Motion detection can be used for security camera applications, wildlife photography, and for recording events where a person or other object, such as a car or truck, moves past the camera from time to time.
The GoPro Motion Detector X-Band Sensor with Cable for Blink and BlinkX is an active device powered by BlinkX/Blink’s 3.5mm Port2 connection, which bounces 10.5Ghz microwave signals to determine if motion has occurred. Microwaves do not rely on heat so the moving object does not need to be warm to trigger the sensor. Microwaves will also pass through glass and plastic, so the X-Band sensor can be mounted behind a window or inside an opaque waterproof box for use outdoors. The range of the X-Band sensor is adjustable from 8 to 30 feet (2-10m). Actual distances will depend on the environment and mounting configurations.
Blink and BlinkX are designed to extend the GoPro camera's battery life by turning the camera off between triggers and allows for motion detection triggering to be set on a scheduled active time to ensure footage is only captured when needed. In power saving mode, since the camera needs to power on before starting the recording, there is approximately a 5 second delay between when the Motion Sensor is triggered and when the recording starts or the picture is taken. Where power is less of a concern Blink has a "fast capture" mode (currently in Beta for firmware v2.00) where the camera will continue to stay on during the active motion detection schedule to reduce the activation time to less than 1 second. The camera will remain off when no motion detection schedule is active.
