Are there also some sort of sensors on the top of stop lights? Or are they usually traffic cameras?

i know years ago in kelowna there were sensors on top of the lights for emergency vehicles - they picked up the flashing/strobing of the activated emergency light bars and would give that direction "green". knowing this came in handy late at night when approaching certain intersections - flash your high beams a bunch and get greens!! ha!
unfortunately, that has changed and now the emergency vehicles have a transmitter that sends a out a signal when they have their emergency lights/sirens activated. the street lights receive the signal and change the lights to green for the emergency vehicle. i know this is definitely the case for fire trucks - not sure about ambulance or rcmp.
