Hikvision DS-7208HUHI-K2 is an 8-channel CCTV DVR capable of recording surveillance video provided in HD-TVI, AHD, CVBS and IP standards with the max. resolution of 8 MP at 8fps. Other supported resolutions include 5MP@12fps, 3MP@18fps and 1080p/720p/VGA/WD1/4CIF/CIF at 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 using the H.265 method. Compared with its predecessor (H.264), H.265 can reduce the data stream by half, which translates into proportional disk space savings and extended data retention time. H.265+ can further minimize the streams in typical video surveillance scenarios.

Footage can be recorded 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 for specific events. Each channel can be configured individually in this respect. It is possible to change the resolution, quality, and frame and bit rates independently of the continuous recording settings. After the occurrence of an event (motion detection, camera tampering, etc), the DVR 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 with high detail and smoothness, while the recordings between events may have a much lower performance, taking significantly less storage media space.

The Enhanced IP mode allows to increase the number of supported IP channels. It disables smart events in analog channels and limits the HDMI/VGA output resolution to 1080p. The mode can be activated only through direct access to the DVR's menu.

Each channel can be independently set up for motion detection and VQD (video quality detection, which e.g. can send e-mails or notifications to alert the user whenever the image is out of focus, too bright, or discolored).
Two analog channels can be selected to detect virtual line crossing (and its direction) and intrusion within a rectangular area.
Users can also opt for the Enhanced VCA mode, in which virtual line crossing and intrusion detection are available in all channels. If the mode is switched on, the max. input and output resolution will drop to 3 MP and 1080p, respectively.

The iVMS 4200 client software enables users to manage Hikvision devices in IP networks. The software enables the configuration and management of NVRs/DVRs, IP and analog cameras in hybrid systems. The iVMS 4200 utility can remotely manage up to 256 devices on up to 4 monitors. One monitor can display images from up to 64 cameras. Aside from system configuration and live monitoring, the utility can be used for remote playback, notifications, two-way audio transmission, and multi-level e-maps.

iVMS-4500 is a mobile application intended for smartphones with the Android, iOS, and Windows Phone operating systems. It can be used for the remote live viewing of footage from DVRs, NVRs, network cameras via Wi-Fi, 2G, or 3G networks, as well as the playback of recorded video files.

Ezviz (EasyVision) is a free service that allows easy access to camera videos via the Internet, without forwarding router ports. To enable remote access, you only need to connect the device to the network (which will require a valid IP address and appropriate gateway settings). Then create a new user account at the www.ezviz7.com website. The account can accommodate devices in a local area network (with an activated Ezviz service). The devices will be available from anywhere via the Internet.

SADP (Search Active Device Protocol) is a free, easy-to-use utility designed to search for Hikvision IP cameras and DVRs/NVRs in the local network. The network device search tool can also be used to modify device network parameters, e.g. to change or recover default passwords.
