safety alarm system

Some are made to be placed along with the locking mechanism of a door. There are also those that are made to fit windows. Other times, they are
designed to detect the sound of breaking glass before they sound the alarm. Motion sensors are also effective as alarms. It could be a motion sensor light that would scare away possible intruders or motion sensor alarms that can be placed in balconies or other vulnerable entry points. Lock
systems can also be installed in different parts of the household.
