Are there any cameras which require a PIN before deleting photos?

Question

This would protect you from mischievous kids (or malicious brats, as the case may be).

Answer

No, there are not.

I have heard of rather expensive write-once memory cards, if you are truly serious about preventing deletion.

Also expensive but at least reusable is an Eye-Fi card which sends photos to a WiFi access-point as they are shot. That way, even if they are deleted from the card, the photos will be on a computer somewhere.
