IP CCTV systems based on Hikvision IP cameras and NVRs can be configured for continuous recording with special parameters in the case of specific events. Each channel can be configured individually in this aspect. It is possible to increase the frame and bit rates, independently of the continuous recording settings. After the occurrence of an event (motion detection, camera tampering etc), the NVR automatically switches to the event-recording mode (usually with higher parameters). During the rest of the time the recording is carried out in the continuous mode. The increased parameters just before and after the event allow to play back every second of the period with high detail and smoothness, while the recordings between events may have a much lower performance, taking significantly less space on the storage media.
HIKVISION NVRs in IP networks can be controlled via IVMS 4200 software. The software allows for configuration and management of NVRs/DVRs and IP cameras. The iVMS 4200 utility can remotely manage up to 256 NVRs/DVRs. The user accounts can have different access/management rights, from the highest level of "administrator" to individually limited "guest" levels.

Hikvision DS-7716NI-E4 is a modern IP network video recorder capable of monitoring, recording and playing back images from 16 IP cameras of megapixel resolutions, up to 5 MP. 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 compression that provides good image quality with relatively small bandwidth and disk space consumption. There is place for four SATA HDDs with total capacity up to 16 TB (optionally: two HDDs and DVD-R/W writer).
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.
