What feature is generally not found in basic alarm systems?

In basic alarm systems, smartphone notifications are generally not a standard feature. Basic alarm systems are designed primarily to provide essential security functionality, which typically includes sensing intrusion through motion detectors or door/window contacts and alerting homeowners through sound alarms when a breach is detected. While remote controls with keypads may be included for ease of operation, smartphone notifications require internet connectivity and integration with mobile applications, which are features typically found in more advanced or smart alarm systems.

As such, basic systems focus on fundamental alert mechanisms and do not typically incorporate modern technology that allows for remote monitoring and notifications via smartphones. This distinction clarifies why smartphone notifications are not part of the essential functionality offered by basic alarm systems.
