Not even 100% sure if the camera was pointed on the seed or not. But yes I agree, maybe if I get too much Kopfkino I will create a new wallet. But if they were really watching it would have been gone already I think.
You should stop thinking about it buddy too much, it will cause huge spikes of stress time after time. If you think that they might have seen your wallet's seed phrase then try to check out your wallet address in a block explorer, and if you see no new transactions then I'm pretty sure you're 100% safe. But, still if you fear then just go for the new wallet. It's far better to take a step then worrying.
