hi i am urgently looking for a camera with high infrared sensitivity its for a tracking table with the size of 120 (width) x 90 (height) x 90 cm (distance) unlike other multitracking tables (like the reaktable) the ir light has to come from above because we are tracking glass objects but the camera and the projector are located in the table so the six 920nm ir leds (http://www.monacor.de/typo3/index.php?id=84&L=0&artid=5736&spr=DE&typ=full) are 90cm above the surface and the camera is 90cm below the table surface because of this distance the camera needs to be more ir sensitive than mutltitouch tracking solutions with lights from below as daylight filter for the camera i use a 720nm filter it tried several monochrome cameras like: The Imaging Source DMK 21AU04 (http://www.theimagingsource.com/en_US/products/cameras/usb-ccd-mono/dmk21au04) IDS UI-1220ME-M-DL (http://www.ids-imaging.com/frontend/products.php?interface=USB&family=LE&lang=e) Eneo VK-1313/IR 230 V (http://www.eneo-security.com/item/5266/5269/0/103807/index.html) but they are not enough sensitive i had the best results with the eneo camera but its is not getting produced anymore the camera i am looking for needs a cs mount for wideangle objective an shouldn't cost more than 500 euros

thanks in advance for any hints
