How to Design Video Surveillance Solutions 

Video management systems are the hub of video surveillance solutions, accepting video from cameras, storing the video and managing distribution of video to viewers. 

There are 4 fundamental options in video management systems. Most organizations choose 1 of the 4. However, as companies may have multiple types when they transition between one and another. 

DVRs are purpose built computers that combine software, hardware and video storage all in one. By definition, they only accept analog camera feeds. Almost all DVRs today support remote viewing over the Internet. DVRs are very simple to install but they significantly limit your flexibility in expansion and hardware changes. DVRs are still today the most common option amongst professional buyers. However, DVRs have definitely fallen out of favor and the trend is to move to one of the 3 categories below. 

HDVRs or hybrid DVRs are DVRs that support IP cameras. They have all the functionality of a DVR listed above plus they add support for IP and megapixel cameras. Most DVRs can be software upgraded to become HDVRs. Such upgrades are certainly a significant trend and is 

attractive because of the low migration cost (supports analog and IP cameras directly). Learn more about the value and issues in selecting HDVRs. 

NVRs are like DVRs in all ways except for camera support. Whereas a DVR only supports analog cameras, an NVR only supports IP cameras. To support analog cameras with an NVR, an encoder must be used. 

IP Video Surveillance Software is a software application, like Word or Excel. Unlike DVRs or NVRs, IP Video Surveillance Software does not come with any hardware or storage. The user must load and set up the PC/Server for the software. This provides much greater freedom 

and potentially lower cost than using DVR/NVR appliances. However, it comes with significant more complexity and time to set up and optimize the system. IP Video Surveillance Software is the hottest trend in video management systems currently and is the most frequent choice for very large camera counts (hundreds or more).
