These programs usually run in the background of your computer and keep track of the way that the computer is used. Some keep a log of sites visited, of emails written and received, or of online chat sessions, while others store screenshots so that you can see exactly what your children are seeing -- every monitoring tool does its job in a unique way. Some parents view monitoring more as a deterrent mechanism, thatc can allow them to control their kids' online access without resorting to restrictive filtering or blocking tools.
Many monitoring tools record everything, or as much as is feasible, about what goes on on your computer or through your online access. Some can record the ways in which your computer is used even when it is not connected to the Internet. Almost all of these tools are designed to be as comprehensive as possible.
Many monitoring tools can give parents control of their kids' Internet access by giving them information about their children's online habits. If used secretly, however, they might foster resentment in older kids who don't appreciate feeling that their parents are constantly watching over their shoulders. Any of these tools should be used carefully by parents.
Because monitoring tools' function is often to record information, they are usually well-equipped to handle all forms of new online content.
Physical safety protections
These tools can help to ensure children's physical safety by letting parents know if their kids are involved in inappropriate or dangerous online relationships. Parents can then work to protect their children in whatever ways they see fit.
Assuming that the monitoring software is in good working order, its use should not interfere with online functionality at all.
