      Dahua 5MP 5-in-1 Network Eyeball Camera

      The Dahua 5 MP 5-in-1 network camera offers multiple features working in tandem to assist with deterrence, low-light detection, active alarm, mask monitoring and two-way talk, the 5MP 5-in-1 camera is a multitasking machine for maximum video surveillance. The camera is ideal for a host of diverse applications — Enhanced Starlight, True Wide Dynamic Range, and Smart Dual illuminators allow the camera to operate in any lighting condition and the IP67 rating makes 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 
      • 5 MP (2592 x 1944) at 20 fps, 2.8 mm Fixed Lens 
      • Analytics+ Functions — Face Mask Detection, Perimeter Protection with Active Alarm, Smart Motion Detection, People Counting, and Face Detection 
      • Built-in Microphone and a Built-in Speaker 
      • Dual Smart Illumination — IR and White Light 
      • Enhanced Starlight Technology for Low-light Applications 
      • Enhanced Power and Data Transmission Distances (ePoE) 
      • ArcticPro Series Camera — Operational down to –40° C (–40° F) 
      • IP67 Ingress Protection
      Active Alarm

      The camera features active alarm functionality to respond automatically to a triggered alarm. The configurable automatic responses include activation of the white-light illuminator to capture color images of the scene and the broadcast of a built-in message or siren. 

      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.


      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.


      Subjected to rigorous dust and water immersion tests and certified to the IP67 Ingress Protection rating makes it suitable for demanding outdoor applications.
