I am not going into the technical side of things. However, I am going to the legal side of things.

You say that you want to record classes that you teach. Firstly you need your students permission to record, thankfully they are adults. However, if you have a class of ten for example, and one person does not give you permission, then you are going to have to get rid of him or her, so that you can record.

You can technically say that you will use video editing software to blur out their faces, but you still have raw footage of people. You will have to look into the legal issues depending upon which Country you are in as they are all different, some stricter than others.

You are looking at a legal minefield which ever way you want to go. I a year ago set up recording equipment due to anti social behaviour, it was not recording people's faces only audio. However, as it was catching some video e.g it was looking at a brick wall, I was told that I need a CCTV (closed circuit television license) to operate it from the local council. 

If say for example you have a professional complaint against you of a naughty nature, and your footage shows that you was focused on one student's cleavage to give an example, you are bang to rights.

A camera at the back recording people's heads and recording your teaching methods you can possibly get away with more, because you are analysing your teaching. The camera recording people coming into the class will still be an issue.

To cut short, seek proper legal guidance before you go spending any money on software.

I don't know what you're involved in or what the heck is going through your head. My business is professional and no intention of any peeping for cheap thrill recordings, it's for work. There are plenty of porn sites to get that stuff from.

I am recording myself and myself only teaching classes, there is no reason for students to be in any video. There may be audio of them asking questions and me answering them.
I will have disclosures and authorization releases in my student enrollment forms they must agree to in order to join the classes that we will be recording in class audio /video and they give us full permission without compensation to use it however we see fit including distribution resale, etc. and the rights to it without any compensation or permission of theirs and if they don't want to then don't join the class. Just not worded like that obviously but something to that effect.

I was just making an inquiry here as to the techie side of things, not the legal.
