数字监控软件

术语“数字监控软件” refers to a broad category of computer based sets of instructions that provides the instructions for either a computer or a computer based device to operate, control, and/or process binary (digital) data used or created for 安全与监视 purposes. To narrow this definition down a little for the purpose of this 文章, 数字监控软件 is the collective set of programming used to create 数字视频图像 for 安全与监视 purposes.

自言自语“数字监控软件” refer to such a broad definition, it may be easier to explain what it is based on how it is used and what it does. There are basically three broad categories of 数字监控软件. The first applies to 独立的 数字视频 安全与监视 systems; the second applies to personal computer based 数字视频 安全与监视 systems; and the third and final category, for the purpose of our discussion, applies to 智能手机 and similar type devices used with 数字视频 and 监视 software.

独立数字视频安全系统
独立的数字视频安全系统是用于安全或监视目的的一组设备,用于创建可能会记录或可能不会记录的数字视频文件。术语“standalone” indicates that these systems do not require any additional assistance from exterior devices such as a computer. The 数字监控软件 used in these systems can include the 操作系统 of the Digital Video Recorder’s or 硬盘录像机’s and any additional programs used on that system to control the various devices of the 独立的 system

A 独立的 数字视频 安全与监视 system in its basic configuration includes one or more 数码摄像机, a 硬盘录像机 unit with a 数字信号处理器 or 数字信号处理器, and a digital based monitor. In a 独立的 system, the cameras send their 数字视频 data to the 硬盘录像机 where the 数字信号处理器 compiles the data using a 编解码器 or COmpression / DECompression utility to create 数字视频 files. The files are then viewed on the digital monitor and or stored for later use on a hard disk drive on the 硬盘录像机.

The 数字监控软件 in this system can include:
1) The 操作系统 of the 硬盘录像机/DSP unit;
2)编解码器实用程序;和,
3)任何其他专门的指令集来控制设备。

For example, 监控摄像机王offers three major types of 硬盘录像机s; our Elite mini series, or Elite series, and our Ultimate series. These 独立的 systems have a highly specialized 数字信号处理器 that creates 数字视频 files and coordinates the functions between the three major devices of the system. This is usually referred to as the “operating system” and all of our units use a Linux based 操作系统.

编解码器实用程序是一个特定的软件程序,用于将视频数据编译成数字视频文件。数字视频实际上是连续拍摄的几张数字照片。可以使用不同的速率,但是一般标准是每秒29.9帧或fps。这意味着相机在一秒钟内可以拍摄29张数码照片,因此在一分钟的视频中,相机可以拍摄约1800张图片。您会看到文件大小如何在很短的时间内变得非常大。

The 编解码器 uses mathematical algorithms so the file size is a fraction of the original total size. This piece of 数字监控软件 does this with very little loss of quality. There are many different types of 编解码器s such as MJPEG, MPG, H.264, etc.

A 独立的 system may also contain 数字监控软件 that operates the equipment, including specialized functions. For example, Pan-Tilt-Zoom or PTZ cameras can move horizontally, vertically, and can enlarge objects. These movements may be controlled by 数字监控软件.

个人计算机数字视频安全系统
有一些数字视频安全系统可以利用个人计算机代替DVR,DSP和/或监视器。通常,这些系统包含一个PCI卡或类似的印刷电路板,可以执行大部分系统需求,包括存储数字视频文件,控制设备以及在计算机上显示视频’s monitor.

Any of the software associated with these functions, in essence, can be considered 数字监控软件.

智能手机
智能手机需要小型程序才能适应不同的系统和设计或与之交互。这些程序称为应用程序或“apps.” An app can also be of a 数字监控软件 type.
