This year, Dahua Technology raise HDCVI into the 4K Era. Dahua 4K-HDCVI adopts 4K Ultra HD image acquisition and back-end DVR storage. HDCVI technology architecture overcame the common bottleneck of transmission bandwidth to achieve high-resolution video previously only available on IPC. Dahua delivers altogether six products to demonstrate this breakthrough, extending the potential of HDCVI in future.
Dahua 4K HDCVI offering includes 4K box camera(DH-HAC-HF3805G), 4K IR bullet(DH-HAC-HFW3802E-Z)& dome camera(DH-HAC-HDBW3802E-Z), 4K fish-eye panoramic camera(DH-HAC-EBW3802), 4K multi-sensor 180-degree panoramic camera(DH-HAC-PFW3601-A180), and a series of 4K supported XVR (HCVR7000-4K Series). By deploying superior signal modulation mechanism and noise reduction technique, Dahua 4K Ultra HD solution transmits 4K video signal up to 700m (RG6 cable).
DH-HAC-HF3805G adopts the SONY 4/3” 8MP STARVIS sensor, outputs 3840(H) x 2160(V) ultra-high resolution images, equivalent to the performance of 4X 1080 HD camera, to achieve wide angle coverage and clear video evidence at the same time. This camera also delivers functions like autofocus, image magnification for dynamic detection and a linkage alarm without the need to use with the back-end. Use together with an appropriate housing; this camera is good for outdoor surveillance. Excellent 0.001Lux/F1.2 enables DH-HAC-HF3805G to have good performance and outstanding visibility in difficult lighting conditions.
Another star product is the DH-HAC-PFW3601-A180. Making use of Dahua’s advanced image stitch algorithm to perform 180 degrees panoramic seamless stitching, it is the first HDCVI multi-lens infrared camera with a 4K 180-degree panoramic view. By using three SONY STARVIS sensors and F1.4 large aperture lens, this infrared camera delivers high-quality images even under low light. Working with the 4K backend, panoramic images can offer auto-tracking to realise a multiple target split-screen view using the magnifying tracking. Electronic cruise, a.k.a. E-PTZ is also supported in this case. It will benefit the detection of moving targets in critical areas. In addition, the camera has IP67 and IK10 protection, making it a good choice for important entrances and exits area, city transportation junctions, and parks.
DH-HAC-HFW3802E-Z, Dahua 4K HDCVI WDR IR-Bullet Camera, DH-HAC-HDBW3802E-Z, Dahua 4K HDCVI WDR IR-Dome Camera, and DH-HAC-EBW3802, Dahua 4K HDCVI IR-Fisheye Camera, utilize 1/2” 8MP Sensor to offer wide angle coverage and high-resolution, and all three of them are equipped with IP67 and IK10 protection, making them suit to work in different weathers. With built-in auto-focus lens, DH-HAC-HFW3802E-Z and DH-HAC-HDBW3802E-Z cover different surveillance scenarios with 3.7-11mm focal length. Moreover, Ultra Far Infrared (UFIR) and flat cabling cost are also important highlights of the two cameras. The smart design of DH-HAC-EBW3802 fisheye increases sensor pixel utilisation to 90%, and as a result, this camera recognises a person’s face up to 10m away. De-warping is accomplished in either back-end HCVR70000-4K or mobile client APP. It supports various modes of multi-image de-warping views to suit almost every use.
HCVR7000-4K Series, 4K HDCVI Decoder, deploys H. 264+ to save up to 70% storage space. It supports 4K@15fps encoding and delivers HDMI 4K high-resolution output. 4/8 Channel device support the connection of 4+2/8+4 IPC, and single channel supports up to 8MP resolution. HCVR7000-4K Series has One/Two SATA interfaces and up to 8TB capacity for each disk. It is also equipped with one gigabit Ethernet network interface and support IVS and face detection functions for both analog and smart IP cameras.
