Custom systems are those that are built to the customer's specific mission requirements. For example, if the requirement is for a Portable Surveillance System that provides both daytime and nighttime video recording, then OMAI will build a system to that specification which provides a daytime video recording camera and a night vision device to fit that camera for nighttime use.

Custom systems range from wheeled vehicle mounted to aircraft mounted systems, and all come with an operator's manual specific to the kit. OMAI also provides operator training for the use of custom systems.
