Internet Remote Control System Waterproof Prison High Power Signal Jammer
Model: U-J300JW
The U-J300JW is specifically engineered for prisons and other sensitive facilities including military bases, government compounds, airports, stadiums, executive offices, board meetings, conferences, seminars, libraries, cinemas, religious places, public transport, concert halls, restaurants, and educational institutions. This advanced jamming system features remote control capabilities via internet, radio communication, or wired connection.
How It Works
The Mobile Signal Jammer transmits powerful radio signals to disrupt communications between mobile devices and cellular base stations. It exclusively targets cellular communications within the designated regulated zone without interfering with other communication systems. When activated, all idle phones display "NO SERVICE" and incoming calls are blocked as if the phone is turned off. Service is automatically restored when the jammer is deactivated.
Key Features & Advantages
- Adjustable jamming frequency and output power via LAN or internet remote control
- Three communication methods available for flexible deployment
- Real-time equipment monitoring and comprehensive logging
- Multi-level login permission system with varying access authorities
- Integrated LCD display showing all module working status
- Building plan upload capability for easy system navigation
- Email and sound alarm notifications for real-time system monitoring
- Supports up to 6 different frequency bands
- Outdoor waterproof metal alloy casing with high resistance to dust, water, and corrosion
- Smart cooling system with heat sink and fans for 24/7/365 continuous operation
- Total output power up to 400 watts
System Overview
This high-power jammer effectively addresses the problem of illegal cell phone usage in prisons and government facilities. Our prison solutions utilize RF jammers to prevent smuggled phones from making calls. Systems can be configured to block large areas within buildings or arranged in fixed patterns to radiate RF interference, defeating mobile network access attempts.
Technical Advantages
- VSWR protection prevents system damage from antenna disconnection
- Stable, cost-effective performance
- Individual channel control with adjustable output power
- DDS technology for precise frequency and power adjustment
- IP65 waterproof rating
- Remote monitoring via IP network
- RJ45 remote control interface
Applications
Prisons, military installations, government facilities, oil and gas storage facilities, churches, theatres, libraries, museums, courts, border patrol and drug enforcement operations, customs, mosques, and other sensitive locations.
