Microwave Nlos HD-Sdi Hidden Camera Video Transmitter High Definition Multimedia Interface For Covert Investigation
Wireless Microwave Nlos HD-Sdi / High Definition Multimedia Interface Hidden Camera Video Transmitter for Covert Investigation
Introduction:
Mini COFDM wireless radio transmitter is with the core of mobile communication technology COFDM (multi-carrier modulation technique). COFDM wireless transmitter can transmit high quality and stable full HD digital video signal under the condition of high speed mobile and heavy building non-visual transmission in city environment.
COFDM wireless transmitter supports full HD 1080P H.264 encoding format and High Definition Multimedia Interface/SDI, stereo balance audio input and narrowband transmission system.
Features:
- Power output: 100-400mW as default;
- Frequency: customized within range 300MHz to 2GHz. normally there is 40MHz that users could change by themselves. for instance, if the central frequency is 340MHz, then users could change it from 320MHz to 360MHz.
- Bandwidth: 1.5/2/4/6/7/8MHz adjustable
- Interface: High Definition Multimedia Interface and HD-SDI
- Video encoding: H.264
- Video quality: HD 1080P
- Video encryption: AES
- Receiving: diversity receiving technology which requires 2 antennas for each receiver, normally two omni antenna
- Distance: 100-400m in city environment, like covert investigation, and up to 15km in LOS environment, like UAV application
