What are these cameras please?
Discussion
They do not detect cars and are not the same as radar detectors you get at temporary signal sites. They detect pedestrians and assist in the phasing/timing of the signals. Like the detectors under security lights people have in their driveways. Their official name is "Above Ground On-Crossing Pedestrian Detection Systems". They will only be found at pedestrian crossings.

That link is not accurate for the vast majority of UK signal-controlled junctions. JustLiam85 said:
Stevestrange, how come they are pointed to the path and road?
Because they detect peds - they generally won't allow the signals to give a green light to cars while they detect a pedestrian on the crossing. They also aim at the path so that they can (attempt to) reduce the instances of someone pushing the ped demand button, and then walking off, making traffic stop unnecessarily, but that's not as reliable for some reason.

Just found that one - that might be a red light camera, because if you go back in time to 2020 on streetview you can see a "traditional" red light camera outside the school that isn't there now. It's a bit strange though, as it's facing the junction and not aimed at the line. You would usually expect the camera to be able to get the car crossing the line, and in most cases be able to see the red light at the same time. It doesn't look like any speed cameras I've ever come across. I think it's more likely to be speed monitoring or parking enforcement for the school.
