Dahua 2MP WDR IR mini bullet network camera

Product Profile

Eco-savvy products use upgraded H.265 encoding technology to bring highly efficient video compression. It saves bandwidth and storage and has an energy-saving design to enhance the monitoring system. Meanwhile, the series offers features such as starlight, Smart IR technology and intelligent image analysis techniques. It provides excellent image quality and intelligent and efficient event reminders. This series provides IP67 weatherproof and IK10 vandal-proof protection features.

Starlight Technology 

Featuring Dahua’s Starlight Technology, this camera is ideal for applications with challenging lighting conditions. Its low-light performance delivers usable video with minimal ambient light. Even in extreme low-light conditions, Starlight Technology is capable of delivering colour images in near complete darkness (0.009 lux). With industry-leading wide dynamic range (WDR) technology, vivid pictures are achieved even in the most intense contrast lighting conditions. For applications with both bright and low lighting conditions that change quickly, True WDR (120dB) optimises both the bright and dark areas of a scene at the same time to provide usable video. 

Intelligent Video System (IVS) 

With built-in intelligent video analytics, the camera has the ability to detect and analyse moving objects for improved video surveillance. The camera provides optional standard intelligence at the edge allowing detection of multiple object behaviours such as abandoned or missing objects. IVS also supports Tripwire analytics, allowing the camera to detect when a pre-determined line has been crossed, as well as People Counting, ideal for business intelligence and Facial Detection, for searching or identification of individuals. 

Environmental 

With a temperature range of -30°C to +60°C (-22°F to +140°F), the camera is designed for extreme temperature environments. Subjected and certified to rigorous dust and water immersion tests, the IP67 rating makes it suitable for demanding outdoor applications. For environments with rain, sleet, snow and fog, an integrated wiper provides users with clear visibility at all times. 

Protection 

Supporting ±30% input voltage tolerance, this camera suits even the most unstable conditions for outdoor applications. Its 6KV lightning rating provides protection against the camera and its structure from the effects of lightning. 

Smart H.265+ 

Deliver high quality video without straining the network, Smart H.265+ is the optimised implementation of H.265. The Smart H.265+ encoding technology includes a scene adaptive encoding strategy, dynamic GOP, dynamic ROI, flexible multi-frame reference structure and intelligent noise reduction, providing saving of up to 70% of bandwidth and storage when compared with standard H.265. 

HEVC (H.265)

H.265 ITU-T VCEG is a new video coding standard which improves compression efficiency, improves robustness and error recovery capabilities, reduces delay with real-time, reduces channel acquisition time and random access delay and reduces complexity.
