What should I consider when choosing a cell phone jammer in a prison? Let me introduce it to you.
One: effective shielding
The so-called effective shielding refers to whether the shielding effectiveness has blind spots and leaks. In some prisons, there may be transmitting communication base stations with strong mobile phone signals. In order to achieve effective shielding effects, it will take a very large amount of raw materials and energy, and the cost will correspondingly increase. Therefore, the better the shielding effect, the higher the cost. In actual use, the shielding standard in the prison area is usually higher, with a little leakage and blind area, and illegal manpower may catch this loophole. The mobile phone can be used in the shielded area, but the purpose of shielding the mobile phone cannot be achieved.
Two: No failure time
If the mobile phone signal jammer can be used for one year without failure, but in fact it can be u sed for three years without failure, the cost performance is tripled. If the product has a trouble-free service life of one year, in fact, problems often occur within 6 months of use. Although it is free of charge, the hidden dangers are immeasurable, human resources are wasted, and the corresponding cost-effectiveness is affected.
Three: External influence
If you don't consider the external influence, just shielding will be relatively simple, just increase the shielding output power. However, it is necessary to ensure that the shielding area has no blind spots and leakage points. The output power in the shielding area is very strong. If there is a little leakage, the external shielding effect will be very large. This needs to be considered in the shielding design process, and technically controlled, to achieve accurate and efficient shielding, without external shielding affecting the outside world.
Four: Expenses
Expenses should follow the shielding needs and cost budgets. You can’t rush to choose cheap products, and you can’t think that the expensive ones are good. In fact, user evaluation is very important in the selection. Try to block the effectiveness, and then make a selection.
Through the understanding of the above elements, I believe that everyone understands that when choosing a mobile phone signal jammer, it is appropriate to choose a cost-effective one.
