Key Specifications
Why COFDM digital transmission system?

Coded Orthogonal Frequency Division Multiplexing

1. Requires much narrower bandwidth than analog’s

2. Resistant to multi-path

3. Robust signal in NLOS (non line of sight)Performing inside buildings, through walls, and around corners

4. Error correction & strong encryption

5. High performances on aircraft, vehicles, ships

6. Performs well in high speed moving transmission

Introduction of COFDM video receiver radio modem 485 hd sdi mobile dvr for surveillance robot

SG-HC01 is a new design COFDM wireless video audio receiver from Safe Guard. It’s designed with built-in PTZ controller, which is special for transmitting from end camera movement controlling. Build in 120G SSD memory and 17 inch highlight LCD screen, it’s allowed real time video image storage, video monitoring. It also support video playback.

The convenient portable pelican case, PTZ controller, and large volume internal battery design make it wildly applied in outdoor tactical automatic project, like surveillance robot/ship, EOD robot, UAV point to point application etc.
