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
