Except for the more garish super villains, criminals avoid the spotlight. Most prefer to operate in theaters where they can remain in the shadows and maintain a level of control. Enter Crime Prevention Through Environmental Design (CPTED). CPTED is not a new sensor or camera. Rather, CPTED is a set of design principles intended to take the sense of anonymity and control away from the bad guys; and by doing so, make your facility a harder target. CPTED principles, when properly applied, allow you to anticipate the thought process of potential offenders and reduce the opportunity for crime.
The Four Principles of CPTED are Natural Access Control, Natural Surveillance, Territorial Reinforcement, and Maintenance. In the remainder of this post, we’ll briefly describe each and give you practical ideas for using them in your business.
Electronic Access Control (EAC) systems are designed to control the flow of traffic in and out of buildings and lots. No one should be able to enter an EAC protected area without some form of valid credential. Natural Access Control, by contrast, does not prevent anyone from entering your area; it just directs them to enter on your terms. A simple tension barrier, for example, can help take away a sense of control from an intruder as they approach a bank teller line or cash register. Here are some ideas for putting Natural Access Control to work for you:
In summary, Natural Access Control means that you, not a potential offender, are in control of the traffic flow in your space.
Open, well-lit spaces can deter crime, while isolated areas can encourage mischief by providing a cloak of anonymity. To avoid recognition, criminals will choose situations where they can hide and easily escape. So how do you keep your environments open to view? Here are a few tips:
When someone with ill intent encounters a prudent use of natural surveillance, they should feel like they are being watched, and that there is no easy way to disappear from view.
Territorial Reinforcement should create a clear distinction between public and private spaces. This is important for two reasons: Legitimate occupants have a sense of ownership and will notice - even challenge - people who don't belong; intruders, on the other hand, will have a harder time slipping in unnoticed.
Here are some basic examples of territorial reinforcement at work:
As the principles of Territorial Reinforcement are implemented, employees and guests gain a sense of ownership, and intruders are put on the defensive.
Remember the old Granville House from It’s a Wonderful Life? George and Mary make their wishes and throw rocks at the windows to make sure they come true. And why would a wholesome couple perpetrate such brazen vandalism? Mostly because the other windows in the Granville House were already broken. It’s a great illustration of the CPTED Maintenance principle in action. Broken windows invite more broken windows.
A well -maintained area sends the message that people notice and care about what happens. This in turn discourages vandalism and other crimes. Security practitioners refer to the Broken Windows Theory; the idea that one broken window will entice vandals – or young lovers - to break another. A vandalized area then becomes more inviting to higher levels of crime. This principle is easy to apply. Property should be well-maintained as a matter of safety as well as pride. No one threw rocks at the Granville House after the Bailey’s moved in, now did they?
While not one of the accepted CPTED, Target Hardening is often mentioned in conjunction with CPTED. Target Hardening simply means making a building or sensitive area more difficult to breach. Target Harding is often achieved by installing electronic and mechanical security devices. Here are a few examples:
By adding layers of security that make your business harder to attack, you are encouraging criminals to victimize someone that hasn’t been quite so diligent.
CPTED principles have been steadily revised and applied since the 1970’s. While CPTED began as a way to defend entire communities, security practitioners have also adapted the practice to the commercial environment. Are you ready to apply CPTED to your space? Begin with a thorough walk through of your building and campus. Check for clear sightlines, notice the approaches to your property, and make sure your borders are well defined. Note any maintenance issues and resolve them before they attract vandalism or crime. For even more help, you can contact local law enforcement and arrange for a Community Resource or Crime Prevention Officer to survey your business and produce a formal CPTED review. Whichever approach you choose, begin today to use your environment to protect people and assets.
