Описание: This video will compare three different recording devices, a DVR, a NVR, and a POE NVR. They share the same features such as Recording, hard disc drive swapping, and supports VGA and HDMI. They have different features as well. DVR accept analog cameras, converts the analog signal to digital signal; NVR receives digital signal and directly writes on the hard disc drive; POE NVR includes POE switch features, can power terminal devices. Then there will be a simple comparing, how we should choose recording devices depending on our needs.
