vehicles in stationary surveillance serves as a cost-effective reason because they act as a base of operations. A vehicle provides a discreet location where investigators can remain hidden from the subject under surveillance while maintaining a tactical vantage point. This allows for the collection of valuable information and observation without the need for extensive additional equipment or personal resources. Furthermore, a vehicle can be equipped with necessary surveillance tools, such as cameras and communication devices, streamlining the investigative process.

In contrast, while better communication signals could be an advantage of certain vehicles equipped with advanced technology, it is not the primary reason for using them in stationary surveillance. Similarly, visibility might be enhanced by a well-positioned vehicle, but this could also lead to detection if not properly concealed. Lastly, while vehicles may reduce the need for some equipment, they typically require maintenance and fuel, and thus their main advantage lies in providing a stable and secure operational base rather than necessarily reducing equipment needs.
