Functions:
Micro Four Thirds System
This Dahua camera takes advantage of the The Micro Four Thirds System, an interchangeable-lens photography system that offers superior picture quality from a smaller lens. This system offers nine times the surface area and pixel size of the standard 1/3-in. sensor commonly used in video surveillance applications. The larger surface area and pixel size increases the light gathering capability of the sensor to deliver color images in ultra-low light conditions in the 8MP camera class when other cameras have switched to monochrome.
4K Resolution
4K resolution is a revolutionary breakthrough in image processing technology. 4K delivers four times the resolution of standard HDTV 1080p devices and offers superior picture quality and image details. 4K resolution improves the clarity of a magnified scene to view or record crisp forensic video from large areas.
Starlight+ Technology
For challenging low-light applications, Dahua’s Starlight Ultra-low Light Technology offers best-in-class light sensitivity, capturing color details in low light down to 0.001 lux. The camera uses a large pixel sensor, smart imaging algorithms and a set of optical features to balance light throughout the scene, resulting in clear images in dark environments.
M43 Lens Interface
The lens is a key component of any security camera and one that directly effects the quality of the image. The Dahua 4K HDCVI box camera features the M43 lens interface, typically found on most SLR cameras. This camera is compatible with all types of M43 lenses, including fixed and vari-focal lenses.
Four Signals over One Coaxial Cable
HDCVI technology simultaneously transmits video, power, data, and audio over a single coaxial cable. Dual-way data transmission allows the HDCVI camera to communicate with an HCVR to send control signals or to trigger alarms. HDCVI along with PoC technology delivers power1 to devices at the edge, simplifying installation.
Long Distance Transmission
HDCVI technology guarantees real-time transmission over long distances without loss of video quality. HDCVI cameras provide the same resolution as most IP network camera systems using existing RG-59, RG-6, or CAT 6 UTP cabling.
Simplicity
HDCVI technology seamlessly integrates traditional analog surveillance systems with upgraded, high-quality HD video, making it the best choice to protect security investments. The plug and play approach enables full HD video surveillance without the hassles of configuring a network.
Multiple Outputs
The camera supports HDCVI and CVBS signal outputs simultaneously with one HDMI connector and one BNC connector. These output signals allow the camera to integrate with various devices, including analog matrix systems and monitors.
