Action cameras are used to capture extreme action sports or activities. Regular cameras are incapable of capturing high-speed actions and are not designed for rugged conditions, including extreme weather. In contrast, action cameras are compact, lightweight, designed for rugged conditions, and can be worn on the person, or are mountable on vehicles. These cameras can capture high-speed and high-quality images.

A relay is used in electrical engineering to register overcurrent, overvoltage, reverse power flow, and over- and under-frequencies to avoid accidents or flashovers. It trips the circuit breaker when a fault is detected. If there is any discrepancy or abnormality in the current voltage or any other power measurement, the relay detects it and triggers an alarm. There are two types of relay: electromechanical relays and digital relays. Solid-state relays are electronic switching devices that operate on application of small external voltage across control terminals. Solidstate relays are smaller than electromechanical relays and are more reliable as they do not have moving parts.

IT is an integrated platform consisting of hardware, software, and services that help organizations store, process, transmit, and retrieve information. The IT department of an organization manages all IT-related services, solutions, and software that integrate and streamline various processes to facilitate a smooth flow of information across the organization. It also helps organizations align their business processes with various technologies to improve the overall efficiency.

Public safety and security is critical for a country's prosperity. One of the important aspects of public safety is mission-critical broadband communication. This can be achieved by using LTE, which is a transformation technology. Public safety LTE provides next-generation wireless broadband technology in mission-critical field applications, equipping people with the best realtime data, video, voice, and other forms of tactical communication. Private LTE devices have the ability to provide a dedicated spectrum for public safety so that users can safely access broadband applications and rich media services.

Ultrasound equipment generates high-frequency soundwaves that enable visualization of various internal body structures. Ultrasound imaging is considered safer than most other imaging technologies. One widespread application is detecting and viewing the fetus in the womb of a pregnant woman. Ultrasound equipment is extensively used by cardiologists, radiologists, surgeons, obstetricians, and other healthcare professionals. It is used to examine and diagnose diseases and other medical conditions in patients, such as tumors and gynecological problems.
