Apologies if this was covered - I searched previous posts and didn't see anything.

In season 1, Sarah (as Beth) finds the surveillance equipment in the trunk of the car. Presumably returns it to Raj at the station? Then in season 4 Sarah and Art go back to Beth's apartment and take the camera out of the wall. They watch the footage, learn about the Neolution woman, etc etc.

Did Raj just never get that camera back then? You would think he'd continue to bother Sarah/Beth about a partially returned surveillance set!

It's definitely not a major plot point. Something that randomly popped into my head on a recent rewatch. Thanks for your thoughts, sestras!
