网络监控常用设备
1. 网络监控常用设备
1. Common network monitoring equipment
网络监控系统是由很多不同的设备组成，主要包括摄像头、录像机NVR（或普通pc机加客户端）、交换机（需根据摄像头数量和码率进行调节）、硬盘、显示器、网线、电源护套线、电源配适器（或12V直流开关电源）、摄像头支架等。
Network monitoring system is composed of many different devices, mainly including camera, video recorder NVR (or ordinary PC plus client), switch (need to adjust according to the number and code rate of cameras), hard disk, display, network cable, power sheath cable, power adapter (or 12V DC switching power supply), camera bracket, etc.
2. 摄像机安装方式
2. Camera installation mode
前端摄像机在供电正常的情况下，通过网线和交换机可以将捕捉到的信号传输至后台的硬盘录像机中进行预览和存储。针对监控系统点位的不同，连接方式有所不同。
Under normal power supply, the front-end camera can transmit the captured signal to the background hard disk recorder for preview and storage through network cable and switch. According to the different points of the monitoring system, the connection mode is different.
（1）确定摄像机的安装位置和监控区域，将摄像机通过摄像机支架固定到建筑物或监控立杆上；
(1) Determine the installation position and monitoring area of the camera, and fix the camera to the building or monitoring pole through the camera bracket;
（2）确定后台设备（硬盘录像机和显示器）的摆放位置，硬盘录像机安装好后需要为后台设备提供电源插排；
(2) Determine the location of the background equipment (DVR and display). After the hard disk video recorder is installed, it is necessary to provide power plug for the background equipment;
（3）前后端都准备好之后，就需要布线，线路分为两部分：首先确认好交换机的位置，需通过网线将每个摄像机连接到交换机，还需要将网络硬盘录像机跟交换机联通，要本着走线和美观、安全的原则走线；其次，摄像机电源供电线布线，每个摄像头都需要一个12v/1A或2A的电源配适器，看施工环境或成本需求，可以用开关电源代替，需另配电源插头。
(3) After the front and rear ends are ready, wiring is required. The line is divided into two parts: first, confirm the location of the switch, connect each camera to the switch through the network cable, and connect the network hard disk recorder with the switch, which should be in line with the principle of wiring, beauty and safety; secondly, the power supply line of the camera should be wired, and each camera needs a 12V /1A or 2A power adapter, depending on the construction environment or cost requirements, can be replaced by switching power supply, need to be equipped with a power plug.
