Essential nest box fix

Hi all, well I am in a bit of a predicament, I recently moved one of our camera equipped boxes after is showed very little sign of activity.
Almost as soon as I’d finished fixing the box, a Blue Tit went straight in. Great stuff! The activity progressed and we’ve had one roosting for about a week, although it’s not shown for the last two days. We are having regular day visitors to that box now too.

Now, typically the camera has developed a fault, the supplier has asked for it to be returned for repair or replacement in my own time, so no issue there.
Because of the activity, I didn’t want to leave it too long, so bought another camera, and my plan is, tonight providing there are no roosters, I will take the box down, swap the cameras out without fuss, and replace the box asap under darkness.

Is this a plan, and might I get away with it?

When the camera is fixed or replaced, I’ll quickly put out another box in another location.

Any help or opinions appreciated.

Thanks.
Steve
