Within this category of products and devices we focus on audio, sound or voice recorders which can be set to automatically activate if any sound is detected at the target location.

This type of equipment offers the advantage of only recording the action as and when it happens and thus saving the operator having to trawl through hours of non action / dead recordings in order to find the actual recording that matters i.e. when any activity has been detected.
