Teradek Cube 255

This is a fantastic device that turns up to 4 WiFi devices (smart phones, tablets, laptops, etc) into wireless monitors. The Cube uses Wi-Fi to connect to an existing Wi-Fi network, then uses the network to wirelessly stream to any Wi-Fi device and then live monitor with it. You can even stream it online and view it remotely if you want to. I use it on most of my sets, I usually give an iPad to the director, have the producer connect to it with their laptop, have the boom op use an arm band with their phone to monitor frame and if we're shooting 2 cameras and I'm also oping I'll attach my phone to A-cam with the B-cam feed so I can monitor both cameras simultaneously. If you're using multiple cameras you can also get multiple cubes and monitor up to 4 cameras on a quad display on all of your devices. And the delay is very minimal , usually 1/3 of a second.

This is the HDMI version, if your camera does not have HDMI I have a SDI to HDMI converter I can include if you need it or you can rent my SmallHD 502 monitor which has built in SDI/HDMI cross conversion.

For power it can connect to p-tap, bullet, or AC. If you need a battery solution I have a couple of different options so we can make it work with whatever configuration you need.
