Photo speed cameras are trivially easy to beat. They use a continuous (as opposed to operator triggered) doppler radar. Any decent radar detector will reveal their presence.
ta delenda est
B&W cameras are sensitive to IR. Not so much with color. I frame grabbed an image of a soldering iron with a Sony Exview.
I hate IR sensitive cameras. More often than not, digital cameras (which are IR-sensitive) register IR as blue, which makes some really bizarre colored incandescence. Like this guy's camera:

To show you that you aren't perfect.
My understanding, supported by multiple web citations, is that the power level of such devices is perhaps 100X LOWER than conventional speed radar, since their necessary range is limited to photo-capable range.
I note that radar detectors are available that include GPS and a ROM listing of fixed photo radar site locations... updated by regular subscription ;-)

Perhaps the best tool to use then, is the "computer" between your ears. .
I prefer to keep my eyes firmly on the road and the traffic around me. At the speeds I drive I prefer not to be distracted looking for signs ;-)

Well then, you are making your choices and taking the consequences. I still recommend choosing such that you have the spare power to process for the warning signs. .
Is this spare enough...

Yes, very much so. They'll show up a remote control LED or lit cigarette very brightly.
That's because they usually have IR rejection filters.
