Q. So I am building an underwater ROV and my team needs a camera to mount onto our robot. It needs to be water proof, but if you have to buy a separate box it might be okay. It should be wireless, but we could run a Ethernet cable if we have to. And of course it needs to be able to live stream onto a laptop on the surface of the water.
I have looked into using a Go Pro, but I am unsure of what model to get and Go Pros seem a little pricey, so cheaper options may be better.
Does anyone have any ideas on what i can use? If i use a Go Pro i need to know which model is best, but I would like cheaper options if they exist. Thank You

A. Underwater wifi is relatively new and not "readily" available.

at least, not from regular stores. If you are depending on the GoPro wireless connectivity to do what you want, I would bet against it - at least for now. That means some sort of tethered version. As far as I know, there is no wired, direct, "streaming" capability that will do what you want. Remember, the GoPro is a camera/camcorder and designed to capture video locally to a memory card.
Wireless communication is one thing - wireless video is a whole different animal (bandwidth issues in the aquatic/marine environment).
And if you are using a robotic craft, I am guessing the ROV is going to be more than 100 feet away which means if on land, would be on the edge of wifi's reach - underwater, even more so. The GoPros included waterproof housing is rated to only 40 meters (~130 feet).
A camera-only (no local recording), with a cable, solution may be a more do-able option. Since we don't know how deep the camera needs to go and we don't know how far away the camera will be (it could be 5 feet deep but 300 feet away) it is impossible to actually make a recommendation. This shallow, but far away is different than 300 feet deep because of the pressure exerted at that depth.
Your solution may be as simple as

which is even more than the GoPro. This is an underwater wired camera designed to do what you want. Similar to a security camera, it has a single cable that includes connections for power and the video feed. The power is supplied on the computer side of the cable - the camera does not carry local power. The camera does not store video locally, but sends the video over the wire to an analog/digital converter. This can be a standalone box like those from Blackmagic Design, Roxio, Elgato, Thompson/Grass Valley/Canopus or a card fitted to the computer.
And keep in mind that at about 40ft-50ft and deeper, you will likely need to add light. Underwater lighting can be pricey...

Sony digital camera( DSC-TX30/B)....this camera good or no? please tell........?
Q.
A. Here is a review

Within the category of immersible compact cameras, its image quality is probably among the best in the studio test, although that is not a category with spectacularly great image quality. In the real world comparison tests it seems to have fallen a bit below the competition.

It is the lightest and most compact within that class. However, it is not a very easy camera to handle for actual diving.
With any compact camera you should use a wriststrap, and all the more so when handling these water resistant cameras in the water. with no floatation attached, they will sink.
For diving the Canon D20 has an advantage with the best ergonomics. Image quality is good for its class with least noise reduction smudging or highlight clipping. The Nikon AW110 is a very good overall performer for its class in image quality and has least chromatic aberration. The Olympus TG-2 gains an advantage in low light with its f2 lens. For video with real time sound, its sound gets terrible when immersed in water.

The Pentax WG-3 also has an f2 lens, but its images were rather dull in this test
http://www.youtube.com/watch?v=Jnxn_Ng-1U8
The Panasonic TS5 seems to produce some nice images, and it has the best video options, but its autofocus is sluggish.
A peculiar thing about the Nikon AW110 is that they package it with a neckstrap and advise against using a neckstrap in the water for safety reasons. An aftermarket wriststrap should be purchased for it.
