Dahua ITC431-RW1F-IRL8 is a purpose-built ANPR traffic camera engineered for accurate vehicle detection and license plate recognition on roadways carrying up to two lanes of traffic. Built around a 1/1.8″ 4MP Starlight CMOS sensor delivering 2688 × 1520 resolution, this camera captures crisp, legible plate images even in demanding lighting conditions, making it a dependable choice for enforcement and traffic monitoring deployments.
At the core of the Dahua ITC431-RW1F-IRL8 is a motorized vari-focal lens with a 10–50 mm focal length, giving installers the flexibility to fine-tune field of view based on road width and mounting height. Paired with four 850 nm infrared illuminators offering an adjustable range of 23–30 meters, the camera maintains reliable capture quality around the clock, regardless of ambient light.
Speed detection is a standout capability of the Dahua ITC431-RW1F-IRL8, supporting a measurement range of 0–180 km/h through video or radar triggering. The onboard intelligence goes beyond basic ANPR, recognizing vehicle type, color, and brand/logo across dozens of manufacturers, while also flagging violations such as speeding, wrong-way driving, illegal lane changes, and motorcycle infractions like missing helmets or unauthorized passengers.
Durability is central to the design of the Dahua ITC431-RW1F-IRL8. With an IP67-rated waterproof housing and IK10 vandal-resistant construction, the camera is built to withstand harsh outdoor environments, extreme temperatures ranging from -40°C to +65°C, and physical tampering attempts — making it suitable for highways, intersections, and toll points in virtually any climate.
Connectivity and data handling are equally robust on the Dahua ITC431-RW1F-IRL8. The camera supports H.265/H.264/MJPEG compression, ONVIF interoperability, and local storage of up to 512GB via TF card, alongside automatic network replenishment to prevent data loss during connectivity interruptions. GPS-based positioning and time synchronization further support accurate, traceable enforcement records.
Whether deployed for speed enforcement, traffic flow analytics, or general road monitoring, the Dahua ITC431-RW1F-IRL8 combines high-resolution imaging, intelligent detection algorithms, and rugged reliability into a single traffic camera solution designed for continuous outdoor operation.
