NLOS transmission Lightweight HD UAV COFDM Video Transmitter 20km Long Range Distance
Introduction:
It has character of super light weight and mall size,use MPEG2 coding format and COFDM (coded orthogonal frequency division multiplexing) digital modulation, provide high quality image in revolution 720*576.Support NLOS transmission and reception as well high speed mobile transmission.Can be carried in your pocket / briefcase for secrect evidence. it can send live video of the scene circumstances to the rear command post. Widely used in UAV,public security organs, procuratorate, court and security bureau etc.
Features:
- Transmitter only has 195g net weight(without battery),very easy for portable and UAV applications.
- COFDM modulation, Stable transmission
- MPEG-2 video compression, DVD video quality;
- Modular design and highly integrated
- NTSC/PAL automatically adapt ,support user adjustable;
- Shortly time delay;
- Lithium battery for power supply(continuous working time is 3 hours max)
- Supports high-speed mobile NLOS ( Non Light Of Sight ) transmission;
- Adjustable working frequency,bandwidth,RF power and etc.
- Transmission security by encryption of AES 265 bit.
- Good quality image without any mosaic;
- Matched with multifunction amplifier for longer range requirement.
