Security Wireless Monitoring Engineering Frequently Asked Questions

Our current security monitoring project often ignores its maintenance and maintenance only when it sees the effect. What are the problems that need to be paid attention to when installing wireless monitoring? Let's look at it:
First, the power supply is incorrectly caused by equipment failure, the power supply is incorrect. There are several possibilities: the power supply line or the power supply voltage is incorrect, the power is not enough (or the wire diameter of a certain power supply line is not enough, the voltage is too large, etc.), and the power supply The transmission line of the system has a short circuit, an open circuit, an instantaneous overvoltage, and the like. In particular, damage to equipment due to power supply errors or transient overvoltages has occurred recently. Therefore, in the system debugging, before power supply, we must carefully check and check carefully, and should not be taken lightly.
Second, because some devices (such as cameras with three variable lenses and pan/tilt) have many links, if the processing is not good, especially if the line connected to the device is not handled well, there will be open circuit, short circuit, and line. Poor insulation, incorrect wiring, etc. cause damage to equipment and performance degradation. In this case, the analysis should be carried out in a calm manner based on the fault phenomenon, and it is judged that the fault phenomenon occurs on the several lines due to the problem of which lines are connected. This will narrow the scope of the problem. It is particularly worth noting that the camera with the pan/tilt is very common due to the all-round movement, which leads to the disconnection and breakage of the connection. Therefore, the connection between the equipment and various lines that pay special attention to this situation should meet the requirements for long-term operation.
Third, the quality of the equipment or components themselves. In theory, quality problems can occur with various equipment and components. However, from the experience point of view, the quality problems of the products themselves are mostly on the decoder, electric cloud platform, transmission components and other equipment. It is worth pointing out that some equipments may not have the problem of being unusable in quality as a whole, but from some technical indicators, they fail to reach the indicators given in the product manual. Therefore, the necessary sampling tests must be performed on the selected products. When it is a product quality problem, it is a good idea to replace the product and not disassemble it. In addition to this, the most common problems caused by improper adjustment of the equipment. For example, the adjustment of the rear intercept of the camera is a very detailed and precise work. If not carefully adjusted, there will be problems such as poor focus or defocusing during various operations of the three variable lenses. In addition, whether the position of some switches and adjustment knobs on the camera is correct, whether it meets the technical requirements of the system, whether the decoder code switch or other adjustable parts are set correctly will directly affect the normal use of the device itself or affect the normal performance of the entire system. .

Microchannel Heat Exchanger

MiroChannel Heat Exchanger is normally used in auto mobile , household and commercial AC system. In refrigeration area is intial stage, so we mainly focus on designing condenser & evaporator for this market. Especially for the evaporator , we can produce the evaporator whose joint with the electro-heater together, which better enhance defrosting efficiency.
