Bullet Time Slice

For HERO5 Bullet functionality, see the BlinkX page.

Using Bullet is very simple. Just plug it into the camera and press the button on the Wired Remote. If the camera is off, it will turn on. If the camera is on and in photo mode, it will act as if you have hit the camera shutter button and take a photo. If in video mode it will start or stop video. Holding the button for more than 3 seconds will turn the camera off.

  • The CamDo Bullet is a low power GoPro accessory for the HERO3+ Black, HERO4 Silver, and HERO4 Black cameras that allows you to control the GoPro camera's power and shutter functions through the use of a wired push button remote. Bullet can be used to control a single camera or multiple cameras using a single remote. Each Bullet is purchased separately and has an input and output port, allowing the boards to be daisy-chained so that any number of cameras can be triggered simultaneously.

    Each Bullet comes with a 1 foot patch cable for daisy-chaining between Bullet boards. If the cameras need to be placed further apart or you need a longer cable between the first bullet and the push button remote, we are offering extension cables at 3ft, 10ft, and 25ft lengths.

    BULLET DOES NOT INCLUDE A PUSH BUTTON REMOTE. Be sure to also purchase a LED Wired Remote as a trigger for each set of Bullets. If you need extra length for your wired remote or between each Bullet, we have Extension Cables here.

    • Trigger the power and shutter functions of the HERO3+ Black, HERO4 Silver, and HERO4 Black cameras using a simple trigger input from a wired push button remote.
    • The Wired Button Remote can be replaced with a microcontroller or another trigger. See the Bullet User Manual for details.

    wb_incandescentLED Feedback

    • Outputs a feedback signal for the LED Wired Remote that mimics the red LED on the front of the GoPro camera: flash once to indicate taking a picture, and flash continuously to indicate that the camera is recording, etc.

    • Each Bullet has an input and output port, allowing the boards to be daisy-chained so that any number of cameras can be triggered simultaneously.
    • Each Bullet includes a 1ft patch cable for daisy-chaining multiple Bullets.

    • Daisy chain multiple GoPro cameras together, each outfitted with a Bullet to synchronize footage to create impressive time slice video.
    • When used with a PowerPad, each camera can be switched from connected (for downloading images) to disconnected (for powering allowing image capture) under the control of a host computer allowing the use of multiple cameras without the need to plug and unplug cables or remove the SD cards from the cameras.

    powerLow Power Consumption for Extended Use

    • Bullet is a low power accessory that allows you to control one or more GoPro cameras' power and shutter functions without the considerable power required for WiFi.

    photo_cameraNo Camera Firmware Update Required

    • Unlike our previous products (Programmable Scheduler, Time Lapse Intervalometer, and Motion Detector), Bullet doesn’t require a complicated camera firmware update process. Just ensure your HERO3+ Black, HERO4 Silver, or HERO4 Black camera is up to date with the latest firmware from the GoPro website or through the GoPro App for iOS and Android.

  • Frequently Asked Questions

    I want to control 4 cameras simultaneously through a remote, what do I need to purchase?

    1 x Wired Remote + 4 x Bullets

    Can I power the GoPro camera from Bullet?

    Yes, but the GoPro battery is still required for reliable operation. Bullet has a mini-USB input that allows you to power the GoPro through the HERO Port. However powering the GoPro from the HERO Port does not charge the battery so the GoPro battery will need to be recharged separately.

    Can I make a custom trigger for the Bullet?

    Some users may want to trigger the Bullet with something other than a shutter button. This is possible, however caution must be taken to ensure the Bullet or camera does not become damaged. See the user manual under the section “Building a Custom Trigger” for more info

    I need to take photos at exactly the same time. How accurately synchronized are the cameras when I use your cables?

    The Bullet does not synchronize the shutter. When the button is pressed, a command is sent to each camera at the same time, however we cannot guarantee that all of the cameras will respond at exactly the same time.

    If the shutters are not synchronized, how can I make a bullet time-slice video?

    Typically, our customers shoot video when the cameras are turned on. For 120fps video, the HERO4 can achieve 1080p quality and is a set up that many of our clients use to achieve tight synchronization in post production to achieve such effects as bullet time slice (made famous by the matrix movies). The sound track can be used to provide a synchronizing signal, as simple as a clapper board, or sometimes music. The frames are then grabbed from the video tracks in post production using software such as PluralEyes, AutoPano, PTGui Pro, Adobe Premiere or other products./p>

    Does the controller board fit inside the standard waterproof case?

    Bullet does not fit in the GoPro Housing with the standard backdoor. Bullet fits in the extended backdoor attachments included in the GoPro Backdoor Kit and provided with the GoPro accessories such as the GoPro LCD BacPac or the GoPro Battery BacPac.

    How much does each Bullet weigh?

    Bullet weighs 14.5g. The Bullet's PCB without the housing weighs 6.8g. Bullet's PCB can be removed from the housing using a set of Torx screwdrivers size T3 and T5.
