F-4HD-TVI-TX/RX 4 HD-TVI /CVBS over fiber Transmitter/receiver kit - 20Km over single mode fiber / 2000 feet of the multimode fiber
F-4HD-1D-TVI-TX/RX: 4 HD-TVI /CVBSover fiber in one direction from the TX to RX, with reversed RS485 from RX to TX. for 20KM
These units are used to send 4 video signals and allow control of the video source device from the receiving location via RS485 data
While many current video deployments are using newer digital transmission systems; legacy analog systems are still relevant and less expensive than their more current counterparts. Thor Fiber now has a full line of less expensive, commercial grade Video Over Fiber systems in easy to use kits. Electronic and optical adjustments are never required with these automated plug and play units. LED indicators are provided for instant monitoring of the system status. Devices are available for either standalone or rack-mount installation, which is suitable for different working environments. Compatible with AHD-H, AHD-M, AHD-L / HD-TVI 720P & 1080P / HD-CVI 720P & 1080P. The optical module and core circuit are high-quality commercial level components that have unparalleled stability, and all optical & electrical interfaces match or exceed international standards.
HD-TVI stands for High Definition Transport Video Interface. It is a digital signal processing and transport technology for video used in HD security cameras and DVRs. The TVI standard is a digital signal modulated on the analog baseband video. Our device converts this signal to modulated light so it could be extended over the long distance over the fiber, overcome coax copper limitations
HD-TVI cameras currently support 1080p video resolution using the same coaxial cabling techniques used by traditional analog CCTV cameras. This makes it easy for people with existing analog CCTV systems to upgrade to an HD system because most of the time they can leverage their existing cable infrastructure.
