This manual describes how to get started with your CamDo Blink Time Lapse Controller for your GoPro HERO4 or HERO3+ Black camera (NOTE: HERO3+ Silver cameras may work but are not officially supported by CamDo due to the general unreliability of the HERO3+ Silver cameras as they get older). Blink is a low power, WiFi enabled GoPro time lapse and scheduler accessory that unlocks the full potential of the GoPro camera. Blink allows users to control when and how the camera will trigger based on a daily schedule, motion detection, or other custom made triggers. Configuration is handled through an easy-to-use web interface via a smartphone, tablet or laptop. Read our Quick Start Guide to get started and this more detailed User Manual for further details. You can also view helpful instructional videos in the “Support” section.
A. CamDo Blink
B. Wired Remote
C. USB OTG Cable (for future updates)
D. X-Band Motion Detector (optional purchase)
1. miniUSB: Blink's USB interface is used for firmware updates (See section Updating Blink for more information). See Section 5. Powering Blink for available power configurations.
2. LED: This provides feedback to the user during operation, as well as for firmware updates. See section LED Status Indicator for an explanation of the different LED indicators.
3. Port 1 (2.5mm stereo audio): This port accepts the Wired Remote or other custom trigger. The Wired Remote is used to turn Bink's WiFi On/Off, as well as provide LED feedback during operation.
4. Port 2 (3.5mm stereo audio): This port is used for Motion Detector Schedules and can be used with our X-Band Motion Detector accessory, or another 5V trigger signal such as a PIR sensor. (See section Motion Detection for more information). *Do not connect anything other than the motion detector cable into this input!*
Blink is equipped with an RGB LED which provides the user with a full range of feedback. Below is a list of each LED flash type and what they represent.
During the firmware update, the LED will follow the pattern below
Blink will need to be powered differently depending on the model revision and camera you are using
If you have a Blink with a black case, you can choose the following power options:
If you have a Blink with a white case, you only have one option:
Blink is programmed entirely through a WiFi interface. In order to connect to Blink's WiFi signal, follow these steps:
NOTE: Some phones and computers have WiFi settings that will automatically connect to a known WiFi network with the strongest internet signal rather than staying connected to Blink. Since connecting to Blink's WiFi network does not provide external internet access, some devices will not stay connected. You might need to temporarily adjust the WiFi settings or remove any saved networks in the area for the period required to set up the new shooting schedule of Blink.
Blink flashes the LED blue once every 5 seconds to indicate that WiFi is on and can be connected to. Once Blink is setup, WiFi can be turned off to conserve power. This is done by plugging in a Wired Remote and holding the button down for 3 seconds. The LED will flash cyan twice to indicate WiFi turned off and will no longer flash blue every 5 seconds. Pressing the Wired Remote button down for another 3 seconds will flash the LED cyan three times and turn WiFi back on.
NOTE: After 15 minutes, WiFi automatically turns off to conserve power.
The following outlines the key features of the powerful Blink web based User Interface (UI).
A. Firmware Version: Displays the firmware version of Blink. CamDo support may ask for this information in the event of a support request.
B. Camera Status: Status information such as the camera type, battery level, and remaining SD space are displayed here. By default, these will show ‘-’ at startup until Blink establishes communication with the camera. Note that this information is only updated when the camera is turned on by either synchronizing the camera time (firmware v2.00 or later), a schedule or the Manual Test Controls.
C. Time and Schedule Status: Camera Time is the time Blink has established with the camera. Next Interval displays the time for the next upcoming schedule, where the schedule# to be activated is contained within the brackets (#). After the Next Interval displayed has passed, you will need to refresh the browser to display the current Next Interval scheduled.
D. Sync Camera Time: Clicking the Sync Camera Time button will push the local device time to the GoPro camera making it very easy to keep the GoPro time up to date. If Camera Time is ever different from the local time, click Sync Camera Time to update Blink and the GoPro camera with the devices local time.
