<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>

Experience 5MP full HD color video and the simplicity of reusing existing coaxial infrastructure with HDCVI. The full-color starlight HDCVI camera presents a high quality color image with rich details even in total darkness conditions. It offers various fixed lens models with a multi-language OSD and HD/SD switchable output. It adopts two powerful warm white LED illuminators, covering an effective range up to 40 m (131.23 ft). The LEDs switch on automatically in darkness to capture detail-packed fullcolor images 24/7, ensuring anthentic identificaiton of objects. It is an ideal choice for applications such as schools, retail centers and parking lots.

• Full-color starlight
• 40 m LED distance
• Max. 20fps@5MP
• CVI/CVBS/AHD/TVI switchable
• Built-in mic (-A)
• 3.6 mm fixed lens
• IP67, 12V±30% DC

Full-color Starlight
The camera adopts F1.2 large aperture lens and 1/2.7" high performance sensor. With higher amount of absorbed light and advanced image processing algorithm, the camera presents an impressive lowlight performance with an exceptional balance between noise reduction and the blur of moving object.

Warm Supplemental lights
With two warm supplemental LED lights, the camera is able to provide a coloful and vivid image even in total dark. By default, the camera is set to smart light mode, in which the camera can automatically adjust the exposure time and light sensitivity simultaneously to avoid overexposureing of the objects in the image center. Also, the sensitivity and intensity of the LED lights can be remotely controlled by OSD menu.

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. *This function is available for select models.

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. *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 700 m for 5MP HD video via coaxial cable, and up to 300 m 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.

Multiple-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 most end users’ existing HD/SD DVRs.

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. 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 mostunstable power supply conditions. Its 4KV lightning rating provides protection against the camera and its structure from the effects of lightning.
