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. Housing dimensions are 6-13/16 x 3-7/8 x 1 inches/173 x 98 x 25 mm (H x W x D). (H is height, the vertical distance from the lowest to highest point; W is width, the horizontal distance from left to right; D is depth, the horizontal distance from front to back.)Door intercom systems allow an occupant of a building to communicate remotely with a visitor through at least one door intercom and master intercom. Master intercoms with a door-access button remotely unlock the door for the visitor.Aiphone manufactures intercom systems for residential, business, and healthcare structures.
