All the cars in the intersection is snapped.

the camera should snap you twice which means there should be 2 flashes.
The first snap will tell how far into the intersection when the light turned red.
The second snap will indicate how far you've moved away from the first snap.
They will determine if they will issue a ticket from these 2 pictures.

Probably the car behind you ran the red and triggered the sensors before the ped xing and got you into the picture.

Redlight ticket is $271+ 1 point on driving record.

fine can be reduced by going to court pleading guilty. Point can be erased by going to traffic school IF you haven't been issued to traffic school within the past year. OR if you don't have time for court(couple hours of waiting at least), you can hire a lawyer to go to court for you.
forgot if you have to go to traffic school if you hire a lawyer.
