There is nothing new about this at all, it seems to be making the rounds on forums and e-mail fowards quite a bit lately for some reason and the info is false.
The boxes were tried in Edmonton way back when I was living there still (I think it was 2005-2006?) but they decided not to use them after that. Strathcona County, which I'm sure is using the box in the photo, is actually scrapping the portable photo radar boxes for uniformed cops after using them for over 10 years.
The e-mail going around reminds me of this one:

edit: Found an article. Definitely not new.
