The 4L was designed to cover larger CCTV domes – including the new Verkada CD53 and CD63 models. The tough 3 mm polycarbonate allows cameras to be deployed in sensitive areas where safety, security, and protection is a priority, reducing ligature risks. The 2mm microphone holes mean your camera can keep recording audio without any interference.
