Hikvision DS7204HGHIE1 is a 4 channel tribrid CCTV DVR capable of recording surveillance video provided in HDTVI, CVBS and IP standards. The maximum recording resolution is 720p@25fps. Other supported resolutions are VGA / WD1 / 4CIF / CIF.
High Definition Transport Video Interface (HDTVI) allows users to send uncompressed, highresolution video (up to 1080p) over coaxial or twistedpair 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 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 preand postevent recording), alarm (with preand postevent 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 eventrecording 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 operate in IP networks (TCP/IP or PPPoE protocols), connected via its RJ45 port. It supports the following protocols and network services: DHCP, SNMP, FTP, SMTP, EMail, 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, twoway audio transmission, creating multilevel emaps.
Notice: The DVR does not support HDTVI cameras with 1080p resolution (the video is not displayed or
recorded). The video inputs are combined in pairs, i.e. two neighboring inputs must receive the same kind of signal
(HDTVI or CVBS).
