由于高清DVR无论是分辨率还是图像的流畅度，其要求都要比标清的高很多;另外，高清系统将意味着更大量的数据传输、存储和处理……高清DVR要适应这些要求，它必须具备以下特点：
使用统一的通讯标准
在高清的系统中，各厂商的不同设备要能在同一个系统下和谐共存，这就意味着高清DVR需要采用更统一的标准。目前PSIA和ONIVF等都推出了各自的通讯协议，虽然这两大标准体系还是有些区别，但是比起之前各家标准“漫天飞”的混乱局面还是有了很大的进步。
使用更先进的编***算法
编***算法与高清DVR的发展息息相关。无论是H.264还是MPEG-4，其处理后的高清视频数据量都会对网络和存储带来很大的压力。如果没有更高压缩率、更高效率、更小失真的算法出现，必然会影响高清DVR的快速发展。
更高要求的硬件
集成度更加高、处理能力更加强、模块更加小、功耗更低的硬件，是DVR走向高清的必备要素。除此之外，还要考虑目前国家节能环保的大趋势，采用低功耗、环保的材料。
针对细分市场而定制
随着行业应用的兴起，高清DVR将不仅仅是视音频预览和回放的装置，它还需要与行业应用结合，以满足不同行业的业务管理需求。例如银行ATM专用DVR、超市收银POS专用DVR、环境参数监测DVR、道路卡口车牌抓拍DVR、司法审讯DVR、城管执法手持DVR、车载DVR等等。
High definition DVR requires much higher resolution and image fluency than standard definition. In addition, hd systems will mean more data transfer, storage and processing To meet these requirements, a hd DVR must have the following features:
Use unified communication standards
In HDDS, different devices from different manufacturers can coexist harmoniously under the same system, which means that HDDVRS need to adopt more unified standards. Currently PSIA and ONIVF all launched their own communication protocol, although it is some difference between two standard system, but compared to before each standard "pushing" chaos or has made great progress.
Use more advanced programming algorithms
Programming *** algorithm is closely related to the development of hd DVR. Whether h.264 or mpeg-4, the amount of hd video data that is processed can put a lot of pressure on the network and storage. If there is no algorithm with higher compression rate, higher efficiency and less distortion, it will inevitably affect the rapid development of hd DVR.
More demanding hardware
Hardware with higher integration, stronger processing capacity, smaller modules and lower power consumption is essential for DVR to move towards hd. In addition, we should also consider the current national trend of energy conservation and environmental protection and adopt low-power and environment-friendly materials.
Tailored to market segments
With the rise of industry applications, hd DVR will not only be a device for video and audio preview and playback, but also need to be combined with industry applications to meet the business management needs of different industries. For example, DVR for bank ATM, DVR for supermarket cashier POS, DVR for environment parameter monitoring, DVR for road card grip, DVR for judicial interrogation, handheld DVR for urban management and DVR for vehicle license plate enforcement, etc.
