When installing security Outdoor Camera, you should first choose the monitoring host. Do you want to add a monitoring card to your computer, or do you want to use an embedded hard disk recorder as your monitoring host. The computer monitoring card is more suitable for places that are familiar with computer installation, have professional personnel on duty, and have more functional requirements. Its overall investment is relatively low. Since the monitoring card is installed in the computer, the computer needs to be started 24 hours a day; As for the latter, it does not require professional knowledge, nor does it need to be on duty, and it is relatively simple to operate.

The principle of the laboratory dry granulator is to directly press the dry powder into thin slices and then pulverize and granulate. Therefore, the yield in the dry granulation is high and low. Firstly, it has a direct relationship with the material formulation, and the yield of the material with good compressibility is required. The high point; there is a great relationship with the strength of the pressed piece and the cutter structure and the speed of the granulation. The strength of the tablet is related to the size of the pressure and the feeding speed. The feeding process is also a pre-pressing process. And the degassing process, if the air in the material is exhausted as much as possible, and the material has a pre-stay zone, so that the pressed piece will not be intermittent, so that in other cases, the yield is relatively Will improve.
Laboratory dry granulation granulation machine tool structure will directly affect the yield of granules, pulverized pieces if the pressure in the granulation cabinets frequency, this will also reduce the yield, the present embodiment uses granulation reference to foreign company Roller The material is quickly rolled out from the screen to improve the yield, and the slower the pulverization speed, the higher the yield of the particles, and the slower the point without blocking the mesh.
Laboratory dry granulator during granulation discoloration Materials: Usually after dry granulation of the material through the original color will differ powder, since the surface area is larger than the surface area of the powder particles, the reflected light rays are different, the other After the pressed particles increase the bulk density of the original powder, the color of the particles will also deepen. Generally, the greater the pressure on the pressure roller, the deeper the color will become, and the pressure on the pressure roller is not only the pressure on the pressure roller. The pressure of the oil pump is also related to the feed speed and the tableting speed. Under the condition of constant pressure and tableting speed, the faster the feeding speed, the greater the pressure acting between the pressure rollers, and vice versa, the same at the pressure and feed speed. In a certain case, the slower the tableting speed, the greater the pressure acting between the pressure rollers, and vice versa. Therefore, when using the dry granulator, the user should select a good pressure and speed according to the actual conditions of the material, so as to improve the yield of the product on the basis of ensuring the performance of the product.
To install security monitoring equipment, it is necessary to determine how many cameras are installed, and the quality and monitoring range of the cameras are affected. It is preferred to determine how many cameras are used for monitoring, and then determine the camera lens monitoring range according to how many cameras are available. Therefore, the distance from the camera to the monitoring point and the monitoring area must be clear. The infrared supply network recommends using the camera of 480 TV line, because it is more in line with that definition.
When installing security monitoring equipment, the third consideration is whether the camera has night vision function. If the monitoring is installed in a dark place, it is necessary to consider using a camera with infrared night vision function.
The security monitoring equipment can be installed via wired or wireless transmission. Although the cost of wireless network is relatively high, it can save a lot of installation trouble and make the monitoring site more beautiful. However, the installation of wireless network monitoring equipment should take into account the environmental problems of security sites. Cement building materials will shorten the wireless transmission distance, and metal building materials may complete the shielding of wireless signals. The infrared transmitter and infrared receiver should be far away from other appliances to avoid interference. Because the price of wireless network is almost twice that of wired transmission monitoring equipment, I suggest using wired transmission installation.
On site monitoring and network monitoring When determining the installation of the monitoring system, you should consider whether you need network functions. That is, if you need to monitor and control the monitoring site on the Internet at any time, you need to select a monitoring host with network functions. Avoid no network transmission function after installation.
A complete security monitoring equipment should at least have three parts: surveillance camera, PTZ and decoder. The following are their installation methods:
