Which statement about yard signs for alarm systems is true?

The statement that yard signs for alarm systems act as a deterrent to potential burglars is accurate because studies and surveys consistently show that visible security measures, like yard signs and stickers, can discourage criminal activity. When burglars see yard signs indicating that a property is protected by an alarm system, they are more likely to think twice before attempting a break-in, as the perceived risk of being caught increases. This psychological effect is part of a broader strategy for crime prevention, where visibility and awareness play crucial roles.

While the other options may contain elements of truth, they do not convey the primary purpose and effectiveness of yard signs as effectively. For example, the effectiveness of yard signs does not necessarily increase at night since visibility can be reduced in low light conditions, and their placement is not legally restricted to front yards alone. Additionally, there are no legal mandates requiring the display of yard signs in relation to alarm systems, making their use primarily a tactical choice rather than a legal obligation.
