4 factors affecting the price/performance ratio of prison mobile phone jammer system
Factor 1: Effective shielding
The so-called effective shielding refers to whether there are blind spots or missing spots in the shielding effect. In 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 cost will increase accordingly. In actual use, the shielding requirements in prison areas are generally higher, with a little missing or blind spots, and offenders may seize this loophole, making it possible to use mobile phones in the originally prescribed shielding area, failing to achieve the original intention of shielding mobile phones.
Factor two: no failure time
If the original stipulation signal jammer that the failure-free service life is 1 year and the failure-free service reaches 3 years in actual use, the price/performance ratio has tripled.
If the original stipulation that the trouble-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. However, 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 large. 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 more important to investigate the past cases on the spot, test the shielding effect, and then make a selection.
