Successful security is measured by the events that do not occur.
The primary goal in security is always to prevent losses. In the private sector, we predict outcomes, prevent problems and measure success in dollars and cents. Customer service begins and ends with enabling the client to do their own work without their having to be too aware of mine. Visible patrols are an active deterrent. Technology from architecture and engineering to biometrics returns value for the investment.
Disparities in hard numbers derive from the time frames of the data gathering. The industry is growing steadily, certainly arithmetically. Many guard companies are privately owned and do not report their income to private pollsters. Some estimates include passive devices such as cameras, while others only tally the guards who monitor them. Payrolls and staffs vary with the coming and going of contracts and competitive bidding makes some of that a zero-sum game. I worked one site where the customer got a competitive bid and changed guard companies. We all changed uniforms and got small raises. How the accountants at three companies recorded that might be interesting to explore.
