The screen should be a white projection screen (1.1 gain max) (No silver screen) or flat, non-glossy, white wall. It is best to use a screen with a light-blocking backer material to help from losing light through the back. It is also best to use a traditional vinyl material type screen. Cloth screen material tends to absorb light or allow too much to pass through. The screen should be a 16:9 aspect ratio. If a non 16:9 screen is used the image will just not fill the screen, but will still work. The system is designed to be used on a 8 ft to 12 ft widescreen. A flat wall with no texture painted flat white with no shine to the paint can also be used. It is also important that the screen surface is flat with no waves in the surface for an even image.
As an example, we use the Elite Screens Yard Master 2 in 110" for trade shows.
Projectors for use with our standard 1.6:1 throw camera
(Scroll to the bottom for Short-Throw projectors)
There are many projectors out that will work with our system. The name brands to look for are Viewsonic, Epson, BenQ, Optoma, Hitachi, and InFocus. You will want either an LCD or DLP projector.
Stay away from any projector that says LED (see the warning in red below about LED projectors).
Here are a few projectors that meet our spec as an example.
ViewSonic PX700HD or the newer version PX701HD
Warning against cheap LED projectors on Amazon and eBay:
The cheap LED projectors on eBay and Amazon will claim high lumen output. In reality, these units put out far less than advertised. LED projectors just are not bright enough yet. Most times they will only be around 100 lumens, nowhere near the required 2000 lumens. Stick with projectors that are LCD or DLP and are name brands like Viewsonic, Epson, and Hitachi to ensure you get what you pay for. Here is a great article that talks in depth about false advertising of high lumen output by these types of projectors.
Consider the screen/image size
The system is designed to be set up on at least a 8 ft to a 12 ft widescreen at a 16:9 Aspect ratio. The recommended projector brightness is 2000 to 3600 lumens. But if you have a projector over 3000 lumens projecting a smaller image of around 5 ft to 6 ft or less you may encounter the Screen Too Bright error when calibrating the camera. In this case, you would need to lower the projector's brightness until the calibration will complete. Or alternatively, you can move the projector and camera farther away from the screen increasing the image size.
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 ANSI s to maximum 3600 lumens (depending on screen size, a larger screen needs a brighter projector)
- 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.
Projectors for use with our optional .5:1 Short-Throw camera
This Projector is 1280x800 resolution @3500 lumens and works well with the short-throw camera and matches the throw of the camera at .5:1.https://www.viewsonic.com/us/ps501w.html
Here is another option that is equally as capably as the one above.https://www.optoma.com/us/product/w318st/
This is a 1920x1080 resolution @4000 lumens projector that has a .5:1 throw that matches the throw of the short throw camera.
This projector is 1920 x 1080 resolution @ 3000 lumens and works well with the short-throw camera. But, it has a slightly longer throw at .69:1. While the camera can still sit with the projector, the camera will have more dead space around the projected image. So, it would be more optimally placed in front of the projector at the .5:1 distance for the best performance.
Also, please see our Short Throw setup guide in the below link to familiarize yourself with the specific setup needs of the Short Throw camera.
