Founded in 1986, Sealevel is an American-owned designer and manufacturer of critical communication products, I/O and industrial computers. Because the needs of our customers are ever evolving, we’re continually developing new products that leverage emerging technology and the growing Industrial Internet of Things (IIoT). The Sealevel Facility
Located in the upstate of South Carolina, our modern, 5

2,000-square foot facility sits on a 17-acres site. To protect electronic components during assembly and test, we've installed over 20,000 feet of ESD tiling. Putting the I/O in IIoT
Sealevel's SeaConnect family of IIoT products is one of our most popular and fastest growing lines. Currently, we are working with many customers to implement cellular-connected applications in a variety of vertical markets.

AI at the edge brings intelligence closer to where decisions happen. Getting it there is the hard part.

Limited compute resources, power constraints, cybersecurity, software optimization, and deployment at scale can all stand between an AI model and a successful real-world application.

So, how do engineers overcome those challenges?

Explore what it takes to move AI from concept to deployment at the edge.
