A câmera Hikvision DS-2CD2045FWD-I é dedicada para sistemas de CFTV IP. A câmera foi equipada com sensor CMOS de 1/2,5" com resolução de 4 MP e com iluminador IR garantindo boa qualidade de imagem sem iluminação visível dentro do alcance de até 30 m. A built-in 2.8 mm possui ângulo de visão de 109°. A câmera pode operar em ambientes externos ou internos Seu invólucro com alto grau de proteção contra ingresso (IP67) protege os componentes eletrônicos contra condições climáticas adversas.A câmera pode ser alimentada com uma fonte de alimentação de 12 VDC ou via PoE (802.3af).

The camera belongs to the new, EasyIP 3.0 series of cameras, having excellent parameters for affordable price. With Dark Fighter (Ultra-low-light) technology, so far available only in Hikvision Project series, the camera ensures improved color rendition and image quality in low-light conditions. The embedded intelligent image analysis (VCA) includes detection of faces, virtual line crossing, intrusion detection, detection of leaving/taking objects. These features make the camera a perfect tool for implementing advanced video surveillance projects.

H.265/H.265+ - maiores taxas de compressão com a preservação da qualidade de vídeo fornecida por H.264

The camera implements several video compression methods, H.265+, H.265, H.264+, H.264, MJPEG. Compared with H.264, H.265 can reduce by half the data stream, which translates into proportional savings of the disk space or into extended data retention time. H.265+ and H.264+ are Hikvision standards based on the original systems and optimized for CCTV applications. They further minimize the streams in typical video surveillance scenarios. With the advanced video compression algorithms, the camera can be used in IP CCTV systems based on modern NVRs implementing H.265 standard (the DS-76/77/96NI-I/K series supports H.265+, H.265, H.264+, H.264). Of course, the camera can also operate with older models supporting H.264 (the DS-76/77NI-E series supports H.264+, H.264).

O poderoso iluminador IR tem um alcance de até 30 m. O iluminador baseado na mais recente tecnologia de emissão de luz Exir 2.0 tem ca. Eficiência 30% maior em comparação com os arrays tradicionais de LEDs IR. Além disso, a luz infravermelha na forma de um retângulo se encaixa no campo de visão da câmera. Isso melhora ainda mais a eficiência da iluminação e elimina a intensidade de luz excessiva na parte central da cena, típica da maioria dos iluminadores IR. Os iluminadores Exir 2.0 garantem uma uniformidade de luminância muito melhor, incluindo cantos da cena, reduzindo ao mesmo tempo a poluição luminosa no ambiente circundante. Em comparação com a versão anterior, os iluminadores Exir 2.0 oferecem maior vida útil graças à dissipação de calor otimizada, até 20.000 horas.

With the support of ANR (Automatic Network Replenishment), each the IP camera equipped with a memory card can record video in the absence of network connection. After the restoration of the network connection, the recordings are automatically synchronized with those recorded on the NVR. This ensures continuous coverage of events, even in the case of communication problems between the camera and NVR.

The users of Hikvision IP cameras and NVRs can use free Hik-Connect service, which provides remote access to the devices in the case of dynamic IP addresses, or allows for the use of domain names in web browsers. It is necessary to create Hik-Connect account and add the camera. The service can be operated via a web browser or applications (for a PC and smartphone).

Ezviz (EasyVision) is a free service which can be activated in Hikvision NVRs and IP cameras. This free service allows less advanced users to easily access to the video from the cameras via the Internet, without forwarding router ports. To enable remote access, the user should only connect the device to the network (which requires a valid IP address and appropriate gateway settings). The next step is the creation of user account at the www.ezviz7.com website. The account can accommodate devices in a local area network (with activated Ezviz service). The devices will be available from anywhere via the Internet.

SADP (Search Active Device Protocol) is a free and simple to use utility for searching Hikvision IP cameras and Hikvision DVRs/NVRs in the local network. The network device search tool can also be used for modification of network parameters of the Hikvision devices, including the change of passwords or recovery of default passwords. Detailed information on the software and its use is contained in the SADP application - LAN tool for organizing CCTV systems based on Hikvision devices article.
