Dahua SD2C400NA-B-PV-PRO 4MP WizColor PT Network Camera Product Guide
Overview
The Dahua SD2C400NA-B-PV-PRO Pan and Tilt Network Camera delivers advanced active protection for indoor and outdoor security surveillance. This high-performance internet protocol camera captures crisp four-megapixel video clarity. It features a wide-angle twenty-eight-millimeter fixed lens configuration attached to a motorized mechanical head. Integrated smart dual illumination engines work alongside active deterrence mechanisms to intercept security breaches before they occur. It delivers a comprehensive data network defense solution for modern smart homes, corporate perimeters, and retail assets.
Motorized Wide Angle Field Optimization
The motorized mechanical head minimizes operational blind spots across expansive areas. It pans smoothly from zero to three hundred and forty-five degrees horizontally. The vertical tilt axis adjusts dynamically from zero to eighty degrees. Users can manually steer the wide-angle twenty-eight-millimeter lens using a remote smartphone application. This layout combines the broad visibility of a fixed lens with the flexible positioning of a robotic mechanism.Â
Three In One Intelligent Active Deterrence System
This advanced TiOC system integrates multiple preventive safety mechanisms directly into the camera framework. When an intruder breaches a customized perimeter line, the unit activates a bright flashing red and blue light warning strip. Concurrently, a built-in high-power speaker projects a loud customizable voice recording or a piercing siren alert. This immediate combination changes the camera from a passive recording tool into an active real-time crime deterrent.Â
Premium Full-Color Night Vision Engineering
The advanced lighting system removes standard monochrome black and white gray streams from your storage archives. It utilizes specialized light gathering hardware to capture vivid full-color video feeds throughout the night in deep darkness. The system activates gentle warm white light LED emitters dynamically when target activity emerges near restricted boundaries. This capability allows security teams to identify exact clothing color combinations, vehicle descriptions, and suspect faces easily.Â
Advanced WizSense Deep Learning Protection
An onboard deep learning processor actively isolates and classifies human shapes and vehicle profiles within the video frame. It filters out irrelevant environmental triggers such as wind-driven tree branches, raindrops, blowing trash, or stray animals. This precise classification layer drastically reduces annoying false alert notifications sent to user mobile profiles. It ensures that system operators focus attention entirely on actual actionable security threats.

Core Features and Benefits
Full Duplex Sound Pickup and Two Way Talk
The camera includes a premium microphone array that captures clear ambient sound while filtering out constant background echoes. The high-power internal speaker projects immediate real-time vocal responses over long distances. This configuration allows business managers to interview visitors at entry gates or issue verbal warnings to trespassers remotely.
Professional Wide Dynamic Range Balance
Hardware-based true wide dynamic range technology balances contrast variations in highly reflective or backlit environments. The system preserves deep shadow details inside dark shipping bays while muting bright sunlight streams from outer expanses. This processing layer guarantees continuous facial readability across changing daily weather conditions
