Elliot's blip

So Elliot wants to feature tonight
His question is why can we see the blue light on the Sky handset but not if you just look at it.
Try it will your TV controls, press a button and see if you see the signal then look through the camera !
Home alone tonight, Elliot at Michaels, Peter, Ben and Max at the Everton match, just checked they won, thanks goodness happy people will be coming home
