Product description
The manufacturer specifies this maximum resolution for Hikvision DS-2DF8C448I5XG2/LM-ELW: 2688 × 1520. When assessing scene detail, compare this figure with the image stream options documented in the technical table.
The documented zoom specifications are: 48x optical, 16x digital. Distinguish optical and digital zoom when planning scene coverage, and do not combine separate channel options into a single value.
The documented pan movement range is: 360°，Smart Pan-Tilt Correction. The tilt movement range is: -20° to 90° (auto flip)，Smart Pan-Tilt Correction. Assess these mechanical limits alongside physical obstructions and mounting conditions when positioning the camera.
The manufacturer lists this supplementary illumination range: Laser Distance: up to 500 m. Read values for different channels or illumination types separately, and check on-site lighting and visibility before installation.

| 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 recognize 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. |
