System Overview
The DHI-ITC431-RW1F-IRL8 is a license plate recognition with a recording resolution of 4 MP at 25 frames per second with a 1/1.8-in. CMOS sensor. The camera includes a 10 mm to 40 mm motorized vari-focal lens that provides long-range video capture. The camera comes in a rugged, IP67-rated housing and offers IR illumination making the camera suitable for most harsh environments and dark applications. The License Plate Recognition camera captures and recognizes license plate alphanumeric characters from a distance of up to 25 m (82 ft) and at vehicle speeds of 120 kph (75 mph).

Functions

License Plate Recognition
The camera automatically captures vehicle license plate images and recognizes license plate numbers and letters. During playback, an operator can perform a license plate search by Time and Date to view thumbnail images of all plates captured during the specified time period or can enter a license plate number to search for vehicles recorded with that plate. License plate recognition technology offers effective entrance/ exit management, traffic surveillance, and parking lot monitoring.

High Efficiency Video Coding (H.265)
The H.265 (ITU-T VCEG) video compression standard offers double the data compression ratio at the same level of video quality, or substantially improved video quality at the same bit rate, as compared to older video compression technologies. H.265 offers such impressive compression by expanding the pattern comparison and difference-coding, improving motion vector prediction and motion region merging, and incorporating an additional filtering step called sample-adaptive offset filtering.

Cybersecurity
Dahua network cameras are equipped with a series of key cybersecurity technologies including: security authentication and authorization, access control, trusted protection, encrypted transmission, and encrypted storage. These technologies improve the camera's ability to prevent malicious access and to protect data.

Environmental
With a temperature range of -40 °C to +65 °C (-40 °F to +149 °F), the camera is designed for extreme temperature environments. Subjected to rigorous dust and water immersion tests the camera suitable for the most demanding outdoor applications. The camera carries an IP67 rating that ensures protection from total dust ingress and protection from water immersion between 15 centimeters and 1 meter in depth.
