Need Help With Monitoring Software Selection

So I tried one software suite (Spyrix) and it was a nightmare, BitDefender kept kicking up false positives over and over again. I went so far as to add every executable in the program's directory and even the entire directory to the exemption list and it was still getting flagged.

Kudo's to bitdefender for being good, but that's a little too good.

So my question is, does anyone have any recommendations for monitoring software that:
1. Works with bitdefender
2. Stores files on a local network machine (I have a NAS I would like to use as the data storage)
3. Does not require a monthly subscription (preferred but not mandatory)

I should also add the 4 things I am looking for in a monitor. Network traffic logging, screen monitoring, webcam use monitoring, and keylogging. Basically trying to lock a system down before handing it over to the user.

Thanks in advance.
