Curiously, the camera doesn't beep when turned on with the remote, so unless you have an assistant standing by to look at your little light it's awfully hard to tell whether you're recording.
For instance, if two crossings are close to each other neither will beep in case pedestrians are misled into walking out into oncoming traffic on the wrong road.
The raised slider is textured and easy to find, even with gloves on, and there's still the reassuringly loud beep to let you know that you have, indeed, started filling up your memory card.
