Why do you install a large number of shields and the shielding effect is not good?
Most of the signal jammer devices are used in prisons, schools and factories. The scope is large and the shielding area is large, but the budget is still very limited. So the question is how to achieve the shielding effect with a limited budget, which means you How can you use less shielding devices and still achieve the desired shielding effect? At this time, many businesses will let you increase your budget or give you cheap shielding devices. You seem to save money now, but in fact You are wasting money, why? Listen to me telling you slowly:
The knowledge point is here, so quickly write it down in a small notebook and use it as shoddy.
First of all, the shielding device is divided into industrial grade (7*24 hours long-term power-on) and commercial grade (3-5 hours power-on). Some places need 7*24 hours long-term power-on of the shielding device. If you buy the cheap one, you think you If you take advantage of it, the merchant will give you a commercial grade as an industrial grade. If you use it for more than half a year, it will break. Then you will find the manufacturer to repair it. If you buy from the manufacturer, you will not be charged for repair Expenses, but the courier costs you send back to the manufacturer are also borne by you. At this time, if you want to change to another store, you will feel that you have just bought it, and it is troublesome and wasteful to maintain it all the time. Is it very annoying and want to curse? So it's better to buy a good one at the beginning. It's the same as buying a mobile phone. A cheap mobile phone either has a low configuration or it breaks after half a year. It's better to just buy a good one.
Insufficient business experience makes it impossible to achieve the blocking effect you want
The shielding device in many places is subject to man-made damage, such as prisons and student dormitories. If the power of the shielding device you buy is not enough, you can only put it on the surface, but it will often be destroyed if you put it in an invisible In some places, the signal shielding will be incomplete due to insufficient power of the shielding device, causing unnecessary losses. So the placement position is especially important. This requires a lot of case experience to know. Many businesses on the market have no such experience.
So, a lot of experience + good products = the cost you save.
