LF2/2+ is an all in one solution -- it is a projector that has a camera built into it. The LF2/2+ projector's throw ratio is 1.2 and the brightness is 1,000 lumens. We recommend this solution for small scale installations and indoor spaces like home offices and retail displays.
LF2/2+ has a minimum focus distance of 1.0m (3.3ft), and the throw ratio is 1.2. As an estimate, in bright ambient light, it can scan scenes up to ~6 feet wide and in a dark room, scenes up to ~12 feet wide.
The extra USB/HDMI ports on the LF2/2+ are not functional and should not be used (e.g. you can't plug in two projectors, use the audio jack to feed sound into your project, or plugin a USB drive or another camera/etc.) We also caution against plugging in your phone (e.g., to charge it).
