<sub><sup>HDCVI видеонаблюдение – новый шаг развития систем видеонаблюдения, сочетающее в себе: высокое разрешение изображения (720Р и 1080Р), простоту установки, настройки и обслуживания и HD-CVI технология намного дешевле, чем камеры IP и NVR

HD-CVI использует запатентованную технологию передачи видеосигнала, способную передавать вплоть до разрешения видео 1080p (1920 х 1080) в несжатом формате по стандартным коаксиальным кабелям или витая пара, которые используются для аналоговых камер видеонаблюдения. Этот несжатый формат видео может передаваться на бо'льшие расстояния, чем любые камеры IP. Кроме того, HD-CVI может передавать видео, аудио и сигналы управления (OSD или PTZ) по одному коаксиальному кабелю вместо того, чтобы использовать отдельные кабели для каждой передачи.

Технология позволяет легко и просто модернизировать старую аналоговую систему видеонаблюдения. Достаточно приобрести новый регистратор и не сколько камер для наблюдения. При этом сохраняется простота использования аналоговых систем с получением видеоизображения разрешением HD и FullHD.</sup></sub>

4 Signals over 1 Coaxial Cable
HDCVI technology supports 4 signals to be transmitted over 1 coaxial cable simultaneously, i.e. video, audio*, data and power. Dual-way data transmission allows the HDCVI camera to interact with the HCVR, such as sending control signal or triggering alarm. Moreover, HDCVI technology supports PoC for construction flexibility.
* Audio input is available for some models of HDCVI cameras.

Long Distance Transmission
HDCVI technology guarantees real-time transmission at long distance without any loss. It supports up to 700m transmission for 4K and 4MP HD video via coaxial cable, and up to 300m via UTP cable.*
*Actual results verified by real-scene testing in Dahua's test laboratory.

Simplicity
HDCVI technology inherits the born feature of simplicity from traditional analog surveillance system, making itself a best choice for investment protection. HDCVI system can seamlessly upgrade the traditional analog system without replacing existing coaxial cabling. The plug and play approach enables full HD video surveillance without the hassle of configuring a network.

Starlight
With the adoption of large sized high performance sensor, the camera is able to provide incomparable performance even under extreme lowlight environment. The starlight feature allows more details to be captured and accurate color to be recognized at night or in scenes with limited illumination.

Broadcast-quality Audio
Audio information is used as supplementary evidence in video surveillance applications. The HDCVI camera supports audio signal transmission over coaxial cable. In addition, it adopts unique audio processing and transmission technology that best restores source audio and eliminates noise, guaranteeing the quality and effectiveness of collected audio information.

Multiple-formats
The camera supports multiple video formats including HDCVI, CVBS, and other two common HD analog formats in the market. A DIP switch located on the cable allows you to quickly toggle formats, further simplifying installation and debugging. This feature makes the camera compatible with not only XVRs, but also most existing HD/SD DVRs.

Wide Dynamic Range
Embedded with industry leading wide dynamic range (WDR) technology, vivid pictures are achieved even in the most intense contrast lighting conditions. True WDR (120dB) optimizes both the bright and dark areas of a scene at the same time to provide usable video.

Advanced 3DNR
3DNR is noise reduction technology that detects and eliminates random noises by comparing two sequential frames. Dahua’s advanced 3DNR technology allows remarkable noise reduction with little impact to sharpness, especially under limited lighting condition. Besides, the advanced 3DNR effectively decreases the band width and saves the storage space.

Protection
The camera's outstanding reliability is unsurpassed due to its rugged design. The camera is protected against water and dust with IP67 ranking, making it suitable for indoor or outdoor environments. Supporting ±30% input voltage tolerance, this camera suits even the most unstable power supply conditions. Its 4KV lightning rating provides protection against the camera and its structure from the effects of lightning.
