Dahua IPC-PFW8840-A180 4×2MP WizMind Multi-Sensor Panoramic Network IR Bullet Camera

Launched by Dahua Technology, Dahua WizMind is a full portfolio of solutions composed of project-oriented products including IPC, NVR, PTZ, XVR, Thermal and software platform which adopts industry-leading deep learning algorithms. Focusing on customer’s requirements, WizMind provides precise, reliable and comprehensive AI solutions for verticals. Series Overview The splicing camera supports a 180° panoramic view and 4-channel hardware splicing to realize HD panoramic surveillance. The camera supports crowd situation analysis, vehicle situation analysis, and perimeter protection. It is widely applied in various scenes such as squares, airports, and traffic. Functions Panoramic SplicingWith advanced splicing algorithm, Dahua Panoramic Splicing technology deletes overlapped area and splices multiple images to be a complete panorama. The field of view of the spliced image can be up to 360°, which largely improves surveillance efficiency and user experience. Generally, after splicing, the field of view of four-sensor camera can be 180°, and the field of view of eight-sensor camera can be 360°. Crowd DensityWith deep learning algorithm, Dahua Crowd Density technology can detect the crowd density on the image, and display it on heat map; it can detect people quantity and density in selected area and set threshold. When the number or density is larger or smaller than the threshold, it triggers linkage. Vehicle DensityWith deep learning algorithm, Dahua Vehicle Density technology analyses the vehicle situation in the image, such as vehicle number in selected area. You can set threshold, and when the number is larger or smaller than the threshold, it triggers linkage. IVSWith advanced video algorithm, Dahua IVS technology supports intelligent functions, such as tripwire and intrusion. Smart H.265+ & Smart H.264+With advanced scene-adaptive rate control algorithm, Dahua smart encoding technology realizes the higher encoding efficiency than H.265 and H.264, provides high-quality video, and reduces the cost of storage and transmission. Cyber SecurityDahua network camera is equipped with a series of key security technologies, such as security authentication and authorization, access control, trusted protection, encrypted transmission, and encrypted storage, which improve its security defense and data protection, and prevent malicious programs from invading the device. Protection (IP67, IK10, wide voltage)IP67: The camera passes a series of strict test on dust and soak. It has dust-proof function, and the enclosure can works normal after soaking in 1 m deep water for 30 minutes. IK10: The enclosure can stand the punch more than 5 times from a 5 kg hammer falling from a height of 40 cm (Impact energy is 20J). Wide voltage: The camera allows ±30% input voltage tolerance (wide voltage range), and it is widely applied to outdoor environment with instable voltage.

Hikvision upgrades ColorVu technology for better night vision experience
Hikvision upgrades ColorVu technology for better night vision experience

Hikvision enhances ColorVu, its high quality full-color technology, with Super Confocal and Smart Hybrid Light technologies. With these enhanced ColorVu offerings, even sharper imaging is made possible, with precise focusing in ultra-low light and flexible “hybrid” lighting modes to fit the scenario. “By upgrading ColorVu technology, we aim to elevate our customers’ night vision experience in any setting with always-sharply-focused imaging and versatile lighting options,” says Rubio Hong, the Product Director at Hikvision, “We are very proud of our ultra-low-light technology, which eliminates the headache of darkness and unclear footage.” Improved low-light imaging performance with the Super Confocal Technology Hikvision’s industry-leading ColorVu technology provides full-color footage 24 hours a day, so users see the same sharply rendered images at night as they would see in broad daylight. Now boosted by Super Confocal Technology, ColorVu’s performance in low lighting gets even more stable and precise. As infrared light focuses differently than visible light, it’s very difficult for dual-light cameras to create sharp images in low light. Given that cameras with ColorVu are equipped with large-aperture, high-resolution lenses, the focus depth is too small for the frame, which makes infrared imaging even more difficult. But now, to solve this problem, Hikvision has infused Super Confocal Technology. This is a high-caliber-lens design which reduces optical light dispersion to ensure that the point of focus on the sensor for the infrared light is virtually the same as that of the visible light (thus, “con”-focal). Focusing both types of light at the same spot helps prevent blur and improves the user’s viewing experience by rendering clear, vivid images both in color and black-white. Achieving confocal imaging with F1.0 super aperture is also an industry-first. Flexible lighting options with the Smart Hybrid Light technology Hikvision’s Smart Hybrid Light technology can automatically switch from IR light to visible white (supplemental) lighting at night. Equipped with this technology, cameras offer three supplemental lighting options to suit a user’s unique nighttime scenario, depending on the need. The white or visible light mode establishes color imaging; the IR mode (invisible to humans) enables continual black-and-white imaging at night with no light pollution; and the “smart” mode enables the light to automatically change between the two modes based on perimeter events. With the smart mode turned on, the camera maintains infrared illumination at night until an event triggers color imaging to capture critical details. This means that once human or vehicle motion is detected by the camera, it switches to regular lights and turns to full color. This helps in two critical ways: first, the camera’s color imaging captures better footage which can be used to identify the intruder. Secondly, the triggered light acts as a deterrent to would-be trespassers who might potentially get startled and flee the scene. Great potential for use in both indoor and outdoor applications Recording “no action” footage at night or in poorly lit areas with infrared mode, the cameras’ location won’t be given away, and the chance of a camera being seen and vandalized by intruders is vastly reduced. On the other hand, a bright light triggered by a security event and flooding the area helps deter intruders while recording with the same vibrant, colorful images as in daylight.  Therefore, cameras with ColorVu are ideal for both indoor and outdoor scenarios, such as warehouses, retail stores, public parks, and residential settings, where little or no movement is expected at night but discretion is desired for security cameras. Smart, automated lighting options combined with extremely accurate and sharply-focused details creates a camera that truly goes above and beyond current security industry expectations and performance.
