@larbiamma@gmail.com you need to do two things:
1) Call TFL on 0343 222 3333 and ask for the video, they will send a DVD in the post and put the penalty on hold while you wait. Until we know what the video shows, we don't know the strength of TFL's case.
2) Send this to foi@tfl.gov.uk:
Dear Transport for London,
There is a CCTV camera outside 85-87 Lee High Rd, London, SE13 5NS, which is visible here: https://maps.app.goo.gl/sxDmH5cWax5m6Yyh9
I would like to request the make and model of the camera please.
Also please provide any documentation confirming the make and model of the camera.
Yours faithfully,
Assuming you do this before 5 pm on Monday, put a reminder in your calendar to chase up TFL for an FOI response on 28 December.
