I'm currently working with FFI (Fauna & Flora International) in São Tomé and Príncipe, and a bunch of 'problem' camera traps from the field site have been sent over to FFI's UK office (in Cambridge). The camera traps are not functioning, and there doesn't seem to be anything the matter with them externally, which indicates that it might perhaps be an internal issue.
The camera traps are all Bushnell E3s.
I've had a look at the video below, but would anyone have any guidance on how these traps could be fixed, what to look for, and potentially who to send it to for repairs, if needed (in the UK)?
Many thanks for your help with this!
