In this year's Heilongjiang some production areas of Heilongjiang Province continue to reduce the production of their own homes, with an average reduction of around 30%. After the new production, the north and the south merchants will come to the place of origin to purchase, which will drive up the price increase, which will increase by around 3 yuan year-on-year. About 21 yuan.
After the production of new bulbica and the drug market, the rate of production of the new bulbifera fell rapidly, and the rate of decline was relatively large. The pace of movement was slow, and many businesses were waiting to see it. They did not dare to absorb it. The drug market price of the drug market had dropped to about 40 yuan, and fresh goods moved well.
After the production of new horns and new markets, the sales volume slowed down and there were few large cargo transactions. As the price dropped gradually, the pharmaceutical market fell to around 9-11 yuan. In the short-term, look at the market.
The price of Caoguo’s early rise was too fast and the heat was too high. As the new production deepened, the prices declined gradually, and there was a large backlog of large cargoes. Recently, there were pharmaceutical factories coming to the market to purchase, and the sales momentum improved, the prices stabilized and there was a slight rebound. , The drug market is about 36-40 yuan.

We may have ever heard of the Bullet Fixed Focus Camera/ Fixed Focus Bullet Camera HD/ Bullet Fixed Focus Journal Camera/ Fixed Focus Bullet Camera IR/ Fixed Focus Bullet Surveillance Cameras/ Fixed Focus Analog Bullet Cameras, so what is the Bullet Fixed Focus Camera? We know that the Bullet refers to the camera shape, so what about the Fixed Focus? Actually, the Fixed Focus refers to a type of the camera lens. Today let me introduce the camera lens for you.
The camera lens is the key equipment of the video system. The lens' quality (index) directly affects the overall index of the camera. The lens is equivalent to the lens of the human eye. As you know, if there is no lens, the human eye cannot see anything. That is to say, if there is no lens, then the output image of the camera will just be white without any clear image output; which is consistent with the principle of our home cameras.
Actually, there are many classifications for the camera lens. Today please let me introduce one classification for you---the classification according to the structure.
1. The fixed focus lens with the fixed aperture
The lens has only one focus adjustment ring that can be manually adjusted. Rotating the ring left and right can make the image on the CCD target surface clearest. There is no aperture adjustment ring, so the aperture cannot be adjusted, and the luminous flux entering the lens cannot be changed by changing the lens factors, but can only be adjusted by changing the illuminance of the shooting site. The structure is simple and the price is cheap.
2. The fixed focus lens with the manual iris
Compared with fixed focus lens with the fixed aperture, the fixed focus lens with the manual iris has an extra aperture adjustment ring. The aperture range is generally from F1.2 or F1.4 to fully closed, which can easily adapt to the illuminance of the shooting site, and the aperture adjustment is done manually. The illuminance is uniform and the price is cheap.
3. The fixed focus lens with the automatic iris
Compared with the fixed focus lens with the manual iris, the fixed focus lens with the automatic iris has an extra gear-driven micro motor on the iris adjustment ring, and a 3 or 4-core shielded wire is drawn from the drive circuit, then connected to the camera's automatic iris interface seat. When the luminous flux entering the lens changes, the charge generated by the CCD target surface of the camera changes accordingly, thenthe video signal level changes, and a control signal will be generated and transmitted to the automatic iris lens, so that the motor in the lens can perform the corresponding rotation to complete the task of resizing.
4.The electric zoom lens with the automatic iris
Compared with the fixed focus lens with the automatic iris, the electric zoom lens with the automatic iris two extra micro motors. One motor is connected with the zoom ring of the lens, and can control the focal length of the lens when it rotates; the other motor is connected with the focus ring of the lens, and it can complete the focus of the lens When it rotates with control from the former motor. However, due to the addition of two motors and an increase in the number of lens groups, the size of the lens has also increased accordingly.
All in all, it would be helpful to know about the camera lens if you want to know more about the Bullet Fixed Focus Camera and the whole video monitoring field.
