Hikvision 7716NI-SP/16DS NVR is able to offer 16-channel video simultaneously playback at 1080p resolution.
H.265+ substantially reduces the bitrate of the surveillance video – and radically reduces the bandwidth and storage costs, too. Hikvision H.265+ is an optimized encoding technology based on the standard H.265/HEVC compression. This new line of cameras includes models with 2 MP, 3 MP, 5 MP and 8 MP resolutions. These cameras also feature improved EXIR 2.0” Infrared technology, new low-light technology, 120 dB WDR, expanded Smart analytics, and IP67 protection.
Although both DVR and NVR are recorders for the video surveillance system, but the NVR doesn’t provide the video recording function. After receiving the digital video data from cameras, the NVR writes the data on HDD directly. Compared with DVR, there is no video compression process needed. However, the same as the DVR, the NVR is also responsible for decoding the video. Decoding process happens when users playback the recorded video footage. The performance of NVR’s core processor will determine how many channels the NVR can playback simultaneously. For example,
