720P 高畫質 DTV CAM
50–950 MHz / 1200–1350 MHz
06 · DTV 攝影機系列
特色
- 01 輕鬆升級高畫質
— 可沿用既有的同軸纜線佈線，對纜線與接頭無任何特殊要求。 DVB-T 訊號極為強韌，即使是劣化老舊的纜線，也能完美傳送高畫質訊號。 - 02 操作簡單直覺 — 不需設定網路 IP，也不必接桌上型或筆記型電腦。就像用電視機或機上盒看電視節目一樣簡單。
- 03 長距離傳輸 — 只需一條 3C2V/RG59 纜線即可輕鬆傳送高畫質影像達至少 500 公尺，中途無需加裝任何轉發器。用於無線應用時，在 0dBm RF 輻射功率下視距傳輸距離可達 50~100 公尺，在 20 dBm 下可達數公里。實際距離取決於天線設計與接收機品質。
- 04 串接佈線（匯流排拓撲） — 多台設定為不同頻道的 DTV CAM 可共用同一條纜線，大幅降低佈線的成本與工時。
- 05 即時協定與低延遲 — 在 QEF（準無誤碼）條件下不會掉幀，且傳輸延遲低。
