What may be a result of installing an alarm system without expert guidance?

Installing an alarm system without expert guidance can lead to a misunderstanding of the system's capabilities. Alarm systems are complex, with various features and functions designed to meet specific security needs. Without the necessary expertise, a person might not fully grasp how to operate the system effectively or might overlook critical aspects, such as proper placement of sensors, understanding warning signals, and utilizing all available features. This lack of understanding can leave vulnerabilities in the security setup and may ultimately render the alarm system less effective than intended.

The other options present potential misconceptions about what might occur without proper guidance. Increased familiarity with technology is unlikely to be the outcome of a poorly implemented alarm system, as improper installation can cause frustration rather than skill enhancement. A reduction in the number of alarms is not a direct consequence of lack of guidance; rather, it refers to how many devices are installed, which can be mismanaged due to incorrect assumptions about needs. Finally, better security for the property would not typically result from an installation lacking expert oversight; rather, effective security often relies on careful planning and understanding of the system's strengths and weaknesses.
