We may have ever seen the PTZ Camera/ PTZ Camera Outdoor/ PTZ Webcam HD/ PTZ Camera Night Owl/ PTZ Network Camera/ Pan Tilt Zoom Outdoor Network Camera in our daily life, but can't recognize it or don't know its name. Today let me introduce the PTZ Camera for you. PTZ Camera refers to the camera with the PTZ, so what is the PTZ?
The classification of the PTZ
In conclusion, I hope that the introduction about the PTZ can help you better understand the PTZ Camera.

What is the PTZ?
PTZ, the abbreviation of Pan/ Tilt/ Zoom, is the supporting equipment for installing and fixing cameras. PTZ can be divided into two types: the Fixed PTZ and the Electric PTZ. The Fixed PTZ is suitable for the situations where the surveillance range is not large. After the camera is installed on the fixed pan/tilt, the horizontal and tilt angles of the camera can be adjusted. After reaching the best working posture, just lock the adjustment mechanism. Motorized PTZ is suitable for scanning and monitoring a large area, it can expand the surveillance range of the camera. The high-speed attitude of the electric pan/tilt is realized by two executive motors, and the motors receive signals from the controller to operate and position accurately. Under the action of the control signal, the camera on the PTZ can automatically scan the surveillance area, and can also track the surveillance object under the control of the staff on duty in the surveillance center.
According to the characteristics of the PTZ's rotation, the PTZ can be divided into the horizontal rotating PTZ that can only rotate left and right, and the all-round PTZ that can rotate not only left and right but also up and down. Generally speaking, the horizontal rotation angle is 0°~350°, and the vertical rotation angle is +90°. The horizontal rotation speed of the constant-speed PTZ is generally 3°~10°/s, and the vertical speed is about 4°/s. The horizontal rotation speed of the variable-speed PTZ is generally 0°~32°/s, and the vertical rotation speed is about 0°~16°/s. In some high-speed camera systems, the horizontal rotation speed of the PTZ is as high as 480°/s or more, and the vertical rotation speed is more than 120°/s.
In fact, the PTZ, composed of two AC/DC motors, is an installation platform, which can move horizontally and vertically. The PTZ applied to the monitoring system can be controlled the direction of rotation and movement remotely through the control system, which is different from the PTZ( just a tripod, which can only be adjusted by hand) in the photographic equipment.
In conclusion, I hope that the introduction about the PTZ can help you better understand the PTZ Camera.
The "longevity" of leeks is longer
The cultivation of leeks is too dense and too shallow. Although they can quickly achieve high yields, they are also prone to excessive leeks because the leeks produce too fast. As a result, the yield and quality of leeks rapidly decline after planting for about three years, and they have to be renewed. If the planting density and depth are reasonable, the production time of leeks can be extended to 4 to 5 years. Determining a good plant spacing When planting leeks, planting 30 to 40 plants with a row spacing of about 28 cm and a length of 2 meters is most suitable. This density can not only extend the production time of leeks, and push the renewal period of leeks, but also make leeks grow thick and of good quality. Definite depth of planting The deeper the colonization of leeks, the weaker the ability to deliver, the slower the root topping, the shallower the colonization, the stronger ability to deliver leeks, and the quicker rooting, will soon result in the roots of leeks growing above the ground, affecting the leeks. Planting years. In general, the depth of colonization of leeks is 5 to 6 cm, which not only affects the plant's tillering, but also prevents the plant from jumping too fast and leads to the problem of too short a planting period. The renewal period of crickets is extended to 5 years.
