This is due to their remote accessibility and easy installation setup. Network Video Recorder (NVR) based system has become extremely popular in the business environment. When surveillance staff is on-site they can watch the footage as soon as it has been recorded. This means the video is instantly stored on a hard drive and is easily accessible. Instant surveillance accessibilityĭVR systems are wired so they can directly connect to CCTV cameras. Thus, the DVR system does not offer the sharpness of image details. The analog video results in a lower quality image compared to NVR systems. In DVR systems, the cameras transmit analog video via the coax cable directly to the recorder, and images are processed at the recorder level. On the other hand, the NVR setup at any given time may suffer from signal loss, resulting in downtime or low-quality footage. It can give you live video feeds without any break-ins for round the clock safety and offers a much more reliable connection as they transmit a signal via a wire. While evaluating the reliability of video recording setups between DVRs and NVRs one realises that the biggest advantage of a DVR security system is that it works on its own. The fewer the components, the lesser the replacement cost. The NVR system, however, is cost-effective in the long run because of the reduced need for IT staff to handle and run the system. In comparison to NVRs, DVRs are rather economical, supporting smaller budget requirements. One major difference between DVRs and NVRs revolves around their installation costs. Price is usually an important factor while making a purchase of camera systems. Here are some additional details to get a better sense of how these systems work: Cost-effective system These are also reliable and the oldest type of video recording. These systems record via coaxial cables and use wired security cameras for recording. DVR system – A short guideĭigital Video Recorder (DVR) based systems have been the most common form of video recorders in the industry for a very long time. It is important to understand that a DVR based system is a wired security system, whereas NVR systems can be a wired or wireless system. Both types of video recorders have a central location for footage recording, their ways to process and analyze the video data, however, differs greatly.Īnalog cameras attached to DVRs are responsible for recording data that is further digitized in the video recorder on the other hand, IP cameras attached to NVRs record data in digital form, not requiring a conversion process to ensue. The working mechanisms of video recordersĭVRs (digital video recorder) and NVRs (network video recorder) are what you use to view, manage, process, and store footage videos.
The two most common types are Digital Video Recorders (DVR) and Network Video Recorders (NVR). Understanding how a video recorder works and the various types to choose from will open up a completely new self-help avenue for you.Ī video recorder, being the central processing unit of the surveillance camera provides users with the abilities to view, process and store all the footage recorded.
