Soluzione di sorveglianza COFDM per la trasmissione video wireless

In the field of surveillance and security, affidabile trasmissione video senza fili is essential. Traditional Wi-Fi or analog links often fail in a lungo raggio O non-linea di vista (NLOS) ambienti. This is where COFDM surveillance solutions stand out, fornendo stabile, crittografato, e trasmissione video a bassa latenza over challenging terrains.

Recentemente, many customers have shown interest in implementing COFDM wireless technology for vehicle-mounted cameras, 360° surveillance systems, and control room monitoring. Let’s explore the key requirements e il hidden needs that often come with deploying a COFDM surveillance solution.

Hidden Needs for COFDM Surveillance Systems

While customers usually list the basics, many critical requirements are not mentioned explicitly. UN professional COFDM surveillance solution should consider the following:

1. Qualità video & Latenza

• Required resolution: HD, Full-HD, or 4K.
• Real-time response with bassa latenza (<100ms).
• Efficient compression (H.265/H.264) for better bandwidth usage.

2. Mobility & Stability

• Support for high-speed vehicle movement (Polizia Stradale, militare, emergenza).
• Doppler-resistant COFDM modulation for uninterrupted reception.

3. Energia & Ruggedization

• Vehicle-compatible power supply (DC 12V/24V).
• Design robusto: impermeabile, antipolvere, shock-resistant.

4. Control Room Integration

• Multiple output formats: HDMI, SDI, flusso IP (RTSP/UDP).
• Option for multi-channel reception to monitor several vehicles simultaneously.

5. Sicurezza & crittografia

• AES-128/256 encryption for secure video feeds.
• Authentication to prevent interception of surveillance data.

6. Scalabilità

• Expansion to cover multiple vehicles and personnel.
• COFDM Mesh Networking or relay mode for extended range.

7. Conformità normativa

• Legal operation within the AS923-1 frequency band.
• Certification and licensing support for local regulations.

8. Facilità di distribuzione

• Plug-and-play setup with existing security infrastructure.
• Portable handheld receivers for security staff in the field.
• Software integration with NVR systems or cloud-based monitoring.
