The Aiphone JF-DV vandal-resistant surface-mount audio/video door station works with an Aiphone JF Series master station (sold separately) to enable remote communication with visitors prior to authorizing access to the building. The station includes a 1/4" color camera that sends live video feed to a master station when a visitor presses the illuminated call button. A white LED illuminates the visitor area to brighten the video feed in low-light environments.The cast-zinc faceplate, metal call button, and clear polycarbonate lens cover are vandal resistant. The station mounts to a single gang box using an Aiphone MKW-P mounting plate (sold separately) or directly to a wall using the included mounting hardware.
