In 2019, a prison installed our high-power signal shielding system.

The prison covers a large area. A total of 10 sets of SMa-818K200+ high-power signal jammers are installed on the walls around the prison. The directional antenna is used to face the inside of the prison, which can prevent all outdoor and indoor signal interference in the prison. and shielding.

When the high-power signal jammer system is installed, the installation of several directional antennas supporting it needs to be firmly installed. The installation bracket of the directional antenna in this case is specially customized.

This set of signal jammer system is far apart and widely distributed, so the wireless remote control system configured with the system will greatly facilitate the customer's control and management of the first signal jammer terminal.
