IP监控作为必然的发展趋势，在此就免去累赘叙述。今天，我们谈论的是混合DVR能否成为从模拟监控到IP监控过渡的桥梁。
事实上，混合DVR已经成为主流，它可以让你直接连接模拟和IP摄像机，并能进行实时存储，查看和管理视频。据 Honovich介绍，这些系统拥有良好的用户界面和分析能力，能够远程观看，并且能够存储、连接访问控制系统和第三方设备。
“两年前，(这些装置)被分成约百分之七十的普通编码器和百分之三十的混合编码器，”高德纳公司分析师杰夫•韦宁说，“但是现在市面上的产品中则为约百分之六十的混合编码器和百分之四十普通编码器。”
As an inevitable development trend, IP monitoring is free from redundant narration. Today, we're talking about whether hybrid
DVRS can be a bridge between analog monitoring and IP monitoring.
In fact, hybrid DVRS have become mainstream, allowing you to connect directly to analog and IP cameras and to store, view, and manage video in real time. According to Honovich, these systems have good user interface and analysis capabilities, can be viewed remotely, and can store and connect access control systems and third-party devices.
"Two years ago, about seventy percent of (these) were divided into normal encoders and thirty percent of hybrid encoder," gartner analyst Jeff WeiNing said, "but now the products are available in the market for about sixty percent of the hybrid encoder and forty percent of normal encoder."
因此，最适合你的选项是哪一个?首先，考虑摄像头个数。一台典型的混合DVR能够支持大约16个模拟监控探头和8个IP监控探头，系统集成商奥特系统总裁Tim Feury 介绍说。举例来说，他最近的一个客户——某医院要用到96个监控探头，Feury将需要三至六个混合DVR。相反，如果使用视频服务器和一个中央服务器。 “我会记录到每一个产品，而使用视频服务器，我可以作为一个系统来管理它，”他补充说，一旦超过50个摄像头，优势往往转移到视频服务器上。
还要考虑到帧率的问题，他说，因为混合DVR有一个最大的帧速率。例如，一个混合DVR可以支持24个监控探头，但最大帧速不能超过每秒30帧。
虽然所有的传统供应商都能提供混合DVR，Feury说，但不是所有的网络视频管理软件都能支持混合NVR 。因此，如果你选择不提供混合单元的网络视频管理软件，那你必须选择视频服务器。同等重要的是你要明白何种IP监控探头能够支持NVR
每个模拟监控探头的编码器成本大约在300到400美元之间，加上网络视频监控管理软件和硬件的成本，一套混合视频监控系统的成本大约在5000到10000美元之间，Feury说，这其中包括16个模拟监控探头、存储设备和管理软件。另外还有一些知识产权许可费，和其他额外的费用。
So, which option is best for you? First, consider the number of cameras. A typical hybrid DVR can support about 16 analog monitoring probes and eight IP monitoring probes, says Tim Feury, President of systems integrator otr systems. For example, one of his most recent clients, a hospital, USES 96 surveillance probes, and Feury will need three to six hybrid DVRS. Conversely, if you use a video server and a central server. "I'll record to each product, and the use of video server, I can act as a system to manage it," he added, once more than 50 cameras, strengths are often transferred to the video server.
Also consider frame rates, he says, because hybrid DVRS have a maximum frame rate. For example, a hybrid DVR can support 24 monitoring probes, but the maximum frame speed cannot exceed 30 frames per second.
While all traditional vendors can offer hybrid DVRS, Feury says, not all video management software on the web can support hybrid NVR. Therefore, if you choose network video management software that does not offer mixed units, you must choose video server. It is equally important to understand which IP monitoring probes support NVR
Each simulation monitoring probe of encoder cost between $300 to $400, plus the cost of network video monitoring management software and hardware, a set of mixed video monitoring system costs about $5000 to $10000, between Feury said, including 16 analog monitoring probe, storage equipment and management software. There are also licensing fees for intellectual property, and other additional fees.
