# Performing Overlapped Acquisitions

A Task can also be configured to perform overlapped acquisitions when a Camera Device is set to be triggered via a hardware device. In this scenario, the Camera will continue to acquire images while the Task is running; each image that is acquired while the Task is running will be queued in the CogAcqFifo. As soon as the Task completes its execution, it will run again, based on the next queued image. The Task will execute once for each ImageAcquire Event that has occurred.

In this scenario, it is important to ensure that the Task processing time is, on average, faster than the amount of time between images. In addition, the $Devices.<CameraName>.NumReady tag is useful in determining how many images are waiting to be processed.
