Digitální videorekordér HD-TVI 8-kanálový Hikvision DS-7208HUHI-F2 / S (5 Mpix, 10 s / s, H.264, HDMI, VGA) TURBO HD 3.0

Hikvision DS-7208HUHI-F2 / S je 8-kanálový rekordér určený pro monitorovací systémy. Umožňuje nahrávat video v normách HD-TVI, AHD, CVBS a IP. Maximální rozlišení záznamu je 5 megapixelů při 10 s / s. Další podporovaná rozlišení: 3 Mpix při 15 s / s nebo 1080p / 720p / VGA / WD1 / 4CIF / CIF při 25 s / s.

The DVR can record one or two video streams (primary and/or secondary) from each channel. The video can be compressed with the use of H.264 or H.264+ method. The H.264+ video compression method has been specially developed for video surveillance systems. This method is especially efficient in the case of static scenes, preserving image quality similar to H.264 but generating considerably smaller data stream, which saves disc space.

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.

Each channel has the possibility of independent settings for intelligent image analysis. The image 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.

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.

SADP (Search Active Device Protocol) is a free and simple to use utility for searching Hikvision IP cameras and Hikvision DVRs/NVRs in the local network. The network device search tool can also be used for modification of network parameters of the Hikvision devices, including the change of passwords or recovery of default passwords. Detailed information on the software and its use is contained in the SADP application - LAN tool for organizing CCTV systems based on Hikvision devices article.
