| 监控系统是由，监控摄像头、交换机、路由器、网络硬盘录像机等设备组成的。当然不同的应用场景对于监控摄像头的要求也是由可能不一样的。小编这篇文章的目的就是给出监控摄像头在不同应用场景中可能带来差异化体验的规格参数，请结合实际的需求进行选择； The monitoring system is composed of monitoring camera, switch, router, network hard disk recorder and other equipment. Of course, different application scenarios may have different requirements for the monitoring camera. The purpose of this article is to give the specifications and parameters of the monitoring camera which may bring different experience in different application scenarios. Please select according to the actual needs; 1、外形 1. Shape 主要分为两种：筒型和半球型。其中筒型比较常见，室内外通用；半球型一般用于室内，体积较小，可以壁挂或吸顶式安装。 It can be divided into two types: cylindrical and hemispherical. Among them, cylinder type is more common, indoor and outdoor common; hemispherical type is generally used indoors, with small volume, and can be wall mounted or ceiling mounted. 2、供电方式 2. Power supply mode 有DC直流电源供电和POE供电两种，PoE供电相对于直流电源供电，只需连接PoE交换机或PoE网络硬盘录像机即可供电，施工和维护更加简单方便。 There are DC power supply and Poe power supply. Compared with DC power supply, Poe power supply only needs to connect Poe switch or Poe network hard disk video recorder to supply power, so construction and maintenance are more simple and convenient. 非PoE供电：每个摄像头需要电线、网线、PVC套管、插座、安防电源……配件一大堆，线路烦乱，安装复杂，维护不易。 Non Poe power supply: each camera needs wire, network cable, PVC sleeve, socket, security power supply There are a lot of accessories, the circuit is troublesome, the installation is complicated and the maintenance is not easy. PoE供电：一个摄像头一条网线，数据、电力同时传输，简单方便。 Poe power supply: a camera, a network cable, data, power transmission at the same time, simple and convenient. 对比两种供电方式，PoE供电更简洁，成本可能比非PoE供电更低。 Compared with the two power supply modes, Poe power supply is more concise and the cost may be lower than that of non Poe power supply. |
