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 Blink'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_update.bin. If you have ongoing issues please contact CamDo customer support.
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* to provide peace of mind that the system is online and working. The Blink Email service will also ensure that the camera time remains accurate by re-synchronizing the clock with an NTP server each day when Blink is connected to the internet to send the email notification. In order to use this feature, Blink must be near an active WiFi network with internet access. 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:
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.
*NOTE: Email notifications require a subscription in order to be activated. CamDo offers a trial subscription of 2 weeks 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 12 month CloudX-Lite subscription. Assigning a CloudX subscription to your device is outlined in our CloudX User Manual.
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!
Blink has a set of stereo audio ports that can be used for custom interfacing to lights, micro controllers, or other devices. Below outlines the outputs for the interfacing ports of Blink.
This section is for advanced users. You will void any warranty with improper connection to the interfacing ports of Blink.
The port 1 (2.5mm audio jack) of Blink is used to trigger the Blink's WiFi signal by closing contact between the ring and sleeve for 3 seconds and typically used with the included wired remote. - See the Connecting to WiFi section of the manual for details.
The port 1 of Blink input does not require additional voltage from the remote for triggering the WiFi signal. The remote only closes contact between 2 input wires. Therefore, the button remote can be replaced with a microcontroller or any trigger capable of closing the contact between 2 input pins.
When the GoPro camera is turned on by Blink, the port 1 is driven high to 3.3V 5mA between tip and sleeve. This output can be used for feedback on the status of the camera or for triggering an external device when the camera is on such as a flashlight.
The port 2 (3.5mm audio jack) of Blink is used for triggering the GoPro from an external sensor/input. - See the Motion Detection section of the manual for details.
The X-Band motion detection mode is only for use with our X-Band Motion Sensor. When a motion detection schedule is active in X-Band mode, Blink detects pulse frequency from the X-Band Sensor to determine if motion has occurred. The PIR/External motion detection mode allows for Blink to be triggered from other sensors with a digital high signal output between +3.3V to +5V to the trigger signal pin. The trigger signal can be provided by closing contact between tip and ring as shown in the diagram above. When a motion detection schedule is active in PIR/External mode, Blink will trigger the camera when the signal input is pulled high between ring and sleeve for more than 250ms.
When a motion detection schedule of Blink is active, the tip of port 2 is driven high to output 5V with a maximum 100mA if connected to an external USB power supply, or a maximum of 10mA if powered from only the GoPro battery. This output is typically used to power a motion sensor, but can also be used to trigger an external device between set times of day as programmed using a motion detection schedule. Be sure to pull the signal pin low to prevent false triggering when you are only using the 5V output.
Although the ports of Blink only output a low power signal, a "solid state relay" or a "MOSFET circuit" can be used as a power switch using the trigger signal provided by the Blink's low current outputs to supply power from a high current/voltage source. The switching circuit can be connected between the power source and the external device while only closing the circuit to supply power to the device when Blink is providing the trigger signal. The Sparkfun MOSFET Power Control Kit is one of many simple boards with a RFP30N06LE MOSFET capable of switching up to 60V at 30A using a low-current trigger input from our controller boards.
NOTE: Connection of custom circuits to the interfacing ports of Blink is for advanced users only! You will void any warranty with improper connections to Blink.
