My PCN was issued on the basis of CCTV evidence, doesn’t this make it unenforceable?

While the relevant regulations curtail the use of CCTV, generally, there are exceptions; namely, in bus lanes, at bus stops or stands, on school entrance markings and on red routes. At these locations, PCNs may still be served by post. The rules do not provide a blanket prohibition on CCTV enforcement as is widely believed and sometimes reported in the media.
