4 Camera NVR
Saving videos from IP cameras requires a network recorder to store the high resolution images. For IP technology, these 4 channel NVRs (network video recorders) offer an entry level option for recording and storing megapixel images. A 4 channel NVR can connect up to 4 IP cameras, which will provide good coverage for homes and small businesses.
NVR recorders are needed for IP cameras because they are generally more powerful than their DVR counterpart with increased processing power and more storage space. These network video recorders use built-in software to record from the IP cameras to hard disk drives. Each NVR usually have a list of supported cameras for the recorder.
