powerstation explained :
Can anyone recommend a reasonably priced security camera that can produce a
reasonable quality picture at night under streetlights ?

You need to look for a camera with IR capabilities, usually those at
the cheaper end will be black and white. The performance of the none
commercial ones might still not be that good under sodium lighting, but
depending upon your proposed use - you might be able to improve the
performance by using an IR lamp.
