As time went by, people not only wanted to secure the safety of their cherished possessions which includes vital information such as battle or work strategies, but also wanted to find out who was interested in stealing them, and possibly why.

Types of Surveillance Systems
Different types of surveillance systems have been employed over time and the devices being manufactured for surveillance only keep getting finer, cheaper, more portable, more available, and easier to conceal.
So, be of the best conduct wherever you are because you never can tell who is watching you and why.
Surveillance materials that have been used and of which some are still in active use include telephones, bugs, closed-circuit television, computers, photography, electronic trails, and biometric surveillance, among others.
Mode of use of some surveillance systems
Telephones: Because the government gives the contracts and licenses to the network service providers, they can obtain communications data from these companies. Data can also be made available to the police department to aid investigations.
Phones, especially cell phones, store data about the caller, duration and time, details of the call, and of course who was called. It is also possible to get a greater resolution of a person's location by combining information from a number of cells surrounding the person's location.
Closed-Circuit Television (CCTV):
This equipment with which a picture is viewed, recorded but not broadcast was initially developed to improve security in banks but today it has become simple and inexpensive enough to be used as home security systems, and for everyday surveillance.
