What are Motion-Activated Security Bulbs?

Definition of Motion-Activated Security Bulbs

Motion-activated security bulbs, also known as motion sensor bulbs or smart bulbs, are lighting devices that incorporate motion detection technology. These bulbs are designed to turn on automatically when they detect movement within their range of coverage. They are typically used for security purposes, illuminating outdoor areas such as driveways, entrances, and backyard spaces.

Principle behind Motion-Activated Security Bulbs

The principle behind motion-activated security bulbs lies in the integration of motion sensors with the lighting system. These sensors are capable of detecting infrared radiation emitted by moving objects. When the sensor detects movement, it sends a signal to the bulb, prompting it to switch on and provide illumination in response to the detected motion.

Benefits of Motion-Activated Security Bulbs
