An indoor dome camera is a type of surveillance camera designed for monitoring indoor environments such as homes, offices, shops, hotels, and schools. It is named after its dome-shaped housing, which protects the camera and gives it a discreet, modern appearance. The main components include a camera lens, image sensor, infrared (IR) LEDs for night vision, a protective dome cover, a mounting base, and sometimes a motorized pan/tilt mechanism. Many models also include features like motion detection, audio recording, and network connectivity (IP/WiFi).

In operation, the camera captures video through its lens and converts it into digital signals using the image sensor. The footage is then processed and either transmitted to a recording device such as a DVR/NVR or sent over a network for remote viewing on a smartphone or computer. The dome cover helps conceal the exact direction the camera is facing, enhancing security. At night or in low light, the infrared LEDs automatically activate, allowing the camera to record clear black-and-white images. Some advanced dome cameras can rotate or be controlled remotely to change viewing angles. Indoor dome cameras are valued for their wide coverage, unobtrusive design, and reliable indoor surveillance performance.
