      Dahua 4MP ePoE Starlight+ Network Dome Camera

      The Dahua 4 MP Starlight+ ePoE camera offers Analytics+ functions at the edge – performing complex real-time face capture, people counting, and perimeter protection surveillance. The Dahua Analytics+ algorithms significantly improve accuracy and reliability as compared to standard intelligent features. The camera is ideal for a host of diverse applications — Starlight+, True Wide Dynamic Range, and Smart IR technologies allow the camera to operate in any lighting condition and the IP67 and IK10 rating make the camera suitable for the harshest environments. 

      Key Features:

      • 1/1.8-in. 4 MP Progressive-scan CMOS Sensor 
      • Triple-stream Encoding 
      • Smart H.265+ and Smart H.264+ Dual Codec 
      • 4 MP (2688 x 1520) at 30 fps, 2.7 mm to 12 mm Motorized Vari-focal Lens 
      • Enhanced Power and Data Transmission Distances (ePoE) 
      • Starlight+ Technology for Low-light Applications Analytics+ Functions — Face Capture, Metadata Extraction,  People Counting, and Perimeter Protection 
      • True Wide Dynamic Range (120 dB) and Day/Night IR Cut Filter 
      • Maximum IR LED Distance 45 m (147.64 ft) 
      • IP67 Ingress Protection and IK10 Vandal Resistance 
      • Intelligent Video System
      Face Capture

      Dahua AI Face Capture technology automatically captures faces from a digital image or from a video frame. The camera employs advanced algorithms to locate faces quickly and accurately from the source video and then captures the facial image. 

      Metadata Extraction

      Once the camera captures a facial image, it analyzes the face and extracts six attributes — age, gender, expression, and whether the target face wears glasses, wears a mask, or sports facial hair. 

      People Counting

      The camera uses complex real-time people counting algorithms to deliver accurate flow statistics from two distinct people counting functions, Line Crossing and Regional. The line crossing function counts the number of people crossing a defined line, and the regional function counts the number of people in a distinct, user-defined area. People counting is ideal for measuring the number of customers entering or exiting a location and to monitor groups of people in a distinct location.

      Perimeter Protection

      Dahua Analytics+ includes Tripwire and Intrusion functions that offer custom tripwires based on object type for automation in limited access areas. Perimeter Protection requires less pixels to detect an object to deliver improved accuracy and decreased false alarms due to lights, weather, trees, or animals. 

      Enhanced Power over Ethernet (ePoE) Technology

      Dahua's innovative ePoE technology offers a plug-and-play solution to transmit power and data over long distances via Ethernet or coaxial cables, reducing installation time and saving money. ePoE technology is a viable, cost-effective solution for extending transmission distances and for converting existing, coax-based analog systems into IP systems. For video security and surveillance installers, ePoE technology saves time and money by reducing overall cabling requirements, allowing for existing coax cable to be used, and minimizing the number of peripheral devices needed. For new installations, ePoE offers the ability to design long-distance applications without the need for additional repeaters.

      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 conditions. The camera uses a set of optical features to balance light throughout the scene, resulting in clear images in dark environments.

      Smart H.265+

      Smart H.265+ is the optimized implementation of the H.265 codec that uses a scene-adaptive encoding strategy, dynamic GOP, dynamic ROI, flexible multi-frame reference structure and intelligent noise reduction to deliver high-quality video without straining the network. Smart H.265+ technology reduces bit rate and storage requirements by up to 70% when compared to standard H.265 video compression.


      Dahua cameras operate in extreme temperature environments, rated for use in  temperatures from –40° C to +60° C (–40° F to +140° F). The camera complies with an IK10 impact rating making it capable of withstanding the equivalent of 5 kg (11.02 lbs) of force dropped from a height of 40 cm (15.75 in.). Subjected to rigorous dust and water immersion tests and certified to the IP67 Ingress Protection rating makes it suitable for demanding outdoor applications.
