Hikvision DS-7616NI-I2 is a modern IP network video recorder capable of monitoring, recording and playing back images from 16 IP cameras of megapixel resolutions, up to 12 MP. Its independent VGA (up to 1080p) and HDMI (up to 4K) monitor outputs can provide images with different layouts. Each monitor can display the video from any camera, in any screen division.
Two SATA ports enable the user to install 2 hard drives, each with capacity up to 6 TB. The drives can be combined into one group, or one of them can work as redundant or read-only to increase the security of recordings. The user can setup the limit of disk space and assign different volumes for individual channels. 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 uses 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). The H.265 or H.264+ (especially effective in the case of static or quasi-static scenes) coding allows for higher compression ratios with preservation of image quality comparable with H.264. This further saves network and memory resources.
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 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 search 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 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.
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.
The NVR can be managed and operated through a web browser or via free client software: iVMS 4200 (computers), iVMS 4500 (smartphones).
The iVMS 4200 client software enables users of HIKVISION devices to manage them in IP networks. The software allows for configuration and management of NVRs/DVRs, IP and analog cameras (in hybrid systems). The iVMS 4200 utility can remotely manage up to 256 devices, with the use of up to 4 monitors. Oner monitor can display up images from up to 64 cameras. Aside from system configuration and live monitoring, the utility can be used for remote playback, notifying, two-way audio transmission, creating multi-level e-maps.
iVMS-4500 is a mobile application for smartphones running Android, iOS or Windows Phone operating systems. It can be used for live monitoring and playback of images from DVRs, NVRs, IP cameras via Wi-Fi, 2G or 3G networks.
Ezviz (EasyVision) is a free service which can be activated in Hikvision NVRs and IP cameras. This free service allows less advanced users to easily access to the video from the cameras via the Internet, without forwarding router ports. To enable remote access, the user should only connect the device to the network (which requires a valid IP address and appropriate gateway settings). The next step is the creation of user account at the www.ezviz7.com website. The account can accommodate devices in a local area network (with activated Ezviz service). The devices will be available from anywhere via the Internet.
