I agree with both PastorJim and littlearrow. There's nothing out there really to compete with those 2 higher end Reconyx. Everything else will have the Blurrrrrrrr even at 10 mph in IR. I don't own one but if it says it will catch a plate at 50 mph, I'd bet it does. Their rep is so good, I'd also bet you would get a refund if its doesn't do as advertised.
I just watched the sample video from the link... WOW. That is pretty amazing. The SM750 Demo vid has made me a believer.
Man, just shows ya the crap we buy from the box stores. And yes, I can buy 3 of mine for 1 of those. But I'm not trying to catch a plate.
Good Luck
