Body‑worn cameras (BWCs) have moved from niche surveillance tools to essential technology for law‑enforcement, private security, and a growing range of commercial and industrial applications. By recording audio and video from an officer’s or worker’s point of view, BWCs promote accountability, improve evidence collection, and enrich training and operational insights.

What Is a Body‑Worn Camera?

A body‑worn camera is a compact, ruggedized video‑recording device that attaches to a user’s uniform, vest, or helmet. Modern BWCs typically feature:

• High‐definition video (1080p/4K) with low‑light and wide‑dynamic‑range capabilities

• Integrated microphones for synchronized audio capture

• On‑device storage and/or live streaming over LTE, 5G, or Wi‑Fi

A capacitive sensor is an electronic device that detects and responds to changes in capacitance caused by the presence or movement of an object. These sensors are widely used in modern electronics, industrial automation, consumer devices, automotive systems, and medical equipment due to their reliability, sensitivity, and versatility. From touchscreens to proximity sensing and level detection, capacitive sensors play a critical role in human-machine interaction and automated systems.

What is a Capacitive Sensor?

A capacitive sensor operates on the principle of capacitance—the ability of a system to store an electrical charge. It consists of two conductive plates separated by a dielectric (non-conductive) material. When an object (usually conductive or with a different dielectric constant than air) comes close to or touches the sensor, the capacitance between the plates changes, and the sensor responds by triggering an output signal.

Capacitive sensors can detect:

• Touch (like a finger on a screen)

• Proximity…
