Video recording without sound for privacy reasons

[orange turtle]

My research involves high-risk/vulnerable populations and I will be using video recordings. The ethics board has okayed video recording on the condition I guarantee there will be no audio captured because of the sensitive nature of the material that might be captured.

Does anyone know of any video equipment I can buy that will guarantee that? The only way I know how right now is to mute the video recorder, but if I can buy a specific type of video recorder, I would much rather do that so I am not on any grey zone. I have to buy the video recorder anyway, so it's best I invest in the right one from the beginning.

Thank you.

might be hard, maybe try DSLRs that can record video as well (but they also seem to have mics). or perhaps security cams that don't have mics?

Can you get a electrician to disconnect/damage/disable the mic in a way that it is permanently unable to record sound? Or, can you tape up the camcorder's mic in case you ever forget to mute the mic?

@.letmeinplz//, @TakeruK: Thank you for the suggestions. I will bring it up with my PI at the next meeting and see what she says!
