Dahua 4MP Starlight Corner Network Dome Camera
The Dahua 4 MP Corner Network camera offers Analytics+ functions at the edge – performing complex real-time perimeter protection surveillance and people counting. The camera uses fisheye lens and on-device distortion correction to deliver a wide-angle view. The camera is ideal for a host of diverse applications — Starlight+, Ultra Wide Dynamic Range, and covert IR technologies allow the camera to operate in any lighting condition, while the IP67 and IK10+50J rating protect the camera from environmental elements and vandalism making the camera ideal for use in prisons, hospitals, and other challenging applications.

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. In addition, The camera uses complex real-time people counting algorithms to deliver accurate flow statistics from two distinct people counting functions, Line Crossing and Regional. 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.
Covert IR Illumination
The corner camera offers 940 nm wavelength IR illumination for covert illumination. 940 nm wavelength IR illumination LEDs do not produce any visible glow; they are completely invisible and are ideal for applications that require discrete and covert surveillance such as law enforcement or military uses.
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.
On-Device Distortion Correction
On-device lens distortion correction (LDC) digitally corrects optical distortion common with ultra-wide angle lenses. Enabled by default, the camera displays a 135° Horizontal and 90° Vertical field of view. Other modes are available to increase field of view with greater amount of optical distortion.
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.
The Dahua ArcticPro Series of extreme-environment cameras combine temperature-tolerant components with a waterproof enclosure to ensure flawless operation in temperatures as low as –40°F (–40°C) without the need for an internal heater. The lack of a heater reduces the camera’s power consumption and saves operating costs. 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 the enhanced IK10+50J impact rating making it capable of withstanding twice the impact (50 joules) of the standard IK10 rating. Subjected to rigorous dust and water immersion tests and certified to the IP67 Ingress Protection rating makes it suitable for demanding outdoor applications.
