The Labrador office had a sign posted about surveillance and voice recording... But I've not seen the sign for a while.

I don't know if it fell down or if they moved it. I had a look about reception area to try and see it when I was last there, but I couldn't see it.

I personally don't believe it's necessary for a DoCS office to record voice... Filming is too common to worry about - but there's no reason to record voice.

The only reason that comes to mind is slight of hand, sneaky activities.
