The Short Range HDMI over Cat5 Extender is an ideal solution for an application where the HDMI source is placed at a distance from the display that is greater than the average 50 foot length limitation of a HDMI cable. Extending a HDMI signal over Cat5 cables allows for utilization of existing Cat5 cable infrastructure for a cost-effective and reliable in-wall installation. With our HDMI over Cat5e Extender, a display can be placed across the room, in another room, or on another floor while the source remains in a convenient, secure location. This solution is HDCP™ compatible. Note: This solution includes one power adapter which must be connected to the receiver for proper operation. The transmitter is designed to draw power from the HDMI source device. Some HDMI source devices are unable to output the power required for the transmitter to function which results in no image being displayed. In those instances, an HDMI Voltage Inserter (42223 or 42236) may be required. Cat6 cables may also be used for a maximum extension of 130 feet.
