The Hikvision DS-2CE56H0T-ITMF M75293 camera can be used in video surveillance systems based on various types of DVRs. The user can select the required video standard from among HD-TVI, HD-CVI, AHD, or the legacy CVBS (ANALOG). The choice of the standard is made by the micro-switch located on the additional cable. The enhanced video systems allow for using the 5 MP resolution of the camera (there are 4 MP and 2 MP options as well). Thanks to high sensitivity of the image sensor (0.01 lx) and built-in IR illuminator made in EXIR 2.0 technology with range up to 20 m, the camera provides high quality video coverage even in difficult lighting conditions.
High-quality video encoding
High Definition Transport Video Interface (HD-TVI) is a new technology that allows users to send uncompressed, high-resolution video 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.
Setup via DVR
The camera provides the ability to control its OSD menu using the video signal cable. The control is possible via a compatible DVR, after selecting PTZ control in its menu and switching on the menu of the camera, with access to all configuration options.
Main advantages of HD-TVI systems
- no delay
- natural live image due to lack of video compression
- video transmission via coaxial cables
- high resolutions: 720p, 1080p, 3 MP, 4 MP, 5 MP
- tribrid DVRs – support for HD-TVI, CVBS and IP cameras,
- high resistance to electromagnetic interference through the use of QAM synchronous amplitude modulation and separation of luminance and chrominance signals
- much easier configuration compared to systems based on IP protocol
- two-way communication – access to OSD menus of cameras and PTZ control via the video cable, directly from the HD-TVI DVR
- maximum video transmission range longer than in the case of CVBS signals
