Dr. Monzer Kahf, a prominent economist and counselor states: I can’t dare saying it is Haram to help in the security of human being whatever they do and wherever they may be. So as a job, this is not Haram as long as the job as described does not require you to do any forbidden act (such as poking, through cameras at obscene actions of strippers in casinos). However, this kind of job definitely helps the forbidden behavior and actions by those who do it and by those who make business of them. In as much as it helps these behaviors, it has a degraded level of consideration.”
