Hikvision DS-7732NI-K4 32 Channel NVR

Hikvision DS-7732NI-K4 is a modern 32-channel IP network video recorder capable of monitoring, recording and playing back images from 32 IP cameras of megapixel resolutions, up to 8 MP. Its independent HDMI (up to 4K) and VGA (up to 1080p) monitor outputs can provide images with different layouts. Each monitor can display the video from any camera, in any screen division. Four SATA ports enable the user to install four hard drives, each with a capacity up to 6 TB. Additionally, the NVR supports NAS (NFS) and SAN (iSCSI) disk arrays. In the case of disk space overflow, the newest data overwrites the oldest recordings. Built-in USB ports allow for connecting external memory sticks or disk drives in order to copy some files. The local recording and network transmission can use H.265+, H.265, H.264+ or H.264 compression methods that provide good image quality with relatively small bandwidth and disk space consumption (in each case the selected type of compression must be supported by the cameras). Compared with H.264, H.265 can reduce by half the data stream, which translates into proportional savings of the disk space or extended data retention time. H.265+ and H.264+ are Hikvision standards based on the original systems and optimized for CCTV applications. They further minimize the streams in typical video surveillance scenarios. To use any available compression method, it must be supported by the connected cameras. The compression method can be specified individually for each channel. The NVR supports alarms generated by VCA functions (face detection, license plate recognition, crossing virtual lines, area intrusion detection, an entry/exit to/from an area, loss of focus, etc.) implemented in cameras. The response to such an event (e.g. someone crosses the virtual line in a specified direction) can be the change of the state of the alarm output, email notification sent to a monitoring center etc., depending on the configuration. Advanced analytics allows installers/users to implement more advanced projects, perform quick searches of interesting events and preset intelligent recording that saves disk space. With the support of ANR (Automatic Network Replenishment), any IP camera equipped with a memory card can record video in the absence of a network connection. After the restoration of the network connection, the recordings are automatically synchronized with those recorded on the NVR. This ensures continuous coverage of events, even in the case of communication problems between the camera and NVR. The menu of the DVR has been designed in a manner that helps everyone, even novice users, navigate and make changes to the settings. Both the layout of commonly used functions and graphic design meet the highest current standards. The support for Firefox, Opera, Safari eliminates the need for installing ActiveX components.
