A short while back Amimon made available a Wireless HD Video Kit primarily targeted for Drone use called the Connex. The Connex kit could stream Full 1080p HD Video up to 60fps at a distance of 3300ft with incredibly low latency. The kit, not originally designed for video shooters was quickly modified by Camera Motion Research and has since been a popular affordable choice for those looking to send wireless HD video.
Keep in mind the Connex Mini does not stream audio, but the main stand out features for the Connex Mini are it's compact size, stream long distances up to 1600 ft, almost zero latency, and more importantly the ability Multicast up to 4 receivers (if you're looking to expand your kit in the future). These combined features are normally only found on more expensive systems.
So what other applications would need Wireless HD Video? Besides drone use, or on set sending feed to a director's monitor, this can be setup on a gimbal or Steadicam while someone else pulls focus remotely (low latency is important on this one). It can also be used on a Cable Cam setup or to send wireless video back to a Multicam Switcher during live events. There's multiple reasons why you may one day require wireless video, and the Connex Mini is a good option to keep in your radar. You can get more information about the Connex Mini and custom accessories available from Camera Motion Research at CAMOTIONLLC.com (here).
At some point in time you may find yourself on a project that will require you to send a feed to a remote monitor for others to view. Perhaps you have a client that needs to provide input about your camera settings, lens choice, framing, or movement. Or maybe you have an assistant to help with a wireless follow focus. And when your camera can't be tethered with a cable, eventually you may find a need for a kit to transmit video wirelessly. So here's a look at the CAME-TV 100m Wireless HD Video Kit.
There are systems designed for the home that you can use for a DIY solution, but often this means shorter range and lots of latency. Home kits are usually bulkier, will require you to be innovative about your battery solutions, and you'll need to find a way to mount it to your camera and monitor. Another reason you have to be careful about DIY kits is compatibility with frame rates. The Panasonic GH3 outputs a weird interlaced signal, the Canon 5DM3 and Sony cameras when set to 24p actually output 23.98. The GH4 on the other hand can output 24p, 23.98, and then you have cameras that can output 59.94p. There are a good number of Monitors that can't display these frame rates, and wireless HD Video kits are the same.
If these are reasons that would deter you from DIY home kits, the CAME-TV 100m Wireless Video Kit is clean and simple, easy to operate, minimal parts, and works great for transmitting up to 300 feet+ (depending on conditions). I have tested 1080/24p Cinema mode from the GH4 as well as NTSC 23.98, and 59.94 with no issues.
The Nyrius Aries Pro is just one of many consumer grade kits available to stream wireless hd video via HDMI. I have a few articles posted on this blog going back a few years ago, but with the recent popularity of Gimbal Stabilizers, these streaming video tools can really aid your production. Here's a great demo from Rod Guajardo [thanks Rod] on how they use the Nyrius Aries Pro kits.
Though many of the wireless kits on the market may look similar, the internal components differ slightly offering faster processors and more channels for less interference, less video lag, and greater range. Still if you're just planning to monitor from a camera without having to be tied down by wires, the Nyrius Aries Pro is an excellent kit (found here).

[Update] It should be noted that these kits have no mounting options so you'll have to be creative. They also require power over USB which are very common these days, but only certain batteries with a high mAH rating should be used. You can see a list of compatible USB batteries and also some creative mounts used by the CMR Radian kits (found here).

Since the announcement of Teradek's Cube which streams HD Video wirelessly to pretty much any device you can think of including the iPhone and iPad, people have been trying to find their own solutions to stream video to a remote monitor. Teradek offers many modular pieces with their products along with many more features than to just stream video, but that all comes to several thousands of dollars. Not to mention with all the abilities it can provide, can also provide more configurations to worry about. Some articles surfaced the web regarding a few 'options' that might help people achieve streaming HD video to a monitor without breaking the bank. These are also very dumbed down solutions that do exactly what they say they do - stream HD Video. The two popular HD Wireless Streaming solutions are made from Asus and Brite-View. For Asus they have an item called the 'WiCast', and for Brite-View they offer an 'Air SyncHD' and 'HDelight'. From other reviews the units functioned pretty much equally and I picked up the Asus solely on the size and look of the units. The Asus WiCast is extremely lightweight, feels almost hollow, and all plastic. The lightweight is actually an advantage if I plan to mount this onto the hotshoe of my camera, or somewhere on a shoulder rig, but also means I shouldn't be throwing it around. With new EVF's (electronic view finders) with HDMI pass throughs making their way into the marketplace, this would be a great solution to use an EVF while streaming video out wirelessly for someone else to monitor, or even pull focus.

The Asus WiCast comes with both a transmitter and receiver that creates it's own little ad-hoc network to each other. The time it takes to sync together is fairly quick, possibly under 10 seconds once they are both powered on. The video streams are fast, and I notice no latency or dropped frames. I haven't tested range yet, and i'll re-post when that's up. They both come with an AC adapter (exact same adapter for each) that supplies 5 volts to the unit. This low voltage and low amperage requirement means a DIY battery pack, or an already existing battery pack to power them up would be easy to find. Most people aren't ready for streaming video to a remote monitor wirelessly, but by knowing how you can achieve these same results for several times less than high end solutions, maybe this will open up some creative possibilities with your video. A few things that come to mind is to stream the GoPro HD Hero video, or even extending the reach of a monitor on a long Video Crane.
