What is an effective, inexpensive alternative to expensive security systems mentioned in the text?

Everyday objects serve as an effective and inexpensive alternative to costly security systems because they leverage items that are already present in people's daily lives. For instance, objects such as furniture, bicycles, or even decorative elements can be rearranged or employed strategically to create barriers and improve home security. By using familiar items creatively, individuals can enhance their safety without the financial burden of investing in advanced technology or professional services. This approach not only minimizes costs but also encourages individuals to think critically about their environment and find practical solutions using resources already at their disposal.

In contrast, physical barriers require specific installations and maintenance, which can add to expenses. Professional security services typically involve ongoing costs and contractual obligations, making them less accessible for everyone. Although smart home devices offer modern features, they often involve considerable upfront investments, both in terms of the devices themselves and any necessary infrastructure, which may not be feasible for everyone. Therefore, utilizing everyday objects presents a unique blend of effectiveness and affordability for enhancing security.
