A lighting fixture with a motion detector is improved by incorporating an announcement device into the lighting fixture. The announcement device is a sound recording and playback device. When a person or an object enters into an area monitored by the motion detector, the motion will be detected...
The ultrasonic motion detector devices emit ultrasonic sound energy into an area of interest (monitored area), and this further reacts to a change in the reflected energy pattern. The system uses a technique that is based on a frequency shift in reflected energy to detect a movement or change...
Motion Detector Camera is a camera surveillance app, that uses the built-in camera to detect movements in the surrounding area using an advanced motion detection algorithm. If it detects movement, it can sound beep to notify you. When the motion detection camera detects changes, it starts record...
With the Go Direct Motion Detector, sound waves go out, reflect off an object in motion, and then come back to the sensor. It’s important to know that some objects are better reflectors than others. In general, people (i.e., students in your physics class) are good reflectors. To...
