Each door latch/lock may be selected to suit the individual door so that it engages into the eCam.
Variants of eCam include no-status-indicator, status-indicator-included or with-status-indicator-and-automatic-unlock in case of power failure.
Supply voltage required is in the range 9-32V and emergency opening is facilitated by means of a bowden cable mounting kit if required.
A video of the eCam operation can be viewed at here.
