It was a careful emergency precaution.
After the first time Dick was kidnapped the complete and utter panic Bruce went through caused premature white hairs. Since Alfred refused to let him place a tracker in Dick (“Wait until he’s older Master Bruce! For heaven’s sake he’s only eight!”), Bruce settled for the next best thing: cameras. There were cameras set up everyone in the Manor: the bathroom, Dick’s bedroom, the garden, the kitchen (that reminded Bruce he needed erase last night’s footage of him stealing a cookie), the gym, basically every room possible in the house.
Just last night he finished the mobile one that will discreetly track Dick’s movement everywhere. He called it the cute cam.
Bruce sat back and congratulated himself. On the screen showed a sleeping Dick cuddle a bat plushie. “You’ve out done yourself this Bruce. This was your best idea yet.”
"MASTER BRUCE!"
Shit.
