1. A system for training usage of a firearm, comprising: an end unit comprising an image sensor, the end unit positionable against a target having a bar code deployed proximate thereto, the image sensor having a lens defining a field of view of a scene that includes the target, and the bar code storing encoded information including spatial information related to the target defining a target coverage zone; a processing subsystem operatively coupled to the image sensor; and a control subsystem operatively coupled to the processing subsystem and the end unit, and remotely located from the end unit, wherein the system is configured to selectively operate in a first mode and a second mode according to a control input from the control subsystem, and wherein in the first mode the end unit is actuated to scan the bar code to extract the target coverage zone, and wherein in the second mode the image sensor is actuated to capture a series of images of the target coverage zone and provide the captured series of images to the processing subsystem, and the processing subsystem is actuated to analyze regions of the captured series of images to determine a strike, by a projectile of the firearm, on the target, wherein the strike is determined by comparing one of the images of the captured series of images to at least one other one of the images of the captured series of images to identify a change between the compared images.
