Periodic Wake

The Periodic Wake [Ext] [Wake] setting allows the sensor to send a brief half-press (wake) signal to the connected camera or flash equipment at regular intervals. This periodic signal helps prevent certain devices from entering deep sleep modes and ensures they remain responsive for long-term deployments.

Purpose of Periodic Wake

This feature can be useful for a variety of situations, including:

  • Preventing cameras from entering deep sleep or becoming unresponsive if left idle for long periods (for example, some models require a command at least once every 24 hours).
  • Keeping third-party flashes active by preventing them from entering power-saving modes.

Although there are several potential uses, the main purpose of this setting is to maintain camera responsiveness in systems that may otherwise power down or lose connection over extended periods of inactivity.

Setting the Periodic Wake Interval

  1. From the Home Screen, press the Right Arrow until you reach the Periodic Wake screen.
  2. Use the Up or Down buttons to adjust the desired time interval in hours and minutes, from a minimum of 1 minute to a maximum of 24 hours.
  3. Press the Set button to confirm and save your setting.

The interval can be configured in minutes and hours, and the sensor will send a brief wake signal to the connected equipment at each interval.

Enable or Disable the Periodic Wake Function

  • Hold either the Up or Down button for more than 1 second while on the Ext Wake screen.

  • When active, the display will show the “ON” indicator.

Notes

  • Periodic Wake signals are only sent during active time windows. If Time Windows are enabled, wake signals will not be transmitted while the sensor is in an off-window period.
  • If using Camtraptions flashes or cameras that remain active without assistance (which is the majority of cameras), this setting is not required.
  • Using shorter intervals will slightly increase power consumption (not just of the sensor but of the equipment being woken), so choose the longest interval that reliably keeps your equipment awake.
