Digital Video Recorder (DVRs) and Network Video Recorder (NVRs) are typically what you use to view, manage and store surveillance videos. NVR and DVRs as software programs record video in a digital format to a USB flash drive, disk drive, SD memory card or in any other mass storage device. They are both available in a variety of hard drive sizes and software. They make it much easier to record, save and review video contents. Your choice for one and its functionality largely depends on owning IP or CCTV surveillance cameras. How DVRs and NVRs function. First and foremost, you should know that DVRs and NVRs perform the same function of saving and storing surveillance videos. However, they are designed to work with different and specific camera types. They are both available in three distinct form factors, including, a tower server, a rack mount server or a stand-alone appliance. DVRs are used in surveillance, CCTV or analog systems to record video signals from security cameras. The data, after being captured can be stored and viewed multiple times as a result. Most DVRs have the ability to record audio as well. On most occasions, they provide services and features such as video search by date/time or camera, which surpass the simple video and image recordings. Moreover, DVRs offer control over the frame rate, video quality or overwrite any video which is deemed no longer essential thus allowing the available disk space to be minimized. In particular DVR systems, both the access to security footage and the remote control is possible, and you’ll just need to connect the device to either a LAN or an Internet network. It is worth mentioning that some of the latest digital video recorders come equipped with video analytic firmware and software, thus supporting functionality such as following objects or the suspects throughout your surveillance system. Security DVRs can be classified as either being embedded or PC-based. The architecture of a PC based DVR has a PC with an operating system and a card for video capture meant to capture footage. On the other hand, an embedded DVR functions as a single unit having its operating system and software housed in the firmware.
