<< < (2/3) > >>

michaelb:
many thanks for all the tips and advice regarding getting it off the ground, bit of a minefield as whatever we come up with bound to be criticised, but hay ho,someone has to do it .. My Grandson has suggested gopro cameras connected WiFi to monitors via an App to a smart phone to control and zoom  hopeful my be able to get him to help to talk in language I understand.  What have I let my self in for.

Going go pro wireless system sounds attractive and in theory gives a great flexible system. BUT.... it is only wireless because it runs on batteries so be sure about the time you want to use it for and battery life / remembering to charge them up etc...

Also, I think you need to consider the image resolution. I have been to numerous turning clubs (doing demos) where cheap cameras were used and the image then displayed on a large screen via projector or on large TV sets. If any of the components puts a limit on the pixel resolution, then you will get a grainy image which is not very helpful to the audience.
Your standard 42" TV nowadays has a resolution of 3840 x 2160 pixels, and ideally your cameras and all other kit in between should be able to handle this, otherwise there will be fuzziness. Most cheap dashcams or camcorders won't support this, so watch out.

We use an almost identical system at Herts and Beds Woodturners (Hemel Hempstead) but using an AKASO EK7000 action camera (instead of the more expensive GOPRO).  The essential point here is that the camera can be operated independently of the battery simply by plugging in the battery re-charging cable (runs from a transformer and is also used to re-charge the battery when it is in the camera).  So you don't have to worry about the battery running out of charge in the middle of a demo. 

The resolution of the AKASO is 3840 x 2160.

Hope this helps?

Make sure you get the permission of the demonstrators before you start filming!
