Hhmmm...I did some more searching on this, and I found a couple of reviews on the V1.

The following link for e.g. suggests that the Escort 8500 was the best in detecting photo radar and the V1 was second. So I guess it does detect photo radar.

Problem is the StealthOne is $200 over and above the price of the V1...
