This indoor micro dome is high quality aluminum construction, and less than 2" in diameter. The high-resolution, low-light camera makes for a very professional installation into drywall, paneling, ceiling tile, and even wood, or plastic. The camera picture is extraordinary with built-in image-enhanced technology. Pinhole lens makes the unit virtually undetectable. The extremely small size makes this camera the best for "when looks matter".The viewing of the dome can easily be adjusted.
