Final answer:
Oscar's installation of a burglar alarm and CCTV cameras as a precaution against burglary exemplifies situational crime prevention, a strategy aimed at reducing opportunities for crime.
Step-by-step explanation:
Oscar's actions of installing a burglar alarm and CCTV cameras are an example of situational crime prevention. This term refers to strategies that aim to reduce the opportunity for crime to occur by increasing the difficulty or risk of committing the crime, or by reducing the rewards. In contrast to Social Disorganization Theory, which discusses crime in relation to a community's social fabric and its abilities to maintain social control, situational crime prevention focuses on specific measures that deter criminal behavior.
