What type of communication equipment do security guards typically use?

Security guards typically use radios or mobile phones for communication because these devices allow for immediate and efficient communication in various situations. Radios, particularly two-way radios, enable security personnel to quickly relay information, request assistance, and coordinate responses in real-time, which is crucial for maintaining safety and situational awareness in their environment. Mobile phones provide added benefits, such as the ability to communicate over long distances, access emergency services, and utilize apps for enhanced security management.

While other options, like television monitors, can be useful for surveillance purposes, they do not facilitate direct communication between security personnel. Pagers and beepers, though they were popular in the past, are largely outdated in contemporary security operations where more effective communication methods are preferred. Landline telephones are limited in mobility, making them less practical in dynamic situations where security guards need to be on the move. Hence, radios and mobile phones are the most effective tools for communication among security guards.
