Camera Mount COFDM video Transmitter

Product Detailed

COFDM modulation; MPEG-2 video compression; 1.25/2.5MHz, 6/7/8MHz bandwidth optional; frequency customized.

Introduction

This product is a new kind of broadband wireless video equipment that adopts the latest technologies of COFDM modulation and MPEG-2 video compression that can complete video transmission in high-speed motion and NLOS (non line-of-sight) conditions. The diversity receiving technology greatly improves the receiving quality in all conditions. This transmitter is specially designed to meet all necessary transmission requirements of broadcasting standard .It has been widely used in many fields such as: Police Forces, First Responders, Security Services, Fire Services, Port Security, Homeland Security, Traffic Management, Police Technical Support Units, Special Forces, Military Command and Control Posts, Airport, Border Control, Major Incident Support etc.

Application
