DCH-5300EC H.265/H.264 HD Live Encoder
Product Overview
The DCH-5300EC is a high-definition live encoder supporting UHD/HD HDMI and HD SDI signal input/output. It enables simultaneous HDMI and SDI encoding/decoding, compatible with multiple signal sources such as satellite receivers, CCTV cameras, Blu-ray players, and set-top boxes. Equipped with H.265/H.264 encoding capabilities, it decodes local IP streams into H.264/H.265 formats for remote signal monitoring. Renowned for reliability and high performance, it is widely deployed in hotels, schools, apartments, clubs, and security surveillance systems

Key Technical Notes
Interface Differences:
HDMI: Consumer-grade interface for short-distance transmission (≤15m).
SDI: Professional-grade locking interface (BNC coaxial) with strong anti-interference, supporting transmission over hundreds of meters
.
Intelligent Encoding:
ROI: Allocates higher bitrates to key areas to enhance visual quality.
AVBR: Dynamically adjusts bitrates to balance quality and bandwidth, ideal for unstable networks
.
Resolution Limits: 2160P resolution requires HDMI input; data port is prioritized for management access to ensure bandwidth stability.
