Instructions for updating e3vision camera firmware


  1. Make sure cameras are not in active use (“stop write” and “disconnect streams” in the dashboard)

  2. (≥ v0.3.0) Unbind from the cameras requiring a firmware update.

  3. Download the newest version of Watchtower software appropriate for your platform. You will be updating the firmware from the new version of Watchtower.

  4. Download the newest version of firmware e3v-firmware-signed.fw and put it inside the same directory/folder as the Watchtower executable e3v-watchtower(.exe).

  5. Open up Watchtower and go to the maintenance menu (expand System -> Maintenance)

  6. Check all cameras, click “Send Firmware”, and watch for “Firmware successfully transmitted.” in the console log before moving onto writing. This process should take 5-10 seconds.

  7. When transmit finishes, click the next “Flash Firmware & Reboot” button. Do not interrupt camera power at this time and wait for “Firmware flashing complete; executing reboot.” This process should take 40-60 seconds.

  8. (< v0.3.0) If you must run an older version of Watchtower, you may need to trigger a reboot manually with the “Reboot” button or by unplugging and replugging the camera.

  9. The first boot after new firmware should take 20-40 seconds until cameras are ready, depending on your network setup.

  10. Re-ping the cameras, and verify that the new firmware has been installed using the "Firmware Version" button. Bind with the cameras to begin use!
