电话este fibre optic CCTV video products offer a cost-effective and maintenance-free solution for the analogue composite video transmission on a dedicated fibre optic cable. By using digital technology a real-time, 全帧速率, excellent quality and long distance optical transmission can be achieved even with multiplexed video channels including subchannels for audio, 数据和I/O信令. In addition some enhanced models do support a Fast Ethernet bridging allowing a complimentary tunneling of additional IP/Ethernet services. The CFO series products are temperature hardened for operations at -34…+74°C range.
关键 好处
Real time digital transmission
Compared to digital IP video systems with latency, the CFO series transmission provides a real-time operation. The analogue CVBS signals are digitally sampled without deploying any time consuming compression algorithms. High frequency sampling maintains a high quality video content with 全帧速率.
视频多路复用
Digital multiplexing allows simultaneous video operation even with 4 and 8 channels. With dedicated fibre optic cables, the high bandwidth produced is not an issue like in IP networks. In addition system can carry subchannels such as data and audio without any constraints.
可选SFP光器件
The usual challenge on optical transmission is the cable type and required transmission distance. To make the system integration easier, most of the current CFO series links can be equipped with replaceable SFP transceivers. Two-way optical communication is available as either 1-fibre or 2-fibre SFP models both for multimode and single mode fibres.
赠送的以太网
The most enhanced CFO products are having a built-in Ethernet Bridge solution. The interface is a configurable 10/100Base-TX compliant with IEEE802.3 & IEEE802.3U. The bridge has a dedicated 100 Mbps throughput capacity and it is independent of other device functions.
各种服务
Next to video transmission the platform concept supports stereo audio, 串行数据, I/O and Ethernet communication as well. The data channels are configurable for RS-232/422/485 to control e.g. PTZ heads or access system devices. The I/O interfaces can be connected to e.g. PIR sensors or lock systems.
Slick installation mechanics
19-inch 3U installation racks have plenty of space for various link cards and allow mix-and-match type installations. Redundant powering can be achieved by reserving two PSU slots at back. Racks are also available as front or rear loadable versions. Alternatively a single card unit can be installed as standalone by using module adapters. Mini-sized transmitter cards are available for integration inside a CCTV camera housing, 比如.
