<sub><sup>HDCVI-videovalvonta - uusi askel videovalvontajärjestelmien kehittämisessä, jossa yhdistyvät: korkea kuvan tarkkuus (720P ja 1080P), asennuksen, konfiguroinnin ja ylläpidon helppous sekä HD-CVI-tekniikka on paljon halvempaa kuin IP-kamerat ja NVR.

HD-CVI käyttää patentoitua videonsiirtotekniikkaa, jolla voidaan siirtää jopa 1080p (1920 x 1080) resoluutiota pakkaamattomassa muodossa tavallisilla koaksiaali- tai kierretyillä parikaapeleilla, joita käytetään analogisissa CCTV-kameroissa. Tätä pakkaamatonta videomuotoa voidaan siirtää pidemmillä etäisyyksillä kuin mitä tahansa IP-kameraa. Lisäksi HD-CVI voi siirtää video-, ääni- ja ohjaussignaalit (OSD tai PTZ) yhdellä koaksiaalikaapelilla sen sijaan, että jokaiseen lähetykseen tarvitsisi käyttää erillisiä kaapeleita.

Teknologian ansiosta vanhan analogisen videovalvontajärjestelmän päivittäminen on helppoa ja yksinkertaista. Riittää, että ostat uuden tallentimen eikä montaa valvontakameraa. Samalla säilyy analogisten järjestelmien helppokäyttöisyys HD- ja FullHD-videokuvilla.</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 long-distance and real-time transmission without any loss. It supports up to 800m for 1080P Full 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 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.

Multi-formats
The camera supports multiple video formats including HDCVI, CVBS and other two common HD analog formats in the market. The four formats can be switched over through OSD menu or by PFM820 (UTC controller). This feature makes the camera to be compatible with not only HCVRs but also most end users’ 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.
The camera complies with an IK10 vandal resistance rating making it capable of withstanding the equivalent of 5 kg (11.02 lbs) of force dropped from a height of 40 cm (15.75 in).
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.
