What are the uses of motion detectors?
The detector senses a person is moving (motion) and a switch is set to on. It depends on why the motion sensor was installed. Maybe an warning alarm is sounded, a camera could begin to record, or a light in the room or passageway is turned on.
What is the difference between a SLR and DSLR camera?
A SLR camera uses film while a DSLR camera uses a digital sensor to capture images.
What is the difference between an SLR camera and a DSLR camera?
An SLR camera uses a film to capture images, while a DSLR camera uses a digital sensor to capture images.
How does a Wii work?
it uses motion sensor technology
How does wireless motion sensor work?
A wireless motion sensor typically uses passive infrared technology to detect changes in heat signatures in its surrounding environment. When it detects movement, it sends a signal wirelessly to a connected device or system, such as a security camera or alarm system. This allows for remote monitoring and alerts based on detected motion.
How much electricity does a motion sensor light use?
A motion sensor light typically uses around 1-20 watts of electricity, depending on the brightness and type of bulb used.
What are some potential uses for a micro camera?
Some potential uses for a micro camera are spying, theft protection and security. A micro camera can be concealed and difficult to find on normal occasions.
How can a thermal imaging camera produce a picture in the dark?
it uses infared and heat sensor to make a visible image
What is an ultrasonic motion sensor?
An ultrasonic motion sensor is a device that uses high-frequency sound waves to detect movement within its range. When an object moves in the vicinity of the sensor, it reflects the sound waves back to the sensor, which triggers a response or alerts the system to the motion. Ultrasonic motion sensors are commonly used in security systems, automatic doors, and occupancy detection systems.
What kind of technology does a Wii use?
the Nintendo wii uses motion sensor technology can buy it for around £2000
What does the AF assist button do?
The AF (autofocus) assist button activates the autofocus feature on your camera. In general, the AF system uses a sensor and a motor to automatically focus the camera on a subject.
What is the difference between a DSLR and an SLR camera?
A DSLR camera has a digital sensor to capture images, while an SLR camera uses film. Additionally, a DSLR allows you to view the image through an electronic display, whereas an SLR uses a mirror system to reflect the image through the viewfinder.
