QVideo is pleased be introducing the new Nimbus HD-SDI Transmitter/Receiver the WiMi6200, which can transmit HD 1080p video;

 

- up to 3000ft LOS (with standard antennas- 6dbi)

- passes through 4+ house walls

- Multicast

- 2 frame latency

- streams video to laptops and mobile devices

 

The Nimbus WiMi6200 has been tested and working for the past 6 months in working environments and it has preformed beyond expectations. Please check out our Test video's, Operator Test, and Blog.

Nice price, amazing capability, almost too good to be true... so dare I ask: FCC approval? 

 

I only ask because I see you're a Canadian company, and was curious if the device is permitted for use in the USA?

Nimbus submitted for FCC approval Nov of 2013, I have not had a update recently, I will have answer for Monday.  The transmitter uses 3 x MIMO Antenna Technology, using the 802.11n Wi-Fi, 5GHz band, with a transmitting power at 50mw. I have never experienced the Nimbus creating any intererance problems at any time on set or anywhere when testing during the last 6 months.

 

For watching video on my laptop I log onto the WiMi6200 Tx wireless network like I would for any wireless network, then using the VLC video program I enter the Nimbus IP adress and up comes the camera picture. I get a range of about 200ft with my laptop in a open studio and I have tested the signal to pass through 2 house walls. There is more delay with the video streaming, approx 4 to 6 frames.

 

Using the WiMi6200 Receiver allows receiption of up to 3000ft at 2 frame delay with HD-SDI output as well as LAN out. So it can transmit to the receiver and stream video to laptops, LAN, etc. at the same time, its pretty cool.

 

Cheers

Quinn

Can you supply the TX / RX with Lemo power connectors as opposed to the mini XLR which it looks like it comes with?

You are correct the WiMi6200 is 4pin MiniXLR. Right there is no option for Lemo, but I will suggest/ask Nimbus if there are any plans in the future and have an answer for Monday.

Everything looks good but...2 frames latency.

Yes one twelfth of a second delay, could make it difficult in some situations. Focus pullers might struggle with it but then again the picture quality of the 6200 used too find focus is far superior than some other popular Tx's. The Nimbus has been used for steadycam work with no difficulties. Another issue that can arrise is audio sIippage that can be rectified with an audio delayer (remember Arri D21). I have been using the 6200 for 6 months and have not run into any issues caused by it's latency.

 

But there are so many more sinarieos which people just want to see a picture (ie. car to car, video village). So the Nimbus Tx sends video farther with greater penitration and better clairity at better price than any comparible Tx. The Nimbus being adaptable for more situations, and at a lower price can get more rentals. I have payed off my 6200 in 6 months and have bought a second one so I now have two sets.

Have you tested the latency at 25MBs vs 20 or 12? I know I have played around with some consumer HDMI H2.64 wireless systems and they have a way to reduce latency by lowering the compression (with little visible image degradation, especially for video village situations.)

And I'm not sure what the studios positions are going to be on open transmission via wifi. Imagine fans sitting outside the studio watching the movie as it's being made...

Yes the Mbps does make a diffence in delay 25Mpbs is 4 frames and 12Mbps is 2 frames. And I have observed the same as you that their is very little visible image degradation between 25 to12 and the 12Mbps image is a considerably better quality image than a lot of Boxx's I have worked with. I am going to be asking Nimbus about replacing the 20Mbps to 10 or even 8Mbps.

I finally got the 6200 car to car test video's uploaded. The tests were shot downtown Vancouver  and Stanley Park which is just by downtown. The results were pretty good. We got a good idea of distance and how far around corners the 6200 was capable of going. It also demonstrates the ability of the Nimbus to work in an environment with a lot of RF going on.
Video's can be viewed at:

Can the wifi be disabled and limit the transmission to only the receiver unit?

Yes Wifi Streaming can be disabled and only transmitted to one Receiver or to multiple Receivers in Multicast Mode.

Hello everyone,

 

can I ask if somebody tried to test this in europe? The range and all the videos I have seen looks absolutely perfect to be true for the price, but if it is, I want to have it!...

 

Thanks

 

Jan

Hi Jan,

I used this on a 4 day Jaguar car commercial in the UK, our video playback guy had a set.

Working in and around the Jaguar car plant, including their hot and cold rooms it transmitted through several walls back to video village never dropping out once.

I don't think it can be faulted for a consistent transmission however the delay is quite noticeable once it has left the camera gone through the Q-Take and back to the monitors. The director was complaining about the lag as he was listening to Nicolas Hoult 4-5 frames earlier than the image. I think this system is ideal for any MOS, car to car or any situations where sound isn't an issue.

The Ikan WK1 and new Teradek Beam have the same specs so I suspect they all share the same guts. However the Nimbus and Ikan are way cheaper!
