You usually only hear about spy cameras being used in the movies. However, in the real world they are used for good and bad purposes. When they are used for security they can help catch criminals. There are people who will use spy cameras for their own selfish and bad reasons that are illegal. Let me explain what I mean.
There have been many options available through the times for protecting society from people who are breaking the law. However, with the proliferation of computers, complex political and social systems and industrialization there is a greater need for a heightened level of security. The police and military will continue to protect us from the criminals and terrorists of the world.
However, there are also individuals that use other security services and private investigators to conduct their own investigations and to protect their families, properties and businesses. They use modern surveillance to help them protect what they feel strongly about. You will continue to see more and more houses that are equipped with spy cameras so that the families that live there can continue to be safe and to warn them of suspicious individuals.
