NVR DS-7604NI-E1 / HIKVISION IP Network Video Recorder is a modern IP network video recorder capable of monitoring, recording and playing back images from 4 IP cameras of megapixel resolutions at frame rates up to 25 fps from each camera. This standalone NVR with VGA and HDMI outputs can be directly connected to a monitor, without a need for an additional computer. Thanks to embedded Linux OS, the NVR ensures stable operation and resistance to computer viruses.
The local recording and network transmission uses H.264 or H.264+ compression that provides good image quality with relatively small bandwidth and disk space consumption. H.264+ allows for higher compression ratios in the case of less dynamic scenes, preserving image quality similar to H.264. There is place for one SATA HDD with total capacity up to 4 TB. In addition, the NVR supports NAS (NFS) and SAN (iSCSI) disk arrays. The option of automatic overwriting of existing material prevents loss of the current data. Built-in USB ports can be used for control of the NVR via external devices and for connecting a USB storage device, usually to copy some data.
