Doors/Entrances: If wooden, solid core, or metal reinforced doors should be used.
Exterior glass doors or glass windows in wooden/metal-reinforced doors
should be constructed of strong glass or laminated glass to increase
strength. Doors without windows should have a wide-angle (180 degree)
viewfinder installed (be aware that installing these viewfinders
may violate the door's warranty and reduce its fire rating). Door
locks should be at least single deadbolt with a minimum number of keys
available. Locks should be immediately re-keyed when a key is lost or
when an employee leaves employment. You should use non-duplication
keys to reduce the risk of unauthorized key reproduction.
Windows should also be of strong glass or laminated glass to increase
their strength. After market treatments are now available to help
prevent breakage during "smash & grab" style thefts. Use
window locks to prevent easy access. Secure crawl spaces, ventilation windows, attics connecting to neighboring
businesses, and any other opening. Seal mail slots in or near doors if
a wire device can be inserted to release the door lock.
Roofs: Use a shrouding
device on any roof access ladders to prevent unauthorized
access. Tree limbs should be trimmed to prevent climbing to gain roof
access. Other ways of gaining roof access are drain pipes, antenna
towers, and adjoining roofs. Secure rooftop skylights, air conditioning
and heating ducts, and other potential openings with grating. If they
cannot be secured adequately, you may want to consider alarming these
Fencing & Walls:
A fence, when feasible, is the first line of defense against the
thief. Fences and walls should be barriers to people but not for observation.
(Crime Prevention Through Environmental Design) principles and
techniques should be employed so a wall doesn't become a shield for a
criminal to hide behind while breaking into you business.
Landscaping & Lighting:
Another area where
is essential is in landscaping. Shrubs and trees should conform to the
2 foot 6 foot rule. Shrubs trimmed to 2 feet in height and tree
canopies trimmed to 6 feet and above. This keeps plants from becoming
hiding spots for criminals to commit their crimes. Shrubs that offer
prickly leaves, called "hostile vegetation" can offer
another layer of prevention.
Good lighting is a few more layers of prevention. Obviously it offers
a better opportunity for passersby to view any activity, but it also
offers a psychological deterrent. You may also consider leaving a few
low wattage lights on the inside back area of the business after closing to
silhouette intruders but not create any glare that might obstruct the
view from the outside.
Landscaping and lighting offer an abundance of crime prevention
strategies. To better understand how these aspects can help you,

of your business.
Safes: Do not leave large
amounts of money in your business. If you use a safe, it should exceed
500 lbs or be bolted to the floor and fire resistant.
