Chúng tôi sẽ đền bù thích hợp hoặc gửi linh kiện mới / sản phẩm mới.

Sản phẩm của bạn hoạt động như thế nào?

Hệ thống phá sóng của chúng tôi hoạt động bằng cách phát ra tín hiệu nhiễu RF mạnh và có định hướng, làm gián đoạn tín hiệu liên lạc (như tín hiệu điều khiển drone hoặc tín hiệu di động).
Đối với drone, nhiễu RF làm mất GPS hoặc liên kết điều khiển từ xa, khiến drone lơ lửng, quay về hoặc hạ cánh tự động.

Tôi có thể sử dụng sản phẩm này tại quốc gia của tôi không?

Chúng tôi giao hàng toàn cầu.
Tuy nhiên, quy định về thiết bị phá sóng khác nhau tùy quốc gia/khu vực.
Vui lòng kiểm tra luật pháp địa phương trước khi mua hoặc sử dụng.
Chúng tôi là nhà sản xuất, không phải tư vấn pháp lý, nên không thể đảm bảo tính hợp pháp ở mọi nơi.

Nên chọn thiết bị phá sóng cầm tay hay cố định?

Thiết bị cầm tay:

  • Nhỏ gọn, cắm là dùng

  • Phù hợp sử dụng tạm thời, di chuyển, hoặc bảo vệ cá nhân

Thiết bị cố định:

  • Hoạt động liên tục 24/7

  • Công suất mạnh hơn, phạm vi rộng hơn

  • Phù hợp phòng họp, cơ quan nhà nước, hoặc trạm bảo vệ cố định

Nếu bạn chưa chắc loại nào phù hợp, hãy liên hệ, đội ngũ kỹ thuật sẽ tư vấn giải pháp tốt nhất.

Làm sao biết drone đang theo dõi bạn?

Các dấu hiệu có thể bao gồm:

  • Tiếng vo ve bất thường

  • Drone xuất hiện gần khu vực của bạn

  • Camera hoặc đèn của drone hướng về phía bạn

Những gì có thể vô hiệu hóa drone?

Các thiết bị có thể vô hiệu hóa drone gồm:

  • Súng chống drone

  • Thiết bị bắn lưới

  • Laser công suất cao

  • Bộ phá sóng điện tử

Làm sao để xử lý một chiếc drone làm phiền?

Hãy sử dụng các biện pháp hợp pháp, ví dụ:

  • Báo cơ quan chức năng

  • Dùng hệ thống chống drone (nếu luật cho phép)

  • Sử dụng vật cản che chắn

Điều gì xảy ra khi bạn phá sóng drone?

Khi bị phá sóng, drone có thể mất kết nối điều khiển, hoạt động lỗi hoặc tự quay về điểm xuất phát.

How Does the Drone Jammer Work?

Drone jammers work by transmitting targeted radio frequency (RF) signals to disrupt the communication link between a drone and its remote controller.

When the control signal is blocked, the drone will typically trigger its built-in safety protocol such as return-to-home, hovering, or landing.

Some advanced systems can also interfere with GPS or other navigation signals, causing the drone to lose positioning capability and preventing it from continuing its flight mission.

What Technologies Are Used in Anti-Drone Systems?

Modern anti-drone systems combine several RF countermeasure technologies to neutralize unauthorized drones.

Communication Signal Interference

The system blocks the wireless communication channel between the drone and the operator, interrupting command and data transmission.

Navigation Signal Disruption

By suppressing or interfering with satellite positioning signals such as GPS or BeiDou, the drone loses its navigation capability.

Protocol-Based Control Interference

Some systems can simulate or override control signals, forcing drones to land or return to their starting point.
