  3. Monitoring: An indoor alarm siren can be connected to a monitoring service, which can notify the authorities in the event of an intrusion or other security breach. This can help to ensure a quick response time and increase the chances of apprehending the intruder.
  4. Peace of Mind: Knowing that an indoor alarm siren is installed in the home can provide peace of mind for the occupants, as they can feel more secure and protected against potential security threats.
