TrustedReviews posted a review of the Axis Communications 207 Network Camera

The 207 is only for indoor use and is equipped with the same 1/4in progressive scan RGB CMOS sensor as the 206. However, low light handling has been improved as the 207 can function down to 1-lux as opposed to the 4-lux of its compatriots. Note that as light levels decrease the camera will automatically switch from a colour to a mono image. Frame rates don’t see any improvement but they are still very good as the camera can deliver 30fps at all seven resolutions.
