We prefer Zello for work with Bluetooth mics for encrypted digital communications while out patrolling, but we use CB SSB (Single Side Band) radios for backup communications when there is no cell service. 40 CB channels with upper and lower sidebands is 120 channels that nobody uses anymore. Wide open airwaves and free. #security #securityforces #securitypatrol #securitycompany #CVPI
