Look at the cost performance of mobile phone signal jammers from four aspects

When choosing a mobile phone signal jammer, the cost-effectiveness is one of our more important points. So how do you see the cost-effectiveness of a cell phone signal jammer? Let's learn about it with the editor of the dojammer mobile phone signal jammer manufacturer:

Factor 1: Effective shielding

The so-called effective shielding refers to whether there are blind spots or missing spots in the shielding effect. Near some prisons, there may be transmitting base stations with strong mobile phone signals. In order to achieve a good shielding effect, a lot of materials and energy will be spent correspondingly, and the cost will correspondingly increase substantially. Therefore, the better the shielding effect, the higher the cost. In actual use, the shielding requirements are generally higher, and there are some missing or blind spots. Offenders may seize this loophole, so that the mobile phone can be used in the originally prescribed shielding area, and the original intention of shielding the mobile phone cannot be achieved.

Factor two: no failure time

If the original stipulation that the failure-free service life is 1 year and the failure-free service reaches 3 years in actual use, the cost performance will be tripled.

If the original stipulation that the failure-free service life is 1 year, it will often fail in less than half a year in actual use. Although it is a free warranty, the risk is immeasurable, personnel resources are wasted, and the corresponding price-performance ratio is greatly reduced.

Factor 3: External interference

If external interference is not considered, it is relatively easy to simply shield, as long as the shielding power is increased. But it is necessary to ensure that the shielding area has no blind areas and no leakage points. The power intensity in the shielding area is relatively high. If there is a little leakage, the external interference will be great. This requires full consideration and technical control during shielding design to achieve precise and efficient shielding without external interference.

Factor 4: Cost

The cost should follow the shielding requirements and budget. You can't blindly choose cheap products, and you can't think that the expensive is good. In the actual choice, word of mouth is very important. It is necessary to conduct a field inspection of past cases, test the shielding effect, and then make a selection.
