Currently, the cheapest LED projector we have found that is bright enough is the Hitachi LP-WU3500 for around $2500.
Consider the Throw Ratio
The Throw Ratio is the distance the projector will need to be back from the screen to create a specific size image. Our Tracking Camera has a 1.6:1 field of view. That means you would multiply the width of the projected image by 1.6 to find how far back it would need to be to see the projected image. As an example, an 8 ft wide image would require the camera to be 12.8 ft back from the screen.
Projectors list their Throw Ratio in their specifications as a ratio such as 1.56:1 and usually have a zoom range where that can be adjusted so would be something like 1.55 - 1.73:1. As you can see our camera ratio of 1.6:1 is within this range so this projector would allow the projector and our camera to be located at the same place from the screen.
The minimum specs required for a projector are:
- Minimum 2000 lumens to maximum 3500 lumens (depending on screen size, a larger screen needs a brighter projector) (LED Projectors that will work start at $2500. Cheap LED Projectors are not bright enough)
- capable of displaying a minimum resolution signal of 1280x720 (lower resolution projectors can be used but must be able to read and display at least a 1280x720 signal)
- Proper input (either VGA or HDMI) to match what your PC connector is.
- Warning, you can not connect your PC to your projector with a USB cable. It will not work with the Smokeless Range.
- Warning, signal converters such as HDMI to VGA converters can cause problems. Some may work fine and others may not work correctly.
