Your child's daycare center may have security cameras at every turn, but that's no guarantee they're monitored -- or even turned on. Exterior doors may not be monitored, either, which means just any ol' stranger can wander in at will. Security lapses are not something you want in a daycare center, that's for sure.
On the flip side, daycare centers that make gaining entry like an exercise at Fort Knox may have more than your child's safety in mind. Not only are they keeping bad guys at bay, but parents can't come inside unannounced. And that doesn't exactly instill confidence, either.