E. Manual Test Controls: The Manual Test Controls drop down provides a way of manually controlling the camera. These controls are typically only needed to test that the camera is communicating with the Blink.
F. Save All/Clear All: Clicking Save All will store the settings for all 10 schedules to Blink. Important: Be sure to click this if any changes are made to the schedules. Clicking Clear All will reset all 10 schedules to their default settings.
G. Schedule 1-10: These are the 10 Schedules which determine when and how the camera will be controlled. Each schedule can be hidden/revealed by clicking on the drawer. Each Schedule is comprised of a Time Window, Day Selector, Mode, and Action. Setting these 4 elements will fully define what the camera will do and when it will do it.
H. Enable: The Enable button toggles the schedule. Blue means the Schedule is active and will trigger the camera at the defined intervals. The drawer on each Schedule also turns blue as a quick way of determining which Schedules are active.
I. Time Window: Choose when the start and end times for when the Schedule is active.
J. Day Selector: Choose the days of the week for when the Schedule is active. Blue means the day is chosen.
K. Mode: A Schedule can be set to Intervalometer or Motion Detector. If set to Intervalometer mode, the user must input an interval for how often the Schedule will repeat within the time window. If set to Motion Detector mode, no interval is needed because the motion detector will determine when the schedule is triggered.
L. Action: A Schedule can have one of three actions, Photo, Multishot, or Video. If Video is selected, be sure to set the length in seconds or minutes. Be sure to set the particular camera settings (resolution, frame rate, etc) you require in each of the modes that you select as these settings will be used.
Blink has the ability to setup a scheduled email notification every day*. In order to use this feature, Blink must be near an active WiFi network. This notification will send the following information:
To enable this notification, click the checkbox to expand the settings. Input the WiFi settings as well as the email address you wish to receive notifications on. Adjust the time as desired, then click Save All.
A sample email notification is displayed below:
Blink Email is a feature added in the Blink firmware v2.02.00. If the "Enable Email Notifications" checkbox is not displayed in the Blink User Interface, make sure your Blink is running firmware version 2.02.00 or newer. The Blink firmware version can be seen in the top right corner of the Blink User Interface and the Blink firmware can be updated by following the process shown here.
Starting in Blink firmware v2.02.00, our Blink Email service will ensure that the camera time remains accurate by re-syncronizing the clock with an MTP server each day when Blink is connected to the internet to send the email notification.
*NOTE: Email notifications requires a subscription in order to be activated. CamDo offers a trial subscription of 1 month when you first configure the notification. To obtain the trial, just enter the information in the Blink UI as normal and the device will automatically be entered into our system. Once this trial has expired, you will need to purchase either a 3 month or lifetime subscription.
Certain applications will require the use of scripting for the HERO3+ and HERO4 cameras*. If this is required, click the checkbox as shown in the image below. When scripting is enabled Blink will still turn the camera on based on the scheduled intervals or motion detections. However, Blink will ignore the Action that is selected in each schedule and only turn the camera on since the action will be controlled by the script.
Starting in Blink firmware v2.01, the "Enable Scripting" checkbox is removed and scripts will be triggered using the "Camera On" Action with a time of 0seconds. This will work like the previous Scripting Mode by only turning the camera on with no end timer since the camera should be turned off via the script on the SD card.
Blink can be controlled with a Motion Detector schedule to only capture footage when triggered by an external signal between a set time of day to capture wildlife or act as a security camera. Blink's Port2 (3.5mm stereo audio input for motion detection) can be used with either a sensor with digital 5V input/output such as a PIR or Accelerometer (not sold by CamDo) or our X-Band Motion Sensor (purchased separately).
When a Motion Detection schedule is active (See 7 Setting up a Schedule for more info), the camera will turn on and process the selected action any time it registers motion. If the Action is Photo or Multishot, the camera will just take a single image or burst images respectively. If the Action is Video, the camera will record when motion occurs and continue for programmed time 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.
