When someone tries to break into your home you want them to know they need to get out of your stuff. What better way to let the bad guys know they have been busted then with loud noises and flashing lights to draw the attention of your neighbors and those passing by.

Sirens come in indoor and outdoor models. Indoor sirens typically make noise in the 80-100 decibel range. Outdoor models sound in the range of 100-110 decibels depending on the model. High quality outdoor models are tamper resistant to prevent a criminal from disabling it before making their entry.

Outdoor sirens can also have a strobe light built into them to draw attention to where the alarm sound is coming from making it easier for help to find where they need to be going.
