The most rock solid transmitter I have ever seen

The Wevi Cam-Wave is a IEEE 802.11a device, so it's around 5 GHZ.

 

 

802.11a is 2.4 GHZ that's why 2.4Gig cordless phones and microwave ovens screw them up

 

Actually no, 802.11b and g work in the 2.4 GHz range, Anders was right 802.11a works in around the 5 GHz mark.

 

It's why 802.11b & g are compatible with each other and 802.11a won't work with either. 802.11a isn't affected by phones and microwaves, but also has a smaller range because of the higher frequency.

Hi

 

We have one in the hire kit at MK-V.

 

The range is probably about 100 meters line of site. About 40-50meters through 2 soundstage walls.

 

The Unit is in the 5Ghz range. It also has the usefull feature of letting you know on the transmitter when it's lost contact with the reciever.

 

When audio is transmitted through the sender it delays the audio too so it stays in sync. If the unit is being used for film work we hire it with the "Behringer Shark DSP" which delays the audio from the sound bods to the director etc so they recieve them both at the same time.

 

It aslo has the usefull function of going between in V-Lock mount and the battery if you wish.

 

Regards

Ant

5.8 ghz Wifi 802.1 a. it's about an inch and a half taller and about a half inch wider than a standard battery mounting plate. Definitely larger than a modulus by a lot. But it fits between the battery and the mount (v-mt), and draws power and passes power through.

Hi All,

 

Pardon my ignorance in all this. I have been holding out from getting the Canatrans - I need something in addition to my Modulus 3000.

 

So this Wevi-cam is worth it? The picture is that awesome? Just have to deal with this 1/2 second sync delay is that it? That is obviously a large problem. Would be totally unacceptable to most Directors I work with. Mike Nichols I'm currently with would have an absolute fit! And I would be out on my ear!

 

Is it as simple as Ants "Behringer Shark DSP" unit?? We hand this magic 'audio delay box' to the Sound cart and they put it in line at the audio feed out going to the video cart, is that it? Are there other magic Audio delay boxes that achieve this?

 

Does this magic delay box need to be powered? Dimensions? How much does it cost? It seems to me to be fairly critical in order to take advantage of the rock steadi picture of this WEVI CAM.

 

How do you control how much to delay the Audio in order to match the delay in the video? Pardon if some of this has been covered,.... long day

 

Is this thing IDX specific? Will it piggy back to Anton Bauer plate in same fashion?

 

Thanks fellas,

 

Will

Will, the Canatrans is spectacular. Use it with this antenna:

It's a great system!

Hi Ramon,

 

I go to that site and it just puts me at the home page index. Which antenna do you mean exactly? You mean that one pictured on the index page?? circular thing with a tubular thing coming off the circular thing? Looks like a pretty hi profile thing to me- Hope its smaller than palm of my hand!

 

Canatrans doesn't inspire masses of confidence. For all the times I've been on set when it does work well, there are just as many times it has been totally garbage. Maybe your antenna is the trick.

 

Anyone with experience with Canatrans and the Wevi thingy? Ramon, sorry, assuming you haven't played w/ this Wevi thing...

 

Thanks,

 

Will

Will, havent used the Wevi but did read the spec sheet. Personally I'm still using my 1.2 GHZ analog link.

 

Any audio delay line box should be ok, just set it to 380 milliseconds and the audio will be delayed the approx. 10 frames of the MPEG-2 codec. The Behringer is about $80. It's 56 mm x 88 mm x 130 mm, and comes with an external PSU. Should be possible to adapt it to a AB mount though...

Hey Will.

I have the canatrans for almost a year now. To be honest, at first i was a little disapointed. I use it with the transvideo hercules reciever, and it was not that solid. But it was better than the modulus, and the costumerservice of the modulus, well we all know that.

 

2 Month ago, i bought a small sharkfin antenna, and boy that made a difference. The picture is rock solid most of the time. I have learned to take the time to find a clean channel, find out what output power to use, and where to place the antenna. If you do that, 99% of the time it rocks. I'll rather work this way than with 1/2 second delay. Most of the directors i work with , wont be happy with that.

 

Regards Job

I found the wevi thing to be a bit big and cumbersome for film jobs. If the picture does drop out you have absolutely nothing! freeze frame... at least with UHF you can still see where the eyeline is.

 

At present it only comes with v-locks.

 

I would be tempted if I did a lot of run and gun TV work where I could not look after wireless and it fits nicely onto the back of very lightweight cameras or I was shooting really high end comercials all the time and the clients/post boys demanded a perfect picture.

 

Useless for promo s.

 

The thing is it only costs 2800 dollars and it works well so you may as well have it in your arsenal for when you need it but it s definately not an all encompassing solution.

That's not too much of a problem, most cameras nowadays are v-lock anyway, and somebody will always have a PAG to v-lock or A/B to v-lock adaptor plate anyway, and its easy enough to get hold of a v-lock battery kit from somewhere if you needed it. I've found these links work well for corporate and live stuff, but as you say not much use for any other applications. Although 'the-boxx' does do a generic version that is just the box, that can be mounted anywhere with a bit of velcro and powered with cables and fed with a BNC, easy enough. I'll just stick with my Teletest 2.4 Ghz for now, it does a good enough job!

Thought I'd pitch in my 2 cents since I just tested the WEVI...

 

PROS

-------

+ Truly rock solid picture. As good as hard-wired.

 

CONS

-------

+ Big and chunky

+ Distance not as great as my old Coherent - not even close, in fact (I went out my apartment, turned left, and down the walkway). Distance about as far as a Modulus, difference being when you lose the WEVI signal, it's gone - period, whereas a broadcast transmitter will fade in and out

+ V-lock mount. Someone mentioned getting a PAG or AB adapter but the thought of adding ANYTHING to this already hefty unit is not appealing.

+ Significant delay, though unless the DP or director is standing in front of the action, this seems mostly irrelevant
