Improving Search for License Plates
Monday, 17 February 2020
AXIS Optimizer forensic search plugin provides an efficient means to find video evidence in Milestone XProtect using metadata from automatic license plate recognition (LPR) from Axis and third-party vendors. VMS operators can save significant time and costs using this serverless, camera-based solution for a range of on- and off-street applications. AXIS Optimizer forensic search for vehicles is available to download for free (version 3.5 and up) at www.axis.com/products/axis-optimizer-for-milestone-xprotect.
LPR metadata boosts intelligence in video
Axis cameras with embedded LPR analytics deliver a broad range of metadata — such as type of vehicle, brand, color etc. — that is then stored as search criteria in the VMS database. This makes it possible to search for vehicle-specific metadata in Milestone XProtect derived from AXIS License Plate Verifier (ALPV) from Axis as well as from LPR ACAPs from Vaxtor and FF Group.* Having all data types aggregated in one VMS search database makes for quick, easy and efficient investigations. Combined, this gives XProtect users search results of video based on:
- Vehicle type, brand, model and color
- License plate number and country of origin
- Date and time the video was recorded
Some of the use cases this solution is well suited for include:
- Lane and traffic light enforcement control
- Traffic management
- Toll collection
- Vehicular crime investigations
- Parking lot security
Fast and accurate results
The solution allows users to collect important traffic data and manage all aspects, from automatically detecting license plates to getting forensic search results. Vehicle and plate detection, recognition and classification is performed inside the camera before being sent to the VMS. Using Power of Ethernet IP cameras to process and manage metadata keeps costs low compared to server-based processing.
Plus, each ACAP and camera are optimized to ensure high-quality video and analytics with optical zoom, autofocus, OptimizedIR, electronic image stabilization, shutter speed and other important camera settings. Depending on which ACAP is used, results typically deliver detection rates of >97% with up to 95% recognition rates.
