This tamperproof, lightweight, all aluminum DVR/NVR box has a hinged front door and a removable rear panel for easy installation and service. The front door is key locked. The compact size of this lock box, 17" in width only, allows it to be mounted in a 19" standard rack using optional mounting brackets. The vented side panels mean that, in most cases, a blower is not required. Available with a 4" cooling fan and power bar (FRE1611).
