How to purchase panoramic camera

The quality of the lens will greatly affect the quality of the surveillance image. A good lens can achieve HD and more than megapixels, and the higher the frame rate (the speed of animation transmission per second), the better the monitoring process can be. Details of action.

Theoretically, there are two ways to correct the problem of fisheye lens imaging distortion. One is to process the information by the backend platform and restore the imaging; the other is to directly correct in the camera's built-in software and then transmit it to the monitoring backend. . In general, it is recommended to use the latter to solve the problem of fisheye lens distortion, which can relieve the pressure of network transmission broadband and backend storage and improve the efficiency of monitoring operations.

A good panoramic camera must have a high resolution image sensor. Due to the wide monitoring range of the panoramic camera, the information volume of the image sensor must be very large. Unlike the general camera, it only needs to process a part of the screen in the monitoring scene. Therefore, whether the resolution of the image sensor is high or low is also the key to affecting the image clarity after the monitoring image is enlarged.

Virtual PTZ can be used to zoom in and zoom out of stored images. In the field of security monitoring, PTZ controls the pan/tilt/left/right rotation and the lens change focus. It is used to automatically or manually track and lock the target and track the target in the monitoring range. The virtual PTZ used by the panoramic camera has a similar concept to that of the pan-tilt, except that the actual mechanized rotation does not have to be performed like a real pan-tilt, but the similar effect is achieved by zooming the image, and thus the monitoring system can be greatly increased. The service life makes it easier for the monitoring personnel to operate and reduce maintenance costs.
