摄像机BNC转RJ45 视频电源无源双绞线传输器 监控抗干扰 转换器

产品特点：

   *  全能YJS-7001集双线视频传输技术之大成，可接驳任何监控视频设备，同时传输视频、
       音频/电源、控制信号。

    * 采用普通超五类双绞线，可传输远达600米的黑白图像、和500米的彩色图像。短距离时，
       甚至可以采用普通电话线来传输。

    * 传输视频的同时，YJS-7001也能为摄像机等终端提供电源、控制信号，为用户节省大量
      的线路材料成本和建设、维护费用。
 
    * 兼容综合布线标准标准的RJ-45接口、标准的EIA/TIA-568B接线方法、极低的辐射，
       使YJS-7001完全兼容综示布线国际标准，从而使传统的模拟视频、音频、控制、感应
       信号监控与网络、电话融为一体，成为真正一个通用、真正综合的布线系统。

    * 无工具安装直流DC插座设计，配合直流电源跳线设计。YJS-7001成对使用时，后端电
       源直接插入YJS-7001，摄像机端直接用电源跳线连接至摄像机。省却了剥线、上螺丝的
       烦恼，真正实现无工具安装。

    * 可选的简易视频接线座可选的视频接线座，简易的螺丝座设计，仅使用一对双绞线传输
       视频，从而实现“1=4”--一条双绞线传输4路视频，提高了双绞线的传输密度。此设计，
       也使YJS-7001兼容其它无源视频转发器产品。

Features:

   * Great Almighty YJS-7001 double set of video transmission technology， can be connected to any video surveillance equipment， video transmission，
       Audio / power control signal.

    * Ordinary twisted-pair UTP can transmit as far as 600 meters of black and white images， color images and 500 meters. Short distance，
       You can even use ordinary telephone lines to transmit.

    * Simultaneous transmission of video， YJS-7001 can also provide power to the camera and other terminal， a control signal for the user to save a lot
      Line materials and construction costs， maintenance costs.
 
    * Compatible with standard cabling standard RJ-45 interface， the standard EIA / TIA-568B wiring method， low radiation，
       Make YJS-7001 is fully compatible with international standards of comprehensive wire， so that the traditional analog video， audio， control， sensor
       Signal monitoring and network， telephone to become a truly universal， truly integrated wiring system.

    * No tools are installed DC-DC socket design， with direct power supply design. YJS-7001 when used in pairs， back-end power
       Source directly into YJS-7001， the camera is directly connected to the camera with the power jumper. Save the wire and screwing the
       ， Achieve the real install without tools.

    * Optional simple video connect an optional video terminal blocks， simple screw design， using only a single twisted pair transmission
       Video， so that "1 = 4" - a twisted pair transmission 4 video， improves the transmission density of the twisted pair. This design，
       YJS-7001 also compatible with other passive video products.
