For the purposes of managing, influencing, guiding, or safeguarding, surveillance is the close observation of a person, a group of people, behaviors, activities, infrastructure, buildings, etc. There are numerous techniques for surveillance as well. GPS tracking, video surveillance, and stake-outs are some of the techniques. Data mining, profiling, and biometric surveillance are other options.
The stationary nature of the camera often places restrictions on traditional observational monitoring techniques. Therefore, the camera is typically operated manually or mounted to a tripod or other support. Although using a helicopter for aerial surveillance results in the intended outcome, it is also quite expensive.
