Security Camera Text Verification

The following surveillance camera images were taken by request from a customer that wanted to know if our security cameras were capable of reading the text on a soda can from 2 to 3 feet away.  This customer needed to use our surveillance systems for an application that required text verification.

This test was done using a Geovision DVR system and a box style color security camera with 470 lines of resolution and a 6-60mm varifocal lens. The security camera was placed 2 feet away from the soda bottle ad about 1 foot higher.  Sample video was taken with the lens adjusted with a wider view (approximately 3mm), then zoomed in to approximately 12mm to read the text close up.
