Security Radio model X555 is a micro sized UHF walkie talkie used by surveillance teams, security teams, commercial users, and anyone who needs to communicate in city areas. UHF Radio signals are good at penetrating walls inside an office building, hotel, or warehouse, and these UHF Radios transmit strong, high frequency signals that can permeate the structure while retaining a stable, 2 way communication pattern. Used for urban communication scenarios, these compact UHF Radios are essential to security teams and security details.
 
In addition to each security radio, a discreet ear phone with a push to talk microphone is available for inconspicuous one-way and two-way communication. These listening devices come in wireless and hard wired configurations. 
 

How does the X555 differ from the X666? The only difference is the style or design. They are practically the same. 
 
Features:

• CTCSS  / DCS :     helps block out other people that use the same co-channels that you communicate on - a privacy feature for keeping radio users not within your 'radio group' out . . . also called Continuous Tone Coded Squelch System / Digital Coded Squelch
• Low battery alert: lets you know when you are running low with operating power
• Time out timer: used to limit the transmission talk time of a radio user
• Compact and sturdy design
