Allan wants to detect brute-force physical attacks. What should he do if he wants to detect the broadest range of physical attacks?

A monitored camera system will detect the broadest range of attacks. Guards will only detect brute-force attacks when they are in the area, and cameras can cover more spaces at once. Inspections may miss attacks where camera recordings and monitoring can show failed and successful attacks. An alarm system won't detect attacks by insiders, who may access spaces they have access to in order to perform malicious actions.
