The DDV can be easily and quickly installed to new or existing doors and requires no external wiring or electrical connections.
Once fitted, the battery-operated device works by a simple push button to show a clear, expanded view outside. The digital camera inside the DDV operates via a 14mm diameter hole in the door positioned at comfortable eye level. From the outside it looks similar to the conventional ‘spy-hole’.
The DDV measures 140mm high by 216mm wide and 25mm deep within a neat silver tone frame. Total measurements of the display are 82mm high by 109mm wide.
The units come with mounting screws and require 8 AA batteries.