Connect the 3.5mm audio connector to Blink. Then connect the 4 pin header as shown in the image below. The X-Band detects motion facing the opposite side of the sensitivity dial. Note also the mounting instructions below.
The X-Band sensor comes with a sensitivity adjustment dial. On first run, ensure that the dial is turned all the way to the right. Blink is optimized to detect motion with the sensitivity of the X-Band sensor at it’s highest. If you notice the sensitivity is too high, you can dial it back until you find the best setting for your project.
The X-band sensor ships with a high quality 3M velcro strip on the detector side, which can be used to mount the sensor such as inside one of our weatherproof outdoor enclosures. Choose your mounting position, remove the protective covering and stick it down. Make sure it is oriented in the direction of detection as per the image above. The X-band uses 10.5 GHz microwave signals that will pass through thin glass and plastic (but not metals) with very little signal attenuation, so it can be mounted behind a window or inside our weatherproof enclosures.
As of firmware version 2.01.00, Blink is also compatible with PIR sensors and external interfacing. This means that a schedule can be programmed to accept an external input to trigger an action.
The PIR/External selection will trigger the camera based on a digital high/low signal that can be provided by common PIR sensors, where high (+3.3V to +5V) indicates motion has occurred. Unlike the X-Band which requires a set amount of pulses within a certain timeframe, PIR/External mode only requires a pulse for more than 250ms. See this blog post for more details.
Blink's port 2 is designed to power an external peripheral/sensor and react to signals generated by that peripheral/sensor. The connections to port 2 (3.5mm stereo audio jack) and an example circuit connection are shown below:
Blink's Port2 only supplies power when a Motion Detection schedule is active. +5V @ 100mA can be drawn from the Tip connection of Port2 to power the peripheral only if USB power is supplied to the mini USB port on the side of Blink. If USB power is not supplied, 10mA max can be supplied to Port2 from the GoPro battery alone.
The Signal pin (Ring connection) is internally protected, but care must still be used to prevent damage to the input transistor. Acceptable range is +3.3V to +5V to the trigger signal pin.
This is a beta feature that can be found in v2.00.00 of the Blink firmware. It has since been removed due to instability, however it can still be accessed here. This feature keeps the camera on when the schedule is active and turns it off when the schedule has finished. This allows the camera to take images and record video instantly when movement is detected since Blink doesn’t have to wait for the camera to turn on or off in between motion detections. Be wary of the added power consumption when using this mode!
Occasionally CamDo will release updates for Blink to improve performance as well as unlock additional features. Follow this procedure to ensure Blink is updated properly. The current Blink firmware version is indicated in the top right corner of the Blink UI. To ensure you have the most up-to-date firmware, click here.
Note: The USB flash drive must be using the FAT32 file format to be able to perform the Blink firmware update and Blink does not support partitioned drives or other formats. The FAT32 file saving format is the default format for PC and used with most USB flash drives under 32GB. Large capacity flash drives might be using the exFAT format which is not compatible with Blink. If you are using a MAC, the following link explains how to format a USB flash drive to FAT32.
Once the Blink firmware has been updated from a version previous to v2.02, the schedules and logs must be cleared from the web interface.
DELETE LOGSbutton to clear the log file.
CLEAR ALLbutton to reset all schedules to the default settings before re-programming your desired schedules.

Additional Blink Troubleshooting information can be found here.
When Blink encounters a problem, an entry is saved into the Blink Error Log. You can access the Blink Error Log when connected to Blink's WiFi and using your webbrowser to navigate to the URL: http://192.168.1.1/log.html or by clicking the Error Log link at the bottom of the standard Blink programming UI. Information on the Blink status codes is located here.
What happens if there is a conflict between schedules?
If multiple schedules have been set and there is a conflict between them, priority is given to the lower numbered schedule. For example, schedule 1 has priority over schedule 2.
