This Weldex mullion camera is built to mount inside a door or window mullion (the narrow vertical frame between glass panes), giving it a slim profile suited to entrance and access-control monitoring where a standard camera body won't fit discreetly. It uses a Full HD CMOS sensor with wide dynamic range for clear images in the high-contrast lighting typical of doorways and vestibules, and PoE power lets it run on a single network cable without a separate power run, which keeps installation costs down. The housing finish is chosen to blend with the surrounding door or window hardware. Model WDP-84ML2M-WT specifically ships with PoE powered, white housing, 2MP resolution.
