It's a web version, so not indicative of actual performance.

True but wouldn't you think Sony would attempt to put their best demo footage on their website where they're trying to sell the camera?

There's a lot more artifacting on any of their demos (at least the 6 I looked at) than the GoPro main page demo.

I just watched the video demo's and was underimpressed. http://store.sony.co...Sony_Action_Cam The extra 19mbps makes a big difference.

Too bad because I sort of wanted one.

Hello all,

I am not into video at all but, for a job at my company I have the need of using a big crane with a demolition tool underwater (for a reinforced concrete caisson removal). I am searching for solutions on how to attach a camera and housing to the tool, feed it electrically (it has to be working some 12 hours straight...), and have a signal cord to the crane´s cabin (where I would install a screen for the driver) some 100-150 meters long. I think that even a WA HD GO PRO would do but I don´t know how to feed it electrically. I also thought of a DSLR with Seacam´s remote vision (or a normal screen) but I face the same electrical feed problem... Is there any idea that you would suggest?

Thank you very much!

I think you'd need something a whole magnitude better than a GoPro - something that can take a beating based on the shock it will be subjected to.  Is the concrete 100M deep? It will be dark and under a lot of pressure also so I don't think any consumer grade housing will stand up to that for very long.  Plus if you mount the camera close enough so it's actually useful for the operator it will likely get hit by debris occasionally. You're also going to need a lot of light. Once you start tearing up concrete u/w it's going to create a tremendous amount of silt and clouds of dust/debris.

Maybe something like this: http://rosys.com/oce...c/mantis-ocean/


Or something from here: http://www.sea-viewd...rinecameras.htm You might also consider something 3D so the operator has a better perspective on what he's doing. http://www.sea-viewd...vdsp3dhires.htm

google remote underwater video camera for more options.

Maybe talk to someone who does similar work to see what they recommend. You should be talking to commercial salvors or oil-rig inspectors - not u/w videographers whose only concern is keeping their camera dry.

Who are you renting (I assume) the demolition rig from? Don't they already have something they're using on it? Their operator must need to see what he's doing somehow...
