Is the red dot on the smoke alarm hiding the camera?

The red dot on the smoke alarm is not a hidden camera.
Firstly, we need to clarify the definitions and characteristics of smoke alarms and hidden cameras:
Smoke alarm: It is a fire warning device used to detect smoke and harmful gases. It detects the presence of smoke by detecting changes in the intensity of scattered infrared light in the smoke, and issues an alarm when smoke is detected. Smoke alarms typically have a red indicator light that flashes during normal operation to indicate that the device is running. ‌
Hidden camera: It is a small, inconspicuous surveillance device that can be installed in various concealed locations and records video or audio information through wireless transmission or storage cards. Hidden cameras usually do not emit obvious red light or flicker to maintain their concealment. ‌
Next, we will analyze the question of whether the red dot on the smoke alarm is always on and whether the camera is hidden
The working principle is different: the working principle of smoke detectors is based on smoke detection, while the working principle of hidden cameras is based on video recording and transmission. There are essential differences between the two in terms of function and purpose. ‌
Appearance and installation location: Smoke alarms are usually installed in hard to reach areas, such as high ceilings, and have a uniform appearance with clear red indicator lights. Hidden cameras, on the other hand, place more emphasis on concealment and can be installed in various concealed locations, with potentially more diverse appearances. ‌812
The meaning of flashing red light: The flashing red light on a smoke alarm usually indicates that the device is operating normally or detecting smoke. However, hiding the camera will not emit such a flashing red light. ‌
