      Dahua 4MP Enhanced Starlight Network PTZ Camera (25x)

      The Dahua 4 MP ePoE camera offers Analytics+ functions at the edge – performing complex real-time face recognition, 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 — Ultra 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 
      • Five-stream Encoding 
      • Smart H.265+ and Smart H.264+ Dual Codec 
      • 4 MP (2688 x 1520) at 60 fps Maximum Resolution 
      • 2.7 mm to 12 mm Motorized Vari-focal Lens 
      • Enhanced Power and Data Transmission Distances (ePoE) 
      • Analytics+ Functions — Face Recognition, People Counting, Perimeter Protection, and Image Attribute Extraction 
      • Ultra Wide Dynamic Range (140 dB) and Day/Night IR Cut Filter 
      • Maximum IR LED Distance 40 m (131.23 ft) 
      • IP67 Ingress Protection and IK10 Vandal Resistance
      Face Recognition

      The camera includes human facial feature extraction, real-time facial snapshots, and supports a database of up to 200,000 face images and five (5) libraries. The feature enables a pro-active way to identify persons of interest before an incident occurs. The advanced processor extracts and categorizes various features, including age, gender, expression, and whether the target face wears glasses or sports facial hair. The camera is ideal for applications that require entrance/exit management, where knowing who is coming and going is a valuable asset.

      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..

      Perimter 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. 

      Image Attribute Extraction

      Analytics+ allows the camera to classify images in a video stream and then extract and store attributes and features for a specific image. The camera can distinguish between vehicle and human objects, track the object in real-time, and extract attributes, such as vehicle type, color, and make; or gender, clothing color, and facial attributes for people.

      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 new installations, ePoE offers the ability to design long-distance applications without the need for additional repeaters.

      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.
