4-Channel HDTVI Video and Data Over Multimode Fiber
The HDTVITR4A03 combines four channels of HD-TVI video with one channel of bi-directional data transmission over a single multimode optical fiber. It provides a practical way to connect multiple HDTVI cameras to remote monitoring, recording, or control equipment.
A typical installation places the transmitter at the camera end of the link and the receiver at the monitoring end. The VersiVision design provides plug-and-play, adjustment-free installation, while LED indicators provide immediate system operating status.
Digitally Encoded HD-TVI Video
The HDTVITR4A03 supports 8-bit digitally encoded HD-TVI video and is directly compatible with NTSC, PAL, and SECAM camera systems. The optimized optical modules support 1280H/25F, 1280H/30F, 1280H/50F, and 1280H/60F video formats.
Bi-Directional RS-485 Data Transmission
In addition to four HDTVI video channels, the HDTVITR4A03 provides one channel of bi-directional RS-485 data. The data interface supports rates up to 300 Kbps, with RS-232 or RS-422 available as optional interfaces.
This allows the fiber link to carry video together with compatible camera control or other serial data.
Multimode Fiber Transmission
The 4-channel multimode HDTVI + data configuration supports transmission over one multimode optical fiber. The product model table identifies the HDTVIT4A03/HDTVIR4A03 transmitter and receiver pair as using 850/1310nm optics with a maximum distance of 1 km.
Plug-and-Play Fiber Optic Installation
The VersiVision HD video platform is designed for straightforward installation without electrical or optical adjustments. LED indicators provide instant system monitoring, and the units can be deployed as standalone devices or installed in the FVC18 rack-mount chassis.
