Nimbus WiMi6200 HD-SDI Wireless Video Transmitter Leistung und Fähigkeiten
12 Jahre alt. Geräte und Preise können sich seitdem geändert haben.
Was die Diskussion ergab
- Das WiMi6200 kann HD 1080p-Video bis zu 3000 Fuß Sichtlinie mit Standard 6dBi-Antennen mit 2-Frame-Latenz übertragen, wenn es auf einer dedizierten Empfängereinheit empfangen wird.
- Das System kann mehrere Gebäudewände durchdringen, wobei die Übertragung durch 4+ Hauswände im Produktionsbetrieb bestätigt wird.
- WiFi-Streaming auf Laptops und mobile Geräte funktioniert in kürzeren Bereichen um 200 Fuß mit 4-6 Latenzrahmen im Vergleich zum dedizierten Empfänger.
- Latency changes based on bitrate, with 12 Mbps producing 2 frames of delay while 25 Mbps produces 4 frames of delay.
- The transmitter uses 802.11n WiFi on the 5GHz band with 50mW transmitting power and 3x MIMO antenna technology.
- The device can transmit to multiple receivers simultaneously in multicast mode or to a single receiver with WiFi streaming disabled.
- The system performed reliably through RF-dense environments and on location commercial productions with consistent transmission through building walls.
- Picture quality from the transmitter was noted as superior to some competing wireless video systems for focus pulling and video village monitoring.
- The 2 frame latency can cause noticeable lip-sync issues between audio and video in scenarios where synchronized monitoring is critical.
- Power connector is 4-pin mini-XLR with no option for alternative connectors like Lemo at the time of discussion.
- Audio delay can be managed using external audio delay units to compensate for video latency.
Hängt ab von
- FCC approval status was pending at the time of discussion with confirmation expected Monday.
- Latency may be problematic for focus pullers and director monitoring in sync-critical situations.
- Dedicated receiver required to achieve the full 3000 foot range and 2 frame latency specifications.
- WiFi streaming option has significant latency increase to 4-6 frames compared to dedicated receiver path.
- The system uses open WiFi transmission which raises potential security concerns about unauthorized viewing.
- European regulatory approval was not addressed in the thread.
