      Dahua 4MP AcuPick Starlight+ Network Dome Camera

      The Dahua 5 MP Active Alarm camera offers Analytics+ functions at the edge – performing complex real-time face capture, people counting, and perimeter protection surveillance. The Active Alarm function responds automatically to triggered alarms using predefined responses. The camera is ideal for a host of diverse applications — Starlight+, True Wide Dynamic Range, and Smart Dual illuminators 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:

      • 1/2.7-in. 5 MP Progressive-scan CMOS Sensor 
      • Triple-stream Encoding 
      • Smart H.265+ and Smart H.264+ Dual Codec

      • IP67 Ingress Protection and IK10 Vandal Resistance 
      • Dual Illumination — IR and White Light
      Face Mask Detection

      The camera captures faces from video images and analyzes the image for the presence of a face mask, useful for maintaining entrance management policies. The camera is capable of detecting a person without a mask at up to 17 feet and sounds a voice alert notifying the person about the absence of a mask. 

      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.

      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.

      Smart Dual Illuminators

      The camera offers both IR and white-light illuminators and intelligently employs each depending on the situation. Typically, the camera enters the IR mode as ambient light decreases. When the camera detects an object entering the monitoring area, it activates the white-light illuminator to capture full-color details. Once the object leaves the area, the camera switches back to IR illumination.

      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.

      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.


      The Dahua ArcticPro Series of extreme-environment cameras combine temperature-tolerant components, a waterproof enclosure, and an integrated heater to ensure flawless operation in temperatures as low as –40° C (–40° F). For applications that demand high-resolution video with advanced features in extremely cold environments, the Dahua ArcticPro Series offers a camera to satisfy the most demanding requirements.


      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.
