Doors in quiet suburban neighborhoods are often left unlocked, as the perceived thresholds for theft are very high. Because of evolution on both sides and the social aspect of theft, the threshold for theft is very dynamic and heavily dependent on the environment. Methods of theft evolve to decrease the difficulty of theft, increased by newer anti-theft systems. For example, keeping money in an inside shirt pocket increases the difficulty of theft above that necessary if the pocket was on a backpack, since unauthorized access is made sufficiently more difficult. The kind of system implemented often depends on the acceptable threshold for theft. Insurance companies will often mandate a minimum type of anti-theft system as part of the conditions for insurance.Īnti-theft systems are designed to raise the difficulty of theft to an infeasible (but not necessarily impossible) level.
Expensive items will generally be secured with a higher cost anti-theft system, while low-cost items will generally be secured at a lower cost. This cost estimation usually determines the maximum cost of the anti-theft system and the need to secure it. In addition to the initial obtainable cost of an item, the cost of replacement or recovery from theft of the item is usually considered when considering the cost of installing an anti-theft system.

Motive and opportunity are two enabling factors for theft.
When clear owner identification is not possible, and when there is a lack of social observance, people may be inclined to take possession of items to their own benefit at the expense of the original owner. The best anti-theft device ownership-marking, e.g. Under normal circumstances, theft is prevented simply through the application, and social acceptance, of property law.
