监控安装需要掌握这些知识

Monitoring and installation requires knowledge.

一、区分网络监控和模拟监控：网络监控是网线连接；模拟监控是用同轴电缆连接。网络监控连接头是水晶头；模拟监控连接头是BNC接头。直接看图识别并理解：

1. Differentiation between network monitoring and analog monitoring: network monitoring is a network-line connection; analog monitoring is a coaxial cable connection. The network monitoring connector is the crystal head; the analog monitoring connector is the BNC connector. Directly look at the picture and recognize and understand:

二、网络监控系统水晶头如何制作：

Two, how to make crystal head of network monitoring system:

网络监控系统是通过超五类双绞线等传输介质将前端高清网络摄像机采集的视频信号传输到后端网络硬盘录像机等设备。现在普通都是用的网络监控摄像机了，要想自己安装网络监控，首先你要会水晶头压制。下面直接给大家总结的水晶头接线操作流程。

Network monitoring system transmits video signal collected by front-end high-definition network camera to back-end network hard disk recorder and other equipment through transmission medium such as ultra-five types of twisted pair cable. Nowadays, network surveillance cameras are commonly used. If you want to install network surveillance yourself, you must first suppress the crystal head. Below is a summary of the crystal head wiring process.

虽然我们前面多次提到水晶头制作，但是这里还是要叨叨一下标准568B的线序：橙白-1，橙-2，绿白-3，蓝-4，蓝白-5，绿-6，棕白-7，棕-8。

Although we've talked a lot about making crystal heads, here's the standard 568B sequence: orange-white-1, orange-2, green-white-3, blue-4, blue-white-5, green-6, brown-white-7, brown-8.

三、模拟监控系统BNC接头如何制作：

Three. How to make the BNC connector of the analog monitoring system?

模拟监控虽然我们现在逐步不用了，但是维修工程中还是会遇到，旧的未改造的监控工程很多都是模拟监控系统的。模拟监控是用同轴电缆传输信号，转换接头就是用的BNC接头了，BNC接头制作步骤如下：

Simulated monitoring is not used now, but it will still be encountered in maintenance projects. Many of the old unmodified monitoring projects are simulated monitoring systems. Analog monitoring is to use coaxial cable transmission signal, the conversion joint is the use of BNC connector, BNC connector manufacturing steps are as follows:

四、监控系统设备如何连接：

Four, how to connect the monitoring system equipment:

全套网络监控系统连接和模拟监控设备连接图：

The whole network monitoring system connects and simulative monitoring device connection diagram:

网络监控两种方式，第一种方式：连接路由器，有的人自己家里购买安装可以直接连接路由器，接到电脑上，同样可以远程。

Network monitoring two ways, the first way: connecting routers, some people buy their own home can directly connect to the router, connected to the computer, also can be remote.

第二种方式：连接录像机，通常监控工程都是使用硬盘录像机。

The second way is to connect the VCR, and the general monitoring project is using a hard disk recorder.

五、监控摄像机镜头焦距的选择：

Five, monitor camera lens focal length selection:

监控摄像机主要是定焦镜头，焦距越小，照射越小视角约大；焦距越大，照射距离约远但视角越小。

The monitoring camera is mainly a fixed focus lens, the smaller the focal length, the smaller the illumination, the larger the angle of view; the larger the focal length, the longer the illumination distance but the smaller the angle of view.
