How to differentiate NVR and DVR?

Date: 2016/11/24
Digital video recorders and network video recorders come in various different models and types. Understanding what to look for is important and even more important is understanding what you need. Lets review the various types of CCTV security recorders to better understand what to look for.

Benefits of Surveillance Camera Video Recorders

Camera Channels - NVRs (Network Video Recorders) and DVRs(Digital Video Recorders) come in various sizes. Typically you will see these systems in 4, 8, 16,32,64 and 128 channel (camera) systems. Having 16 channels will allow you to have 16 cameras on one system. This means you can record 16 cameras on one system. Most people tend to go with these recorders because of the large capacity of camera channels they can use. Even if you only need 5 cameras to start, a 16ch NVR or DVR will allow you to have growing room.

NVR vs DVR - The difference between an NVR and DVR can be confusing to many. A network video recorder (NVR) records IP cameras that are transmitted via a network cable. These cameras connect to an NVR either by way of a network switch or router and in some cases directly to the recorder itself. In essence, NVRs record IP cameras. Digital video recorders (DVRs) are synonymous with recording analog or coax based cameras. Newer HD-TVI or HD-CVI,HD-AHD cameras also transmit via coax cable and also use DVRs to record. So in short, a DVR records cameras that are connected via a coax cable. There are more technical details involved explaining the two technologies but for the purpose of this article we will keep it as simple as possible. They both record cameras and offer the same similar options but they record different transmission methods.

Ease of use - Both NVRs and DVRs offer very easy menus to navigate and program the recorders. NVRs tend to be slightly more difficult because the cameras themselves are network devices so they must be programmed with an IP address just like any other device connected to a network. This can cause a little more confusion to customers that are not network savvy. Some systems like this one offer a no-nonsense setup. The NVR itself recognizes the cameras and sets them up for you. This makes using IP camera a lot easier. DVRs are more cut and dry. Cameras do not need to be programmed or set up when connected to the recorder. They are a simple plug and play solution. These security recorders make setup and installation much easier for the DIY customer, as they do not need to mess with camera settings or programming. Both systems offer remote video monitoring and HD recording capability.

What you need to consider when choosing a security surveillance NVR or DVR.

The most important factor when considering a recorder typically is your wiring. Wiring will dictate what you need and what you can use a majority of the time. As an example, if you already have coax cables installed and connected to an older analog CCTV system it would make more sense to use a DVR that supports coax cable already. This will cut costs down, and eliminate the need for running new wiring. Newer HD surveillance camera systems transmit HD video over coax so you can simply swap out your cameras and DVR for newer technology for a fraction of the cost of a new installation. Existing wiring and pre-wired homes or businesses can narrow down your your choice right from the get go
