Here's a photo of one in Underhill Road. The problem with thinking you can avoid the cameras is that you don't know you've been fined until a few weeks later when the PCN arrives and if you did the same journey several times, several PCNs can arrive at once and give you a very big shock. If you set up auto-pay with TFL, then you pay ?10 instead of ?12 and if you get caught on camera without knowing it, at least you won't get a PCN.
