Alarms and sirens
An alarm is worth what it can grow into: being able to add a sensor or a siren later saves replacing the whole system. Wireless systems go in without building work, while wired ones suit a renovation better. Check how it behaves during a power or internet outage too. An outdoor siren deters mostly by being seen, far more than by how loud it is.
