Network DVR: HIKVISION/ULTIMAX DS-7308HI-S H.264 (8-ch.)

Hikvision 73... DVRs make a family of cutting-edge digital CCTV recorders using H.264 compression.

HIKVISION DS-7308HI-S is the lowest model from the 73... series of 8-channel DVRs. It can record images with 4CIF (704 x 576) resolution at 8 fps or with 2CIF (704 x 288) resolution at 16 fps. It is suitable for CCTV systems in environments that do not require high dynamic parameters. The device supports all advanced functions implemented in higher models of HIKVISION DVRs, first of all - local recording and network transmission based on H.264 algorithms, providing good video quality at substantially lower bitrates than the previous standards, saving available disk capacity and bandwidth of the network.

HIKVISION recorders are known worldwide not only for their high performance and best technical parameters, but also for high quality.

A new menu has been designed to help everyone, even the beginner user, navigate and make required changes to the settings of the DVR. Both the location of frequently used functions and graphic layout meet the highest current standards.

Browsing the archives locally allows to play them back simultaneously from all channels. For quick location of the interesting moment/period, the recorded video record is presented on a timeline (length - 24 hours). Clicking on any point causes an immediate playing of the recordings. The pace of playing is easy to adjust with the jog dial situated on the front panel.

Undoubtedly, the strongest feature of HIKVISION DVRs, which distinguishes them from competitors, is the opportunity to work on the Internet. Multiple levels of security, individual access rights for different users, stable operation in the network - all this shows that the products are ahead of all other equipment on the market.

HIKVISION DVRs connected to IP network are managed by iVMS software. The software enables the user/administrator to fully configure and manage HIKVISION and ULTIMAX DVRs, ULTINET video servers, and ULTICAM cameras.

DVRs of 73... series have Dual Stream function (two streams of data with independently determined parameters). DS-7316HI-S supports the auxiliary stream in QCIF resolution.

HDD capacity calculation: assessment of the total volume for recording video data requires adoption of certain record parameters and video storage time. The formula below gives the amount of disc space (in MB) for saving one hour recording from one channel:

qi= (di*3600)/(8*1024)

where di means bitrate in kbps. The bitrates of HIKVISION DVRs can be selected from 32 kbps to 8000 kbps.

The iVMS4000 program allows to get access to up to 50 DVRs. The program allows to create user accounts with different privileges, from "administrator" with full rights to "guests" with individually granted access to certain functions.

iVMS4000 software allows to manage HIKVISION DVRs. A wide range of possible settings and functions includes:
