<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 real-time transmission at long distance without any loss. It supports up to 800m(1080P)/1200m(720P) transmission via coaxial cable, and up to 300m(1080P)/450m(720P) 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.

Smart IR
The camera is designed with microcrystalline LED IR illumination for best lowlight performance. Smart IR is a technology to ensure brightness uniformity in B/W image under low illumination. Dahua’s unique Smart IR adjusts to the intensity of camera's infrared LEDs to compensate for the distance of an object, and prevents IR LEDs from overexposing images as the object come closer to the camera.

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.

Multi-language OSD
OSD menu provides multiple image adjustments and function settings to meet the requirements of different monitoring scenes. The OSD menu includes configurations such as backlight mode, day/night, white balance, privacy mask and motion detect. The camera supports 11 languages for OSD menu, namely, Chinese, English, French, German, Spanish, Portuguese, Italian, Japanese, Korean, Russian and Polish.

Protection
With working temperature range of -40 °C to +60°C (-40 °F to +140°F), the camera is designed for extreme temperature 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.
