I feel guilty using debug mode to buy these and yet I would like to buy them so now they are in the catalog.
The cameras are in Electronics -> Misc. They cost the same as they do buying them from a merchant.
And as you can see here, each sarcophagus is priced. Imported from an Al Simharan museum, or something like that. They are found under Comfort -> Beds, or the Bed icon in the room sort. Be warned that since it is still the sarcophagus of kings, the sarcophagus of kings WILL turn a sim who sleeps in it for too long into a mummy. It is not advised to use it as a bed. ;D
