What is one common security technology used by guards?

CCTV systems are widely used in the security industry due to their effectiveness in monitoring and recording activities in various environments, such as businesses, public areas, and private properties. They provide real-time surveillance and the ability to review footage for any incidents that may occur, enhancing overall safety and security measures. This technology enables security personnel to observe multiple areas simultaneously and can act as a deterrent to potential criminal activity, as the presence of cameras is often enough to discourage wrongdoing.

While other security technologies like metal detectors, two-way radios, and infrared sensors also play important roles in security operations, CCTV systems stand out due to their ability to capture and store visual evidence, which can be crucial in investigations and legal proceedings. This capability makes them particularly valuable in a range of security settings.
