Zone of Silence is a small wireless device that gives premise owners the ability to control in-zone cell phone and PDA functionalities such as: inbound calls, outbound calls, inbound SMS, outbound SMS, vibrate only notification, maximum screen brightness, internet connection and camera functionality. This is done without the use of jamming.
The wireless ZoS signal strength ranges from ten to 300 feet and is adjustable to the size of the zone. Large venues can effortlessly chain multiple devices together to create a larger zone.
ZoS is designed with safety, security and flexibility in mind. ZoS does not block any cell phone frequencies but instead communicates directly with individual cell phones to limit functionality and even allows designated phones to be free of ZoS restrictions. ZoS can be remotely deactivated at any time and the zone owner may also select inbound phone numbers that are always to be allowed through.
With Zone of Silence, 911 is ALWAYS enabled for the safety of your zone.
