Intrusion detection encompasses perimeter security and intrusion detection sensor technologies. Security specialists employ intrusion detection sensors to secure the perimeter of secured areas and locations. Included reports: highlight, summary, and handbook.

Intrusion detection and prevention systems are used to detect and identify possible threats to a system, and to provide early warning to system administrators in the event that an attack is able to exploit a system vulnerability. These systems are instrumental in capturing and logging information that can later be used to investigate a data breach. Included reports: highlight and application note.

Intrinsically safe exhaust fans are used by responders during rescue operations to ventilate confined spaces or enclosed areas with contaminated atmospheres. Intrinsic safety is achieved by making certain that only low voltages and current enter hazardous areas, ensuring there is no ignition hazard. Included reports: highlight, summary, focus group report, market survey report, and assessment report.

Integrated night vision systems combine image output from two or more different types of night vision sensors into one composite image in order to take advantage of the strengths of each type of sensor. These systems provide responders with enhanced detection and recognition capabilities in fog, rain, and smog, as well as in poorly illuminated conditions. Included reports:highlight, summary, technote, focus group report, market survey report, and assessment report.

In-suit communication equipment may include an earpiece, voice piece, and push-to-talk capabilities. This equipment facilitates communication with and between responders wearing personal protective equipment. Included reports: highlight, focus group report, market survey report, assessment report, and technote.

Impact resistant doors are designed with strength, security, and durability in mind to ensure they are able to protect secured areas. They are used in both interior and exterior applications and are commonly found in high-security areas. Included reports: highlight and handbook.

Imaging sonar is a high-frequency, narrow field of view, underwater sonar that produces video-like acoustic imagery that can detect and identify submerged objects of interest, even in low-to-no visibility conditions. Imaging sonar systems are used by responders to inspect ship hulls and  pier and bridge pilings, direct divers to objects of interest, track divers underwater, and search for underwater obstructions ahead of vessels. Included reports: highlight, summary, focus group report, market survey report, and assessment report.
