Filming a passion project in Peru. Unsure what sort of documentation I need for customs.

I'm shortly travelling to Peru to film wildlife in the Amazon Rainforest.

I'm aware I don't need a permit as this isn't commercial, but do I need an ATA carnet or something else?

I'm travelling with roughly £6000 of equipment:
- sony a7siii + a7iii
- dji mini 4 pro
- small lighting setup
- small mic + boom setup
- dji rs3 gimbal
- a few tripods / stands

ChatGPT tells me just to walk straight through nothing to declare, but naturally I'm a little cautious of getting gear seized. there's a lot of mixed advice.

It's worht noting I filmed in the same region of Peru last year, but with considerably less equipment. Would appreciate anyones advice here.
