Dahua, the major producer of community movie surveillance tools, the organization has a complete 4K H.265 product portfolio. DH-IPC-HDBW2831R-ZAS-S2, a 4K H.265 network digicam utilizes 12 megapixel (4096×2160) CMOS picture sensor with extremely minimal mild functionality, equipped with Dahua F1.5@two.7 mm-13.five mm Motorized vari-focal lens. This digital camera has great warmth-dissipation efficiency, white colour steel housing, after the long-time procedure, the stability camera’s temperature keeps steady. In conditions of its interface, it has a one Gigabytes (ten/100M/1000Mbps) RJ45 port, 1x RS485, 2CH Audio Input, 2CH Alarm Enter, 1CH Alarm Output, simple for set up.
Outstanding photograph high quality, lower bandwidth
As the crucial factor of its functionality, we take a look at its image resolution. Mounted a Dahua F1.5@two.seven mm-thirteen.5 mm Motorized vari-focal lens, below the minimal optical zoom, the digicam aims at 4K graphic resolution screening card.

In get to take a look at its community bandwidth, we permit the Surveillance camera keep track of the out of doors traffic road, in 4096*2160@25fps, 6Mbps parameter, we employing the bit-fee calculating software program to examine its bitrate managing, we locate its bitrate is stabilized approximate six.6Mps, inside five.three-6.8Mbps, adopting the H.264 Substantial profile encoding, high compression ratio, ultra low bitrate then set the movie parameter to 4096*2160@25fps, 4Mbps, swap to H.265 encoding, we find the bitrate is stabilized within 4.4Mbps. Total, its video clip stream performance is great, specially in H.265 encoding mode, this network camera’s ROI encoding, guaranteeing the image good quality of critical information, drastically saved online video storage.

Outstanding movie surveillance surroundings adaptation

Extensive Dynamic Variety (WDR) technology can maintain suitable image brightness and exposure, also the distinction and ensures picture clarity. Substantial Light-weight Payment (HLC) perform permits digital camera to detect the robust places (the above-publicity part of impression), then reduce the brightness of the sturdy places to increase the overall images. This operate is made to permit protection cameras capturing car plate license. Furthermore, DH-IPC-HDBW2831R-ZAS-S2 also assist BLC, digital Defog features.
Great minimal light-weight functionality

We put the digital camera into the tests box, steadily lowering the illumination to simulate a darkish atmosphere, before switching to night mode (B/W), with help of AGC controlling, this IP camera can keep good photo good quality with coloration images, no image noise and color distortion difficulties when illumination techniques to .008Lux, the community cameras immediately switches to night mode we also locate in order to obtain colour impression, the minimum illumination is approximate .008Lux.
Intelligent Video Investigation (IVA)
