Televisions and computer monitors are produced in such a way that they work for a certain part of the day and then shut down. Security system monitors are produced by calculating that they will remain open all the time. MTBF times for such monitors start at 30,000 Hours. This allows you to keep these monitors on at all times.

If it is to be used for image monitoring at a security point, you can definitely choose monitors that are manufactured for security or large area (LFD, Video Wall) monitors that are produced for 24/7 applications.
