We now have limited stock of the Naked Time Lapse Intervalometer which is suitable for older cameras. If you are using a Hero3+Black/Silver of Hero4 camera, purchase the all-new Blink, which has the same features and more!

The CamDo Time Lapse Intervalometer for GoPro cameras is a programmable intervalometer designed for taking long time lapse sequences. The Intervalometer allows the camera to be turned off between capturing time lapse images.

The Intervalometer turns the camera on at programmed intervals so that the GoPro can capture an image or video before turning the camera off to maximize the battery life. In most cases, the camera will take about 700 images on a single battery charge (2,000 on the HERO2). These images can be spread over hours, days or even weeks without recharging the battery.

It is a small high quality circuit board that plugs into the HERO Port on the back of the GoPro camera. The Intervalometer is small enough to fit inside the GoPro HERO3 Frame Mount or the extended back doors provided with the GoPro accessories such as the GoPro LCD BacPac or the GoPro Battery BacPac. 

NOTE: HERO4 compatibility can only be achieved through a custom firmware modification to the camera. The firmware modification is explained in detail here.

You are strongly advised to use an SD card from the recommended list on GoPro's website. Use of cards not on the list, especially SanDisk Ultra cards, will greatly increase your chance of trouble with your setup.
  • Programming Flexibility

    • Programmable delayed start
    • Automatic Start mode turns on the camera a few seconds after remote power up (all compatible cameras except the HERO4 Black)
    • Repeat cycle or continuous operation once started
    • Programmable repeat cycle from 35 seconds to one week or more
    • Programmable on time from 12 seconds to infinity
    • Programmable scripts can be used to take a photo or video on each cycle.

    No Additional Battery Required

    • The Intervalometer uses the camera’s battery. In standby it uses very little power (similar to a watch) and does not reduce the battery life.
    • Because it requires no power source and fits inside the waterproof housing, it can be used in any environment the camera can handle.

    Suits Your Needs

    • The Time Lapse Intervalometer is available encased in a rugged acrylic enclosure.

    * HERO4 compatibility can only be achieved through a custom firmware modification to the camera. The firmware modification is explained in detail here.

    With the current GoPro firmware, the Intervalometer can turn the HERO3 Black, HERO3+, and HERO4 cameras on, but it cannot turn them off. The camera must be programmed to turn off after taking a photo or shooting a video of the desired length using scripts which are installed on the SD card. This allows for considerable flexibility in deciding what the camera will do when triggered by the Intervalometer. Sample HERO3+ and HERO3 Black scripts can be seen here. HERO4 scripts are structured differently, and their feature set can be seen here.

    Scripts are not required for HERO2 or HERO3 White cameras.

    Setting Up Your Time Lapse Intervalometer

    Frequently Asked Questions

    How long will the battery last if I shoot some number of photos per hour?

    Calculating battery life is non-trivial. It depends on the camera model, firmware version, SD card speed, lighting conditions, battery size, age of the battery, ambient temperature, and more. To help you understand the issues and to calculate estimated battery life, consult the Camera Power Consumption Study and our Time Lapse Calculator.

    I want to shoot a 4 minute video of a 4 month construction job. How do I do that?

    You want each month to be one minute of video. That is about 2 seconds per day, or 60 frames at 30fps. Shooting 24 hours a day, that is one shot every 24 minutes, or about one shot every 10 minutes if you only care about the daytime (acquiring shots for daytime only can be done using our Programmable Scheduler or by removing nighttime shots during post-production). Program the Intervalometer for one shot every 10 minutes. At 144 shots per day, the internal battery will last almost 2 weeks. A 32GB SD card will hold 5-10,000 shots, depending on the complexity of the picture, and the resolution selected. You can put 35-70 days on each card.

    So much for theory. In practice, things go wrong. The camera can stop working. The battery might not have been fully charged. The SD card may have a flaw. A bird dropping might block the lens. We never recommend leaving the camera unchecked for more than a few days. Always assume that what can go wrong, will go wrong. Use two cameras to get different angles and to provide backup if something happens to one camera.

    I only want to shoot from 9 to 5, Monday through Friday. How can I best do that?

    Our Programmable Scheduler product is designed for that purpose. It is easy to set up to capture image at certain times, or to enable time lapse captures on a specific schedule.

    Are custom versions of the board available?

    Yes, we can provide modified versions of the firmware at our regular consulting rates. We will do our best to provide you with the solution you are looking for.

    Does the Intervalometer retain its settings when I remove it from the camera?

    Yes, the settings are stored in flash memory and will be retained until you program different settings or do a factory reset.

    Does the Intervalometer board fit inside the waterproof case?

    The Intervalometer does not fit in the housing shipped with the camera. It fits in the extended backdoors provided with the GoPro accessories such as the GoPro LCD Bacpac or the GoPro Battery BacPac.

    The Controller fits in the GoPro HERO3 Frame Mount, which comes with 2 frames, one for the camera alone, and one which holds the camera and BacPac accessories, such as the Battery BacPac and the CamDo Time Lapse Intervalometer. Be careful, if buying on eBay, where you might not get both together.

    Another simple way to secure the camera and Controller board in the standard case for use indoors or in good weather, is to use an O-ring or a rubber band to hold the camera in the case with no backdoor. Pictured is an AS568-134 O-ring which fits nicely.

    Outdoor Weather Resistant Enclosure

    CamDo now offers an Outdoor Weather Resistant Enclosure designed to house the Time Lapse Intervalometer or other CamDo controllers along with space for a high capacity battery.

    Can a solar panel or AC power source be used to extend the operating time?

    The cameras can be powered by external batteries charged from a solar panel or other suitable power source. See the Operating Manual for more details.

    The CamDo Solar System includes a solar panel, high powered lithium battery, and a weather resistant enclosure.

    Can I download images via USB while using the Intervalometer?

    Yes, this works very well with the HERO3. A long USB cable can be permanently connected to the camera. Plug the USB cable into a computer and wait for the scheduler to turn the camera on. The images can now be moved from the SD card to your hard drive. When you unplug the USB cable from the computer, the camera will turn off. The Intervalometer will resume shooting with the next image. There is no need to touch the camera. The USB cable can be plugged into a charger for longer battery life.

    Does the Intervalometer work with your battery eliminators?

    Yes, we recommend using the Intervalometer with a Battery Eliminator. There is a slot in the back of the Intervalometer for the battery eliminator cable to pass through.

    Using the battery eliminator reduces heat from the camera battery and charging circuit. A battery eliminator also bypasses the problems that some users have had with the GoPro charging logic when charging from the camera’s USB port causing the camera to freeze and require a reset.

    I am a not a hacker. I have an idea for a project for our organization. Can you help?

    Yes. The Intervalometer board was originally designed to handle custom projects we built for scientists and professional photographers. It is very flexible and can be reprogrammed to respond to different kinds of control inputs. It also has an optically isolated output which can be used to control lighting, or give different types of feedback. Contact us for a quote for your application. Our rates for custom firmware are very reasonable.

    I know how to write code for the MSP430 processor. Can I reprogram the chip with my own firmware?

    Yes. The SBW interface is brought to the edge of the board, so you can use the Texas Instruments Launchpad ($4.30) to program the device. There is a tutorial: Use your launchpad as a programmer. Let us know if you come up with something really brilliant!

    What do our customers use our Intervalometer for?
