Chapter 13. Build a Security System > Intrusion Deterrence

13.3. Intrusion Deterrence

Of course, intrusion detection is only useful if your security system takes action in response to events. Typically, security systems kick off several different types of responses: intrusion deterrence, alerting, and recording evidence. This section covers intrusion deterrence mechanisms that will hopefully scare away the potential intruder.

Silent alarms are good for catching an intruder in the act, because they notify the authorities while making the intruder feel like they have successfully broken in without activating an alarm. I'm more interested in my own safety than getting a criminal off the streets, though, so I'd rather scare an intruder away than catch them. If you would prefer a silent alarm, you can skip this phase of the project.
