Security officers no longer have to be tied to a desk and a wall of monitors when they can view digital surveillance footage on their iPhone or Android while patrolling a facility. A Shadow Series DVR connects with the phones through the free CEC Connect mobile app, which enables multiplex view, image save and PTZ control, along with the ability to search and view live and recorded video, freeze the video, connect multiple devices to one DVR and save multiple DVRs in a built-in address book for easy connection and on-the-spot investigations.
