“Why did we choose Lappen Security? Because of the great service. The folks at Lappen listened to our needs and worked with us to install a great video camera security system. Lappen’s office staff and installation technicians were knowledgeable about the equipment and also offered suggestions on how to improve our camera locations and displays.”

– Bret Jaeger, Director, Waupun Public Library

“I just wanted to take the time to thank you for your excellent services. I came in – not having a clue about keys or locks – and the employees treated me with the utmost respect. I wanted to thank the employees for going out of their way for me and fixing the problem until there were no flaws. The employees were very helpful and truthful. I will definitely forward Lappen Security Products to anyone else that may need this type of service. Thank you.”

– Kayla, Recent Customer

“We were rather new to the security game when we called Lappen for help. They made the technology understandable in layman’s terms and gave several suggestions on how to use the current technology to its fullest while staying within a reasonable budget. The system we have today far exceeds our initial expectations and our building is a much safer and secure place to work. I would recommend Lappen to any business in need of security expertise.”

– Jim Goehler, Graphic Packaging International
