CommDirect radios and surveillance mics for staff and security - they utilize the MOTOTRBO XPR 7500 series radios that let you:
o Listen to multiple channels at once
o Do an all-call
o Scroll through all channels rather than have to go through zones
o Little to no digital delay even with a repeater
CommDirect can also provide it turnkey and bring out their repeater(s), staff, and set up an office to provide everyone with radios. They also will scan them in/out to account for them like you currently do.
