## Long description

The 4K HDMI via IP Extender Set (DS-55122) is a video distribution system that transmits 4K HDMI signals over network cabling. It includes a transceiver unit capable of extending 4K (3840x2160p, 30 Hz) video up to 120 m over a CAT6 cable in a point-to-point setup. When used with additional receiver units (DS-55123) and a network switch, the system can deliver video to up to 253 displays via an existing IP network. The unit supports HDCP 1.4 and common Ethernet cabling types for flexible installation.
Advantages
The system supports both direct CAT6 point-to-point extension and distribution over an existing local network, allowing signal extension to virtually unlimited distance via IP. It supports 4K resolution at 30 Hz and a maximum HDMI bandwidth of 10.2 Gbit/s. The extender is compatible with CAT5, CAT5e, CAT6 and CAT7 cables and includes a unidirectional IR interface for remote control of the source device.
