CANOBEAM DT-150 HD
Free Space Optics Wireless Transmission
The Canobeam DT-150 HD provides reliable uncompressed two-
way, high-bandwidth (HD-SDI and SD-SDI) digital video
transmission for situations where fiber-optic cables or microwave
links are impractical or impossible. The Canobeam DT-150 HD
operates at 1.5 Gbps and transmits digital HD/SD video, audio,
and control signals bi-directionally without delay via line-of-sight
Free Space Optics at a distance of up to 1 kilometer.
• The Canobeam DT-150 HD can relay HD-SDI and SD-SDI video,
along with embedded return video and audio to the camera
operator, as well as camera-control signals, and robotic
camera-control data.
• Canon's exclusive Auto Tracking feature—standard on all
Canobeam systems—maintains precise beam alignment
despite vibrations due to wind, heavy vehicle traffic, or
unsteady camera platforms.
• Small Form Pluggable fiber interface. (Connector: LC)
• Can interface with either simple media converters for
one-way/two-way video transmission or SMPTE hybrid cable
emulation boxes.
• Housing designed for outdoor or indoor installations.
• Offers management capability via SNMP.
• The Canobeam DT-150 HD's Free Space Optics technology uses
a beam of infrared light, which doesn't require RF licenses or
coordination, and is virtually free from interception.
• The Canobeam DT-150 HD's sets up quickly and is simple
to operate.
