Description

DCH-5400EC 4-Channel HD Encoder​

​Product Overview​

The DCH-5400EC is a 4-channel H.265/H.264 HD encoder supporting ​4× HD/SD-SDI signal inputs. It accepts multiple signal sources (e.g., satellite receivers, CCTV cameras, broadcast servers) and encodes input signals via ​H.265/H.264 compression. Renowned for reliability and high performance, it is widely deployed in hotels, schools, apartments, clubs, live streaming, and security surveillance systems

.

​Core Features​

      .

    • 1080I inputs are ​output-converted to 1080P​ to avoid interlacing compatibility issues.
  2. ​Audio Flexibility:
    • Dual sampling rates (44.1kHz/48kHz) support both music production and broadcast standards

      .

  3. ​Network Optimization:
    • ​SRT protocol​ enhances anti-packet-loss capability for public network transmission

      .

  4. ​Deployment:
    • ​19-inch rack-mountable design​ (483mm width) with redundant power for critical environment
