Solicitação Original do Cliente
1 – We would need a one way with the camera transferring from shore to the dredge
2 – Camera would be on the shore at the end of the discharge pipe and the receiver and monitor would be on the dredge so can see what is happening on shore.
3 – Anexamos um pdf com algumas fotos que mostram a ‘configuração’. There is a mast located on shore as well. Esteja ciente de que não há conexão com a Internet disponível na draga.
Compreendendo a necessidade do cliente
The client’s project involves real-time video monitoring between a dredge vessel and the shoreline, where the camera is placed onshore e o receiver and display are mounted on the dredge. The key challenges are:
- Long transmission distance over water
- No internet connection available (so cellular or IP-based systems are not possible)
- Stable one-way HD video link from shore to vessel
- Ar livre, harsh marine environment (requiring waterproof, anti-salt, and shockproof housing)
This setup requires a robusto, point-to-point digital wireless transmission system that can deliver claro, delay-free HDMI video even under sem linha de visão (NLOS) or sea surface reflection conditions.
