GoPro X Band Motion Detector - Sensor with Cable for Blink and BlinkX


Our X-Band Motion Sensor is an accessory for Blink or BlinkX that uses doppler detection to determine if motion has occurred by bouncing 10.5 GHz microwave signals off the objects in front of it.

      • 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 X-Band Motion Sensor does not work underwater.

        Our X-Band Motion Sensor 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.

        The X-Band Sensor is typically used with our durable weatherproof SolarX or DryX enclosures that have enough space to house the GoPro, BlinkX/Blink, Motion Sensor, and Battery Packs.

        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.

        • Microwaves do not rely on radiated heat from the object, it is well suited for detecting smaller wildlife as well as larger objects. It is also less prone to false triggers caused by moving sunlight, etc.
        • Microwaves will pass through glass and plastic, but not metals, so the X-Band detector can be mounted inside a window, or in a weatherproof box for use outdoors.

        • Programmable "active shoot time" to avoid capturing extra footage
        • Capture single shot, multiple stills, or video.
        • Trigger the camera between capturing regular interval time lapse images.

      • Frequently Asked Questions

        Do I require Blink or BlinkX to use the X-Band Motion Sensor?

        Blink or BlinkX is required to use the X-Band Microwave Motion Sensor accessory to trigger the GoPro camera when motion is detected.

        How does the Motion Detection video recording time work if motion is detected more than once in the interval?

        If the video mode is selected in the Motion Detector interface of Blink/BlinkX, the camera will continue to record for the amount of time set in the Video recording menu once motion is no longer detected. If movement is detected before the recording time elapses, the recording interval will be reset to ensure you capture the entire motion event.

        How does the X-Band detect motion?

        The X-Band sensor uses doppler detection of microwaves bounced off the object and is triggered by motion towards or away from the sensor. Microwaves pass through opaque plastics and glass, but not metal. The moving object does not need to be warm to trigger the sensor.

        Will the X-Band Sensor work underwater if contained in a waterproof housing?

        No. The X-Band Sensor only works in air and will not work underwater.

        Can I use more than one sensor with Blink or BlinkX simultaneously?

        No. Blink and BlinkX detect pulse frequency from the X-Band Sensor, so only one sensor can be used at a time.

        Does the controller board fit inside the standard waterproof case?

        BlinkX does not fit into any of the standard GoPro housings. Blink fits in the extended BacPac backdoor attachments included in the GoPro Backdoor Kit and provided with the GoPro accessories such as the GoPro Dive Housing, GoPro LCD BacPac or the GoPro Battery BacPac. However, since the Motion Sensor plugs into the 3.5mm port on the bottom of Blink, a small hole needs to be drilled into the housing to allow the sensor’s wires to pass through the housing. X-Band detectors are normally used with our outdoor SolarX and DryX enclosures.

        CamDo offers a series of Outdoor Weather Resistant Enclosures designed to house the GoPro camera, Blink, and Motion Sensor along with space for a high capacity battery and optional solar panel for longer term deployment. The X-Band detector fits inside the weather resistant case and does not require any hole in the case for installation of the X-Band Sensor.

        Can a Blink or BlinkX motion detection schedule and time lapse schedules overlap?

        Yes, the motion detection can be set on a schedule that overlaps with a time lapse schedule. If the camera enters a time lapse interval while camera is currently recording in motion detection mode, the time lapse image will be skipped. If the camera is currently taking a time lapse image when motion is detected, Blink will re-trigger the camera on the motion detection schedule after the camera has taken the time lapse photo and turned off.

        I am a hacker. Can I use the ports on the Blink or BlinkX board to trigger the camera using other devices?

        The motion detection Port2 of Blink and BlinkX can be programmed to accept an external input to trigger an action. Unlike the X-Band operation which requires a set amount of pulses within a certain timeframe, PIR/External mode only requires a pulse for more than 250ms to trigger the camera. See this blog post for more details.

        I am a not a hacker. I have an idea for a project for our organization. Can you help?

        Yes. Our controller boards were originally designed to handle custom projects we built for scientists and professional photographers. Our controllers are very flexible and can be reprogrammed to respond to different kinds of control inputs. Some controllers also have an output which can be used to control lighting, or give different types of feedback. Contact us for a quote for your application.
