Overview

Successful Cases
Our Company


No Phones. No Smuggling. No Escape. No Risk.

By deploying cell phone blockers, correctional facilities can instantly cut off calls, texts, and data connections—eliminating contraband phones, unauthorized communication, and smuggling attempts, while ensuring a controlled, confidential, and secure environment.

Features

Support all cellular bands

The blocker can support all the 2G/3G/4G/5G cellular bands of different mobile network operators and Wi-Fi frequency bands all in one device. 

Plug and play

The blocker may be used in various scenarios and places, where the cellular frequencies may be different. To make the service fulfillment easy, the blocker is designed to adapt to different radio environment automatically. It supports plug and play, without the necessity of parameter setting.  

No interference to base stations

It only blocks the reception of on-site mobile devices and does not affect surrounding base stations.

7-50M Omnidirectional Blocking

The K-14-5G device uses an omnidirectional antenna array, significantly increasing the blocking distance. It blocks various types of mobile phone signals within a range of 7-50 meters, completely interrupting all communications.

Remote and local management

The signal blocker could be centrally managed through the internet and standard TCP/IP protocol or configured locally with a PC.

Precautions:

1. Factors affecting the actual shielding range include signal field strength, base station distance, mobile phone format, obstacles, installation height, installation specifications, etc.
2. It is normal for the host to heat up after working for a long time. If the temperature is too high, please turn off the power and contact your local dealer
3. The normal installation height is 1.8m～2.5m, try to choose the place where there is no obstacle between the target shielding area. The wall-mounted installation requires the antenna to be vertically upward. When using on a desktop, the antenna can be folded 90 degrees and then vertically upward. There should be no AC power lines or other audio and video lines within 0.2 meters of the antenna.
4. In order to avoid possible interference with some electronic equipment, please try to keep 1~2 meters above the following common equipment: audio, wireless microphone, radio, computer, TV, Wi-Fi router, Rcied, etc.
