There are many more differences between systems that use analog cameras and those that use IP cameras.
– The DVR supports only cameras with VGA resolution – The NVR supports high-resolution megapixel cameras – The DVR uses coax connections to each of the analog cameras
This allows you to take advantage of the existing network infrastructure instead of running wires from a “home base” location to all the cameras. – The NVR connects to the computer network and so does all the IP cameras. Q: What is the difference between a DVR and an NVR?Ī: Here are a few of the many differences between these devices.
Some DVRs connect to the network and can be viewed using a Windows computer. Once you exceed the number of connections available on the DVR, you will need to add another DVR to your system. This means that you have a maximum number of cameras that can be supported by one unit. DVRs are available with 4, 8 16, 32 and 64 channels (or connections). The DVR used in the security market has a fixed number of BNC connections to attach analog CCTV cameras.
The term DVR is also used by the consumer TV market. Q: What is a Digital Video Recorder (DVR)?Ī: The DVR is a device that records video from analog cameras to one or more hard drives. The NVR usually has a fixed limit to the number of cameras it will support. The Video Server usually runs the Windows operating system and is more flexible than the NVR because it is easier to expand and add cameras. You can select the VMS you like and then load it on the Video Server.
The Network Video Recorder comes with the VMS software already installed, while the Video Server does not include the VMS software. Q: What is the Difference between a network video server and the Network Video RecorderĪ: The Video Server is similar to the Network Video Recorder (NVR) in that they both record the video. The computer usually uses Linux, but there are some that use Windows as well.įor a comparison of the Computer Server using VMS and the Network Video Server (NVR), take a look at our review and comparison of various systems.
The NVR includes both the computer and special Video Management Software (VMS). The term evolved from the older DVR (or Digital Video Recorder). It also allows many people to view real time and recorded video. It is similar to the Video Server system, but instead of using a standard Windows computer, it uses a dedicated special computer with an operating system and application software that is dedicated to recording the video. Network Video Recorder (NVR) is a complete system that includes the computer and software and is typically proprietary and not expandable.Ĭloud service provides remote recording (over the Internet) for IP cameras at many different locations.įor more details take a look at our review and comparison of a number of these IP video recording systems.Ī: The Network Video Recorder (NVR) is a complete IP Camera recording device. Video Management Software (VMS) is software only that runs on your Windows computer and can be scaled to any size of system. Each one provides some unique capability. Q: How do you record the video from IP cameras systems?Ī: There are three types of recording systems: Video Management Software, Network Video Recorders (NVR), and Cloud service systems. The video recording system can be either a computer running video management software (VMS, or a Network Video Recorder (NVR). The system also includes some type of video recording system and a number of viewing workstations. What is a CCTV System? Q: What is an IP camera system?Ī: An IP camera system consists of a number of network attached cameras, which are generally called IP cameras. What is the difference between an optical camera and a thermal camera? How much bandwidth is required on my network to support IP Cameras? What is the difference between a DVR and an NVR?
