camera in nest box

[barquar]

I have a blue tit roost in a nest box. I want to put a camera in it, if i do it in the day while its not in there, will it notice the camera that i put in and scare it away.I dont want to put it off roosting in the box. Should i leave well alone or is it possible to put my camera in without scaring it away.

Put camera in nest box and as not put Blue tit off from roosting in it. Comes to roost at 4-10pm and goes out at 7-30 am in the morning.He gets himself in a fluffed up round ball head tucked in by his wing. great to see him in the box.

Is there anything in the box? does it tuck itself into the sides of the box or stay in the centre?
