Setup and recording with the Dual Hero System is very easy and straight forward. If you know how to record with a GoPro previously, you are already ~90% there.
Step 1 - Get your cameras and SD cards
Before getting started, you will need 2 Hero3+ Black edition cameras running the same firmware (2.0 or higher).
We recommend having 2 identical SD cards (both class 10, both formatted, and preferably the same brand) You can use 2 different SD cards, but it is imperative to be sure that they are class 10. Different brands and capacities are also okay, but we highly recommend identical cards.
Step 2 - Insert cameras in the housing
With the lens facing away from you, the right camera or ‘master camera’ gets inserted into the right hand side of the housing. The Left camera or ‘slave camera’ gets inserted upside down into the left hand side of the housing.
Step 3 - Connect the Dual HERO BacPac
You will need to connect both cameras to the Dual Hero BacPac which is included in the Dual Hero System packaging. The Larger half of the BacPac is connected the right master camera and the smaller half is connected to the left slave camera.
Once the BacPac is attached, the cameras automatically sync and all the settings for both cameras will be mirrored (except for the left camera automatically going into upside down mode). At this point, the cameras operate as one.
Shooting video, photos, bursts, and time-lapses, are all identical to using a single GoPro camera. The only exception being the new Dual Hero Mode.
ALL Resolutions, frame rates and capture setting modes are supported. The only exception is that .5 second and 1 second time-lapse are NOT supported on the Dual Hero System.
How to record
For all modes, the shutter button will start and stop recording for both cameras. The mode button will change the modes of both cameras. The Dual Hero System may take an extra second or two when the recording stops to save both recorded files to both SD cards, and maintain the sync. We recommend giving the Dual Hero System some extra buffer time between recordings. (2-5 seconds) You will know when the Dual Hero System is ready when both camera’s file counters are present.
All recordings with the Dual Hero System will start and stop in perfect sync and unison. Anything out of sync can be considered an error. If a sync error occurs, both camera’s recordings will stop and “sync error” will be shown on the camera’s LCD screen.
Using the Dual HERO System with Wi-Fi
You have the ability to use the Dual Hero System with Wi-Fi. Remember that you are only using the master camera’s Wi-Fi. The slave camera’s Wi-Fi will not be used. All of the commands, operations, and instructions are controlled by the master camera. The slave is simply along for the ride.
You will need to have GoPro App v.2.3 or higher installed in your iOS or Android device for use with the Dual Hero System. You will need at least v.2.2.1 or v.2.1.7 installed on your Wi-Fi Remote for use with the Dual Hero System.
The process of pairing the Dual Hero System to a remote or the GoPro App is identical to the process when only using one GoPro:
With the GoPro App, the user interface will be the same except for displaying additional info for the second camera. You will see additional battery info, SD card info, camera name info, and record time info for both of the cameras in the Dual Hero System.
With the Wi-Fi Remote, you will only see the status of the master camera be reflected on the remote’s LCD screen.
Using Dual HERO mode
Dual Hero Mode enables the user to capture video from the master camera while separately recording full 12mp time-lapse from the slave camera. Both cameras will display their individual status screens for the respective mode that they are shooting in (video for master and time-lapse for slave).
