iBLOCK is a new product line developed by IVS Imaging (dba Costar Video Systems, Inc) & launched officially 4/1/14. Competitive Advantage: No other direct competition on the market that has developed a system like this. Where the ability to build a camera modularly that fits the exact specification given is unique. As we continue to develop more cameras & interface boards we will only push to standardize this practice across all of our camera lines.
