There are times when you need to send video back to a monitor or switch, but because most DSLR and Mirrorless cameras only offer HDMI out, you are limited to how far you can position the camera. To exceed the limits of HDMI, this HDMI to SDI Converter will allow you to use SDI cables for longer distances.

Wireless kits with HDMI input, like the Radian Pro Kit from Camera Motion Research allow a camera operator to move freely, but they will still have limitations and can be prone to drop outs if the feed has to be sent through walls, the receiver is too far, or if there is interference. Running an SDI cable with the Wireless HDMI Receiver attached at the end can help you minimize the distance your between your wireless system while still having the entire camera system over 100 feet away.

So if you're looking for a way to get your cameras moved further from where you need to send your feed, these HDMI to SDI (not SDI to HDMI) converters are probably the cheapest you can find. It does require power, or in my case, i'm using an adjustable voltage Tekkeon battery pack. I've also tested this converter with a BlackMagic Pocket Cinema Camera, and it works if you're looking to send a long video feed from that camera. Check it out via Amazon (click here).
