Rozwiązanie dozorowe COFDM do bezprzewodowej transmisji wideo

In the field of surveillance and security, niezawodny bezprzewodowa transmisja wideo is essential. Traditional Wi-Fi or analog links often fail in dalekiego zasięgu lub brak zasięgu wzroku (NLOS) środowiska. This is where COFDM surveillance solutions stand out, że stabilny, encrypted, i transmisję wideo o niskim opóźnieniu over challenging terrains.

Ostatnio, many customers have shown interest in implementing COFDM wireless technology Do vehicle-mounted cameras, 360° surveillance systems, and control room monitoring. Let’s explore the key requirements i 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. ZA professional COFDM surveillance solution should consider the following:

1. Jakość wideo & Utajenie

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

2. Mobility & Stabilność

• Support for high-speed vehicle movement (Policja, wojskowy, nagły wypadek).
• Doppler-resistant COFDM modulation for uninterrupted reception.

3. Moc & Wzmocnienie

• Vehicle-compatible power supply (DC 12V/24V).
• Rugged design: wodoodporny, pyłoszczelny, shock-resistant.

4. Control Room Integration

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

5. Bezpieczeństwo & Szyfrowanie

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

6. Skalowalność

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

7. Zgodność z przepisami
