After the Launch: Perseverance Mars Rover Update

Anyone know what the commodity "ruggedized sports cameras" they refer to might be? They make it sound like they truly used COTS cameras, which isn't normal for a mission like this.

I'd be interested in reading about how they were modified to make them survive the environment they will be subjected to. My guess is that these cameras were not necessarily designed for long lifetime, probably just to capture the landing sequence, transfer to rad-hard rover storage and that's about it.
