Although the surveillance recordings are in a hidden location, ethical use of PC Prowler requires the system manager to let every other user on the system be aware that they are being monitored. This program is meant to be used to help protect the system from being misused or abused, not to secretly spy on other system users. This is easily understood when comparing the use of PC Prowler on the computer to the use of surveillance cameras in a public common area such as a shopping plaza or a bank. People are made aware that they are being monitored by signs placed in conspicuous locations and it helps to promote a feeling of safety and wellbeing. It is common knowledge that these surveillance cameras can also help to deter criminal activities. There are instances when, of course, this is not the case, but generally surveillance cameras are a good thing. PC Prowler's functionality works similarly to this common comparison.
