Preventing Low-Altitude Intrusions: Building a High-Security Prison Defense System
In recent years, incidents of drones illegally flying over prison areas have occurred frequently, creating the following serious security threats:
- Delivery of contraband (drugs, mobile phones, tools, etc.)
- Aerial surveillance and reconnaissance
- Disruption of internal prison order
- Support for prison breaks and other high-risk activities
To address these challenges, it is essential to establish an efficient and scalable “Prison Anti-Drone Defense System” to ensure a clean airspace and the information security of closed facilities.
I. Common Drone Intrusion Methods and Characteristics
| Type | Features |
|---|---|
| GPS Navigation Type | Fixed route delivery, highly concealed |
| Manual Remote Control Type | Real-time control, accurate targeting, but limited by control range |
| Image Transmission Reconnaissance Type | Real-time video transmission for reconnaissance or monitoring activities |
II. Components of a Prison Anti-Drone System
A complete anti-drone system should include the following modules:
1. Detection Module
- Multi-source fusion using radar, RF spectrum monitoring, and optical identification
- Capable of identifying flight paths, drone models, and frequency bands
2. Signal Jamming Module
- Utilizes broadband RF power amplification modules combined with high-gain directional antennas
- Covers common frequency bands (900M / 1.2G / 1.5G / 2.4G / 5.8G)
- Disrupts drone control, image transmission, and GPS navigation, forcing drones to return or crash
3. Command & Control Module
- Integrates video surveillance, access control, and alarms
- Provides automated alerts and historical record tracking
