An Overview of Video Recorders
Video recorders are essential devices for personal and security use. The most common types of recorders are digital video recorders (DVRs) and network video recorders (NVRs). They can be used to record your favorite shows or to complete home security packages. After recording, different types of storage drives process and save these videos to share with family and friends, or to keep for security reasons.
DVRs and NVRs for Security
Both DVR and NVR systems record video footage from cameras connected to security systems. The main difference between the two is how they process video data. DVR systems process the data at the recorder itself, while NVR systems encode and process the video at the camera and then stream it to the NVR.
Another difference between them is the type of cameras they use. DVRs use analog cameras hardwired to the system. NVRs are versatile because they use IP cameras that can be hardwired or wireless.
After processing the video, there are a few options available for storing your footage. Network storage devices, including personal cloud and network-attached storage (NAS), connect to a large network, allowing more than one device to upload and store both videos and files.
Personal cloud storage servers allow you and your family members to upload and share videos and files. Some servers offer remote options and apps on your phone that allow you to upload on the go from different mobile devices and gaming consoles.
NAS enclosures provide hard drive space for your home or office and include storage up to 256 TB. These can have more than one hard drive, so there's more than enough capacity to store and stream information from more than one person at a time.
