In the cold winter, for the farmers, in addition to the human body to do a good job of cold and warmth, the crops must also be cold and antifreeze to prevent the adverse effects of low temperature frost. Agricultural experts give a few tips:
For different crops and different growth periods, it is necessary to strengthen the management of fertilizer and water in the field, promote crop growth and improve cold resistance.
For open crops, timely clearing the ditches for drainage, reducing the groundwater level can effectively prevent freezing damage, and at the same time combined with clearing ditch, the soil will be cultivated in the roots of the crops to play the role of grass warming and seedling protection.
For the greenhouse facilities, measures such as covering straw curtains, non-woven fabrics, shade nets or multi-layer coverings can be adopted for heat preservation, and ventilation at the same time can be used. The general guards of spraying trees can maintain the temperature of the plants themselves and prevent the occurrence of diseases. Spray a new high-fat film on the vegetable seedbed and nursery field to form a polymer film and cover it with a small arch shed film or straw.

PTZ: In the security monitoring application, it is the abbreviation of Pan/Tilt/Zoom, representing the pan tilt omnidirectional (up and down, left and right) movement, lens zoom and zoom control.
Fuvision's autonomous automatic PTZ intelligent tracking enables the camera to automatically PTZ drive its own PTZ and zoom lens, and automatically controls the PTZ Camera to rotate the PTZ in all directions and zoom the lens. It also conducts visual oriented automatic tracking for the locked moving target to ensure that the tracking target continues to appear in the center of the lens with a close-up image, so that the guards can see the information more clearly, It can also be used for obtaining evidence afterwards. The automatic PTZ tracking module makes up for the narrow field of vision of fixed camera monitoring, which is an essential function of a perfect security monitoring system.
The intelligent vision PTZ automatic tracking and monitoring system has the target analysis function, and is equipped with a high-resolution camera, a large magnification optical zoom lens and a high speed PTZ, which can automatically capture suspicious targets quickly and accurately. By setting the preset position intelligent vision PTZ automatic tracking monitoring system, the preset position scanning, automatic cruise and other functions can be realized, and many special requirements of intelligent monitoring can also be realized. In addition, the intelligent vision PTZ automatic tracking and monitoring system also has the advantages of beautiful appearance and strong concealment, so it is very suitable for public security intelligent monitoring applications in airports, squares, rail transit, villas, government administrative units, military regions, museums and other types of places.
