An inside siren is one that simulates a doorbell and placed high on a hallway wall, or a large siren is often placed in your return air vent. This will let a burglar know that they have violated an alarm so that they will hi- tail it out of there. It will also let you know that your system has been violated so that you can release the hounds, load your gun or hide under the covers, whatever you select as an appropriate response.
(HOT TIP!) Sirens are measured in decibels and wattage. A large siren would be 30 watts or more and at least 100 decibels. If you settle for a non- descriptive commitment such as "It will be loud" you may have authorized a smaller and less expensive siren to be installed. They are all loud, but the louder the better when it comes to scaring a burglar away.
