Introduction:
By using COFDM Modulation technology, we independently researched & developed Wireless HD Mobile Transmission Relay equipment which can transmit A/V signals collected by on-site camera via wireless radio. Transmitter comes with anti-jamming cavity filter that can eliminate interference & jamming by other wireless equipment. It adopts AES/ABS (128bit) encryption to enhance information security.
Application Ranges:
Police, Fire Control, Traffic Police, Civil Defense, Urban Management, Environmental Monitoring, Flood Control, Electrical Repairs, Marine Law Enforcement, Customs & Border Protection, Port Monitoring, Forest Fire Control, Military Surveillance, Television & other related fields. High-resolution image can be mobile transferred in complex environment
.
Application Modes:
Backpack--Car; Car-- Commanding Center: Car - Relay - Commanding Center
