Plate Recognizer Stream

Easily customize Stream to meet your unique camera, hardware and use-case.

• Prediction Delay  Set the time delay (in seconds) for the vehicle plate prediction. By default, Stream waits at most 6 seconds before it records the plate info. For parking and other use-cases, where the camera can see the vehicle approaching, you can decrease this parameter to speed up the time it takes to open the gate, etc.
• Memory Decay  Set the time between when Stream will detect that same vehicle again. By default, vehicle details stay in memory for 300 seconds. So if the same vehicle is seen within 300 seconds, our engine will capture the plate only once.
• Frame Sampling   Have Stream process every nth frame of a video or camera feed. This can a good way to optimize and minimize hardware resources (e.g. CPU, RAM) in situations where vehicles are driving under 30-40 mph. 
• Without Plates   Detect vehicles without license plates. 
• Detection Zone  Mask out portions of the camera that you want Stream to ignore. 
• Video or Camera  Indicate if you want Stream to process a live RTSP camera feed or any video in ffmpeg format, such as MP4.
• Multiple Videos  Programmatically analyze multiple video files via a CURL command.
• Webhook Parameters  Send webhooks with the original image, just the vehicle image, or no image at all.  Or, easily forward to ParkPow for full ALPR Dashboard and Parking Management features.
• Strict Mode  Accept only license plates that abide to your region’s regular expression of license plates.
• Image Format  Save license plate images in a particular folder with a specific filename. For example, images can be saved as one folder per camera with each image named as camera_timestamp. 
• Save to CSV  Save license plate readings in a simple CSV file.  View “live” CSV file with Notepad++.
