Hi everyone. Firstly thanks for the time everyone puts into this forum! I've used it previously to gather advice based on others' cases and successfully challenged an unfair PCN. This one I'm less sure about, but having read several similar but not identical 53J cases on here I'm interested in opinions about my case.
The council PCN states that on On 15/01/25 I drove down Telferscot Road SW12 0HW at 09:06, contravening a no entry restriction that's in place from 08:15-09:15 (I believe due to a school on the road). Location:

The Council evidence is CCTV footage which shows my car entering the road and passing the signs.
I had a look at the online legal docs outlining the restriction and it all looks correct to my layman eye. The order is a written doc with a supporting map. There's an online portal to view traffic restrictions which is actually pretty good, kudos to the council:
https://streets.appyway.com/lambethThe reason I'm thinking about challenging the PCN is because of signage. When approaching the road, the signs showing the restriction are parallel to the road you travel on before turning into that road, making them harder to spot:

If you enter from the bottom of the road, off Emmanuel Road, they've helpfully put signs that are perpendicular to the direction of travel which are more visible:

They also have the same signs, perpendicular to the direction of travel, on nearby Scholars Road which has the same restrictions.
However where my car entered the top of the road, from Burnbury Road no equivalent sign is in place. This is where the sign would be, on the post with the CCTV camera on it:

I'd welcome thoughts on whether you think there's reasonable grounds to challenge here, or if it's unlikely to be successful. Thank you in advance!
