Hikvision DS-7216HQHI-K2 is a 16-channel CCTV DVR capable of recording surveillance video provided in HD-TVI, AHD, HD-CVI, CVBS and IP standards. The maximum recording resolution is 1080p@15fps, however channels 1, 2, 3 and 4 can support 3MP@15fps. In the case of VGA / WD1 / 4CIF / CIF resolutions, the maximum frame rate is 25 fps.

H.265 video compression

The DVR can record one or two video streams (primary and/or secondary) from each channel. The video can be compressed with the use H.265 method. Compared with the predecessor (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+ can further minimize the streams in typical video surveillance scenarios.

Special recording modes

The recording can be performed in different modes: continuous, motion detection (with pre- and post-event recording), alarm (with pre- and post-event recording), or 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.

Intelligent image analysis

Two selected channels have the possibility of independent settings for intelligent image analysis (VCA). The video content analysis includes detection of virtual boundary line trespass (including direction), and detection of intrusion to an area of a square shape.
The image quality diagnostic function can e.g. send email or alarm message on a worsened focus, excessive brightness or discoloration.

Refined client software

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. One 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.

Hik-Connect is a mobile application, intended for smartphones running Android or iOS operating systems. It can be used for remote live viewing of images from DVRs, NVRs, network cameras via Wi-Fi, 2G or 3G networks, and for playing back recorded video files. The application connects with the devices by IP addresses and/or through the P2P cloud.
