Large Models
| Perimeter Protection |
- Line crossing, intrusion, region entrance, region exiting - Support alarm triggering by specified target types (human and vehicle) - Support combined event alarm triggering - Dedicated large scale AI model for perimeter protection, reduce false alarms by 90% compared to conventional AI cameras - (Wide) VCA range: up to 70 m (nighttime) / 100 m (daytime) - (Tele) VCA range: up to 400 m *Result based on standard setup and test environment |
| Scenario-Aware Object Detection |
This function is based on the large model technology combined with image classification detection. It can automatically detect and identify scene categories in the detection area, including road, intersection, toll station, petrol station, open-air square, vehicle entrance and exit, and person entrance and exit, etc. The PTZ camera will rotate 360° to capture and label the scenes for automatically recognizing the scene information of captured image. - Real-time detection mode: the PTZ camera completes the full-scene capture, detection, and recognition output within 10 minutes in 360°. - Scheduled detection mode: the scheduled time can be set, and pictures can be collected every day or week. The collected pictures will be stored in eMMC, and the detection results will be output at 2 AM by default. The detection results and labels can be uploaded as alarms, and the alarm should include the camera IP address, port No., channel No., capture time, upload time, picture, PTZ coordinates, label ID, label name, and OCR information, as well as the coordinates of each OCR. |
