What type of device would typically be included in a basic security setup in a residence?

The inclusion of a motion sensor in a basic security setup for a residence is crucial because it provides real-time detection capabilities. Motion sensors are designed to detect movement within a certain area and can trigger alarms or notifications if an intruder is present, thereby enhancing the overall security of the home. They can be integrated into security systems to activate when there is unexpected movement, providing peace of mind to homeowners.

While security cameras are useful for surveillance, they are primarily a reactive measure and do not provide the immediate alerts a motion sensor does. Window locks contribute to physical security but do not offer any detection capabilities. Security personnel typically represent a significant investment and are not commonly part of the basic security setups for residences, making them impractical for many homeowners seeking straightforward solutions for protection. Therefore, in the context of a basic security system, a motion sensor stands out as a proactive measure that effectively aids in deterrence and response to potential intrusions.
