Monitoring something or someone does not necessarily mean invading privacy; most of the time, we do it for security reasons. I mean, there must be a very good reason you're on this page, right? Recording should be fine as long as at least one of the parties involved has consented. Otherwise, you may be subject to legal claims and charges. Note that when you do this, be vigilant as well.
