Dahua Under Vehicle Surveillance System
Shop on Adorama


The Dahua Portable Under Vehicle Surveillance System (UVSS) uses machine vision technology to take a high-resolution image of the entire vehicle undercarriage to provide a top security solution. Portable UVSS is convenient for temporary vehicle checkpoints, such as exhibition centers, conference halls, temporary bases and bridge checkpoints. The Portable UVSS system includes a monitor, keyboard, mouse, computer, LPC camera, scanning module, tripod and cables. Clear and Sharp Image The UVSS scanning module adopts a high-resolution line scan camera with a low-distortion fisheye lens and long-life LED array lights. Integrated with Dahua advanced distortion correction algorithms, it provides a clear and sharp under vehicle image regardless of tough lighting conditions. Wide Speed Range The recommended typical speed is 50 kph (31 mph) and the UVSS supports up to 80 kph (50 mph) for vehicle image capture in motion. Portable UVSS detects a vehicle's undercarriage image without requiring the vehicle to stop. The UVSS synthesizes the undercarriage image in less than one second. Professional and Accessible Software PC-based software with an easy-to-use GUI provides linear image stitching, plate number integration and live video on the home page. It supports quick retrieval of the history records and checking the under vehicle image details. Integrated algorithm supports images comparison of the same vehicle or recognizing suspicious areas which help operator to improve efficiency. 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. Environmental With a working temperature range from -35deg. C to +70deg. C (-31deg. F to 158deg. F), the UVSS scanning module is designed for extreme temperature environments. Subjected and certified by rigorous dust and water immersion tests, its IP68 rating makes it suitable for most harsh environments.
