Dahua has recently released its upgraded full-colour 2.0 network cameras that offer brand new functions – including dual-lens, 4K colour image, vari-focal lens, and AI features – that can significantly optimize surveillance monitoring and benefit end users in terms of clear and colourful image output.
The upgraded colour 2.0 now offers dual-lens cameras with large F1.0 aperture that collects 2.5 times more light compared with F1.6 aperture. Its Dahua Dual Light Fusion capability allows the camera to collect visible colour details and lightness information using separate lenses. These cameras are equipped with dual CMOS (1/1.8-inch and 1/2.8) sensors, providing 36 per cent increase in brightness and 14 times increase in S/N ratio, according to the manufacturer.
With pixel-level frame-by-frame mapping, these dual-lens cameras present high image definition and vivid colours even when the supplementary white light is off, thus reducing light pollution and attraction of insects that can adversely affect the monitoring of the scene. By utilizing the high precision AA (Dahua Active Alignment) process, the lenses and sensors of these cameras are all precisely aligned, ensuring that the scene is captured and restored clearly and accurately.
Meanwhile, the 4K network cameras are equipped with a 1/1.2-inch image sensor. Compared with conventional 8MP camera, this image sensor significantly increases the pixel size by 110 per cent, allowing it to capture real-time 4K colour images even in environments under low-light conditions. This is said to give a 42 per cent increase in brightness and a 400 per cent increase in S/N Ratio, providing a clearer image of the scene.
The upgraded 2.0 network cameras adopt motorized vari-focal lens with 5x optical zoom and auto focus function that Dahua says can maintain clear details of the monitored scene even after zooming in. Dahua says this solves the difficulty in capturing vivid colour details of targets during night-time or in environments with low illumination. The cameras are designed to cover narrow indoor spaces and wide outdoor scenarios, making operation more convenient and saving time and installation costs.
These 2.0 network cameras can work with Dahua 5-I/L series NVRs, which enables colour search of human and vehicle targets and allows extraction of relevant footage. Video analytics options include the colour of the person’s clothes (top and bottom), as well as the colour of car exteriors.
Additionally, another AI feature of this camera series is its AI schedule that allows users to set different AI functions according to the time schedule, providing flexibility in monitoring and greatly reducing operation costs.
