Introduction:
The
Knapsack Digital Wireless Video Transmitter adopts the latest technologies of
COFDM modulation and MPEG-2 image compression that enables good NLOS (Non
line-of -sight) transmission with DVD quality video. The transmitter is compact
size with power amplifier for longer-range transmission. This system 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.
Features:
■COFDM
modulation, Stable transmission
■MPEG-2 video compression, DVD video
quality
■Lithium battery for power supply
■Mobile and NLOS(Non
line-of-sight) transmission
■Great security by encryption of AES 128
bit/ALLTECH Basic Scrambling
■Low system latency
■Modular
design, compact structure, small cubage
■Several wavebands available: VHF/L/
S
■Strong casing with built-in cooling plates, waterproof and
shockproof
■In LOS (line-of-sight)environment, the transmission range is up
to 80km
Product
Application:
The Knapsack Digital Wireless Video Transmission system
is the ideal solution for first responders or military personnel entering
hazardous environments. The first responder can carry the equipment on the back
to enter accident ground and then the transmitter send the camera’s digital,
compressed signals to the commanding center.
