the toiletry bag itself does not weigh more than 300 grams. I'm thinking of telling them that the box arrived empty, that the toiletry bag was missing, my main question is if they have cctv in their warehouses

First and foremost, what's the "precise" weight of the bag?

If It's too heavy for the missing Item method, then the cameras are not part of the equation- you'd need to opt for another method that does not have any association with CCTV footage. That's If cameras are In place to begin with.

The toiletry pouch weight 190gr
