Burglars are not deterred by cameras or alarm systems, especially in the age of face masks. They know they will only be in the house for 5 mins or less and face masks make it harder to identify them.
The small handful of valuables we have are either stored in an obscure enough place that the thief would have to devote longer than 5 minutes to finding it, or so esoteric that I doubt a random burglar would recognize its value.
