The CamDo Bullet is a low power GoPro accessory for the HERO3+ and HERO4 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 for each set of Bullets, since the remote is necessary to trigger the first camera in the chain.


Remote Control of Multiple GoPros

Through the use of the wired remote, trigger as many GoPro cameras as you want with a push of a button.

Create Professional Time Slice Videos

Daisy chain multiple GoPro cameras together, each outfitted with a Bullet to synchronize footage to create impressive time slice video. 

Low Power Consumption for Extended Use

Bullet is a low power accessory that allows you to control one or more GoPro cameras without the considerable power required for WiFi. Used with the Wired Remote to control the power and shutter functions of your cameras, your camera’s battery life is extended and controlled.

No Custom Firmware Update Required

Unlike our previous wired remote, the Bullet doesn’t require a custom firmware update process in order to work. Just ensure your HERO3+ or HERO4 camera is up to date with the latest firmware from the GoPro website.

    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. Bullet has a mini-USB input that allows you to power the GoPro through the HERO Port. Powering the GoPro from the HERO Port does not charge the battery which makes the camera more reliable when recording for long periods by removing the heat generated by the GoPro battery charging circuit. This also bypasses the problem that users have had with the HERO3+ charging logic that causes the camera to freeze and require a reset when operating the camera while it is charging.

    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.
