I’ve recently been looking into a lost-cost solution for a wireless director’s monitor and/or AC focus monitor, without the expense and commitment of a high-end / high-price wireless transmitter-reciever set. I do most of my shooting on a Canon C300 that provides both HD-SDI and HDMI outputs, so my HDMI port sits mostly un-used. I don’t need the wireless feed to travel via HD-SDI which adds to the cost of such wireless devices. I found a great nofilmschool.com article that sent me in the right direction.
The Nyrius ARIES Pro is a low-cost wireless HDMI set marketed as a way to send a wireless feed from your laptop to your TV. The ARIES Pro sends a 1080p signal up to 160′ with no signal delay. When adapted properly, this is the perfect solution to our dilemma.
The problem outlined in the nofilmschool.com article by cinematographer Ryan Walters is how to power the receiver:
“The receiver has to be powered via the included AC adapter. Which really isn’t that big of a deal, as the monitor has to be plugged in anyway. So, for now, I don’t have a completely wireless solution…”
If you’re like me and want a wireless, hands-free operating monitor, this won’t cut it.
The solution I uncovered is actually a simple one.
NOTE: This only works with the SmallHD DP6 field monitor. This is because it is the only monitor that has a USB port that functions as both an input for updating firmware, but also can act as a power source. Inside the menus, this USB port can actually provide a constant 5V power output that can power the Nyrius ARIES Pro receiver.
The microUSB port on the receiver only functions as a HID Remote Control function and does not allow a USB power input like the transmitter. This leaves the 3.5mm 5V DC port as the only power terminal. I started thinking of a way to get a USB cable with that 3.5mm plug on the other end. As luck would have it, buried deep in my drawer of cables, I came across a USB power cable for a semi-old LaCie portable hard drive. The power end just so happened to have the same 3.5mm connector. (Link to purchase the cable below if you don’t have one lying around…)
Here’s how I have my setup configured:
On the camera side, I plugged the Nyrius ARIES Pro transmitter directly into the HDMI port of the camera (The ARIES Pro also comes with an HDMI right-angle adapter). I used a Paralinx USB Regulator Cable to convert a P-Tap port on my Anton Bauer battery to female USB. Then using the supplied USB to Micro USB cable, I can power the transmitter. If you do not power your camera with an external battery like Anton Bauer or V-Mount, you can use a portable USB battery supply like the Aluratek.
On the wireless monitor, I mounted the SmallHD DP6 to a short 15mm rod with Redrock Handgrips on either side. This makes handholding the unit super easy and comfortable. I then attached the Nyrius ARIES Pro receiver to a clamp via the handy 1/4″-20 thread on the back. Using the LaCie USB Power-Sharing cable, plug the receiver into the SmallHD USB port for power. Just add an HDMI cable from the receiver to the monitor, and you’re all set!
REQUIRED EQUIPMENT LIST:
I hope this wireless option provides you with an easy and affordable way to get rid of those tethered cables and open up a whole new world of operating. Until next time..
