As much as can be correctly said here is that yes, you
can be charged.
Whether or not you
will be charged is a case specific operational policing decision
about which
@Adam1user can have no reliable knowledge.
Now, let's say, for the purpose of discussion, that the act(s) took place in NSW.
In NSW, a person who does acts like those you're asking about
can be prosecuted for (at least) the offence called (for short)
"
Filming A Person Engaged In A Private Act".
Subject to the facts and circumstances, further offences relating to unlawful use of surveillance devices
could also be on the table.
Understand that, as matter of legal definition, "filming" also means stills.
Let's also be clear about a couple of other things.
1. A person can't consent to something that they didn't know was happening.
Which means, as a matter of logic, that they cannot consent retrospectively ("after the event") either.
2. It doesn't matter if the person depicted/ recorded ever complains or not - the offences are still on the table.
3. If an accused contacts the person in the images/ footage, and tries to persuade them
to lie (say, to police) for the accused's benefit (such as by saying they knew, and/or consented),
then there is the possibility of separate, additonal, offences involving influencing witnesses,
and perverting the course of justice.
Lastly - if the worst thing that happens is that you lose your job (for, say, using company property to commit what might be offences), take that as a lucky escape.
