Campus security services play a critical role in maintaining safe learning environments at both K-12 schools and higher education institutions. School Resource Officers (SROs) serve as vital partners in this effort, providing a visible security presence, building trust with students, and responding swiftly to incidents while respecting the delicate balance between safety and the privacy rights of minors. On larger, open campuses, protecting students and staff requires a blend of traditional tactics and modern tools, including surveillance systems, access control technology, real-time communication networks, and emergency alert systems. Security strategies must be tailored to each campus's unique layout and culture, ensuring that while campuses remain open and welcoming, they are also prepared to prevent and respond to potential threats effectively.
