All outside or security doors should be metal-lined and secured with metal security crossbars. Pin all exposed hinges to prevent removal.
Be sure your safe is fireproof and securely anchored. It should be kept in plain view. Leave it open when it's empty, use it to lock up valuables when you close. Remember to change the combination when an employee who has had access to it leaves your business.
Before you invest in an alarm system, check with several companies and decide what level of security fits your needs. Learn how to use your system properly. Check the system daily and run a test when closing.
Check the parking lot for good lighting and unobstructed views.
Keep your cash register in plain view from the outside of your business so it can be monitored by police during the day or at night. Leave it open and empty after closing.
Light the inside and outside of your business, especially around doors, windows, skylights, or other entry points. Consider installing covers over exterior lights and power sources to deter tampering.
Make sure all outside entrances and inside security doors have deadbolt locks. If you use padlocks, they should be made of steel and kept locked at all times. Remember to remove serial numbers from your locks to prevent unauthorized keys from being made.
Windows should have secure locks and burglar-resistant glass. Consider installing metal grates on all your windows except display windows. Remove all expensive items from window displays at night and make sure you can see easily into your business after closing.
