SD2C400NA-B-PV-PRO is a 4MP WizColor WizSense network PT camera designed for round-the-clock monitoring with exceptional low-light image quality. Combining a large 1/1.8″ CMOS sensor with Dahua’s WizColor technology, this camera is built for properties that need clear, full-color footage even in near-total darkness.
The SD2C400NA-B-PV-PRO delivers 2560×1440 resolution with a fixed 4mm focal length lens, offering a 97° horizontal field of view suited for wide-area coverage of parking lots, building perimeters, or open yards. Minimum illumination is rated at an impressive 0.0005 lux in color mode, dropping to a full 0 lux with the illuminator active, meaning the camera maintains true color imaging where most competitors would switch to black-and-white.
WizColor technology is the standout feature of the SD2C400NA-B-PV-PRO, using an advanced sensor and lens combination to capture vivid, accurate color video in low-light conditions without relying solely on infrared. This is paired with warm-light illumination reaching up to 30m, extending usable night vision range for full 24/7 monitoring.
Intelligence features include deep learning-based human and vehicle classification through SMD 3.0, along with tripwire and intrusion detection via the camera’s IVS engine. Auto Tracking Lite lets the SD2C400NA-B-PV-PRO automatically follow a detected target within its field of view, keeping moving subjects in frame without manual operator input.
Active deterrence capability rounds out the security feature set, with warm-light warning flashes (configurable duration and frequency) and customizable sound warnings that can be imported and set to play automatically, helping discourage intruders before an incident escalates.
PTZ performance covers a 345° pan range and 0° to +90° tilt range, supporting up to 300 presets and 8 tours with up to 32 presets each. Built-in two-way talk, with an integrated microphone and speaker, enables real-time communication for site management or visitor interaction.
Built for durability, the SD2C400NA-B-PV-PRO carries TVS 2000V lightning and surge protection along with waterproof and dustproof construction, and operates reliably across a wide -30°C to +55°C temperature range. Power is supplied via 12VDC or PoE (802.3af), with video compression through Smart H.265+/H.264+ codecs for efficient bandwidth and storage use.
For businesses that need dependable low-light color video with active deterrence built in, the SD2C400NA-B-PV-PRO offers a strong combination of imaging quality and proactive security response.
