What are the advantages and disadvantages of the built-in test room signal jammer compared with the external test room signal jammer :
Of course, in terms of environmental protection, energy saving and heat removal, the built-in cannot be compared with the external one. From the external structure, the built-in shield is integrated with wireless, power supply and radiator in an external plastic case, which is more beautiful and easy to use from the appearance design, and does not require cumbersome link antennas. , Plugging and unplugging the power supply, etc., in some colleges, examination rooms, conference halls, and confidential venues where the flow of personnel is easy to manage or in areas where they are often moved.
In terms of structure, the external shield is made of thick pure aluminum alloy through oxidation spray painting and other processing techniques to integrate the circuit board and the chassis and fully use its own shell to achieve a very good heat dissipation effect, because the antenna uses an external Connection, power supply is also not conducive to long-term mobile use, complicated operation, inconvenient installation, but its own advantages are also particularly strong, the external heat dissipation effect is stronger, combined with the above advantages, the external shield is more suitable for college classrooms and student apartments. , Churches, military, prisons, detention centers and other fixed sites that need to be used for 365 days of continuous work and stable use.
The factors that should be considered in the selection of the signal jammer equipment model of the examination room:
The choice of signal jammer in the examination room is good for oneself. Don't trust any big brands. Price is not a major factor either. Whether the signal shielding device in the examination room is qualified can be verified in terms of raw materials and processing technology used. There are some basic requirements for the selection of signal jammers, such as whether there is a formal company registration, whether there is a trademark registration, etc., you can ask the manufacturer to show the mobile phone signal jammer debugging photos, and the internal structure photos are the basic standards for distinguishing a mobile phone signal jammer. .
