Who has done the monitoring project of parabolic snapshot at high altitude in the community? How to choose a camera? What parameters are needed?

Parabolic objects at high altitude have little to do with cameras, but mainly management software. The black cat guardian surveillance camera factory has an intelligent acquisition card with this function.

The functions are as follows: (1) Brief introduction of the function of intelligent analysis video acquisition card;

1. Face detection: it can automatically detect faces, capture and store face pictures, and capture information conveniently and quickly without watching the whole video, thus increasing search efficiency. At the same time, it can be linked with other set alarm actions, such as pan-tilt rotation amplification, alarm, email, SMS and so on.

2. Suspicious object detection: detect vehicles or other targets that have been parked or stayed for a certain period of time, detect items deliberately placed in a set area, such as parcels or explosives left by people, and call the police.

3. Lost property detection: video signals are collected by cameras and detected by intelligent analysis software. When the target object in the set monitoring area is removed, replaced or maliciously blocked, it will give an alarm to protect property safety.

4. Advanced motion detection: Motion detection can be set in many fields. When people or objects move or change in this area, an alarm can be triggered.

5. Software wide dynamic: adaptive illumination compensation and contrast enhancement are carried out for each pixel value in the digital image, and the processed image can best display all the image details in various outdoor, entrance and other strong light and backlight occasions.

6. Video defogging function: Using image processing vision algorithm, the visibility of the atmosphere is reduced due to fog, haze, rain, dust and other turbid media. In the outdoor monitoring project, the quality of the image collected by the camera decreases, which affects the observation. It can effectively remove the interference, improve the clarity of the scene, enhance the details of the image, and increase the visual comfort of the observer.

7. Tripping line detection: Users can set warning areas or warning lines at will. When a moving object enters or moves to the warning area, the system will automatically mark the moving target and moving track, and the monitoring screen will prompt the alarm information and start the alarm at the same time.

8. Object counting: The shape of moving targets is detected by video analysis, and the purpose of accurately counting moving targets is achieved by setting the number of regions and directions. Can carry out statistics of people flow, traffic flow and density to help analyze business operation.

9. Retrograde detection: detect people, things or vehicles driving in the opposite direction in the specified direction and give an alarm.
