HD-TVI TURBO HD 3.0 DVR: Hikvision DS-7216HUHI-F2/N (16ch, 3MP@15fps, H.264, HDMI, VGA)

Hikvision DS-7216HUHI-F2/N je 16-kanálový CCTV rekordér schopný nahrávať video v štandarde HD-TVI, AHD, CVBS a IP. Maximálne rozlíšenie záznamu je 3 MP @ 15 fps. V prípade rozlíšenia 1080p / 960x1080 / 720p / VGA / WD1 / 4CIF / CIF je maximálna rýchlosť snímkov 25 snímkov za sekundu.

High Definition Transport Video Interface (HD-TVI) is a revolutionary technology that allows users to send uncompressed, high-resolution video (up to 1080p) over coaxial or twisted-pair cables (using dedicated baluns). The transmitted video signal is in analog form, with bandwidth much greater than in the case of CVBS (SD). As the signal is not compressed, the picture is more natural during live viewing. There is no delay and the configuration of such a system is easier compared to IP CCTV solutions.

The DVR can also record video from AHD cameras. In the case of application of such cameras, it is necessary to set the video mode to AHD. The video mode changes for 2 neighboring video inputs, for example two inputs can be connected to AHD cameras and two to HD-TVI cameras.

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. Support for Google Chrome, Opera and Safari web browsers eliminates the need for installing/using ActiveX controls.

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.

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.

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 DVR can operate in IP networks (TCP/IP or PPPoE protocols), connected via its RJ-45 port. It supports the following protocols and network services: DHCP, SNMP, FTP, SMTP, E-Mail, NTP, DNS, DDNS, UPnP.
The communication can be performed via popular Internet browsers (IE, Google Chrome, Opera, Safari) or free client software (iVMS 4200 for PCs, iVMS 4500 for 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.
