Welcome to Communication Systems Inc!

Also known as CSI, we were founded in 1975 by current owner Jim Landis as an installer of audio visual equipment. CSI now employs over 55 full-time technical and support staff members.

All CSI employees have passed rigorous background checks that we maintain for our work with schools, prisons, and government agencies. Ongoing training ensures our compliance with OSHA regulations and industry standard best-practices. Each year, CSI spends over $100,000 in training to ensure we have the best staff and intellectual resources.

While our growth has enabled us to easily handle large projects, we have maintained a local focus to ensure that we can provide the best support and service possible for the systems that we sell and install.

Located at 4670 Schantz Road in Allentown PA, CSI consists of three divisions: Sound & Video, Communication & IT and Life Safety & Security.
