Working With Network Video Recorders
Network video recorders, or NVRs, are useful options if you want to build a highly advanced surveillance system. An NVR recorder works with IP surveillance systems. Thanks to IP cameras and advanced components like NVRs, these IP surveillance systems allow for much higher functionality.
Benefits of Using NVRs
Unlike other systems, such as digital video recorders (DVRs), NVRs don't process the video data; instead, the camera processes video data before it goes to the NVR. The NVR stores the video data and allows for viewing, and is very flexible, so you can use these devices to set up your surveillance system in several different ways. NVRs can connect wirelessly to video cameras, or you can use an Ethernet cable. If you chose, you could set up an IP surveillance system that involves cameras in locations all around the world—all on the same server. You can also take advantage of features such as facial recognition software enabled by advanced IP cameras. Some video management software even sends you an email when alarms trigger.
NAS Servers vs. NVR Devices
Network attached storage (NAS) carries out the same basic role as NVR systems, but with a few notable differences. An NAS is a small computer with private cloud capabilities. It has an operating system, file management options, app functionality, and sharing options. NAS servers are flexible and functional, and can be instrumental in setting up a state-of-the-art surveillance system.
While many different NVR and NAS devices are available, they're mainly set apart based on how many cameras you can connect to the device. There are 4 and 8-channel NVR devices, and even 16-channel models. While it's true that NAS devices feature unlimited camera connections, you also have to set up additional licensing to connect each camera. Most NAS devices come with some free licenses included. Different types of NAS and NVR devices may also feature additional surveillance software, two-way audio communication, and more.
