The WP-1C Wireless HDMI Transmitter Receiver System with dual Canon LP-E6 type battery plates from Marshall Electronics features a range of up to 100' line-of-sight with less than 1 millisecond of latency, and will broadcast resolutions up to 1080p60. The system supports HDMI 1.3 and is HDCP compliant, meaning it can pass copy-protected sources such as commercial Blu-ray discs. The WP-1 features a camera-mountable transmitter which includes a shoe mount as well as a belt clip, if you prefer to wear it. The belt clip is especially useful for DSLRs and small camcorders that lack a cold shoe or where the transmitter might get in the way. There are also a 1/4"-20 socket so you can mount the transmitter or receiver with a separately available articulated arm or swivel shoe.
Both the transmitter and receiver can either be battery-powered or powered using AC. A single AC adapter comes with the system that can be used on either the transmitter or the receiver. There is also a PowerTap cable, available separately, if you want to power either component, or both, from an external 12VDC source, such as a professional video battery system.
