Does every camera flash twice?

[ju6121]

I was stupid enough to run a red light last night but the camera only flashed once, does every camera flash twice or do the red light cameras only flash once??

[SS2.]

Two photos allow confirmation that the red light was proceeded beyond and, as such, RLCs normally flash twice (one second apart).

so does one flash mean that im ok or that I have a good excuse if I do get the NIP?

It might mean that you didn't spot the first (or second) flash..

Only time will tell. Wait and see if the registered keeper of the vehicle receives a NIP within the next fortnight.

Cameras will sometimes continue to flash once out of film but often only give one flash instead of two (intended as a warning) - The traffic light cameras are activated by speed in the same way as Gatso's so definately need two pictures. - You never know your luck

Other than the fact that Gatso Type 24 (speed) use radar whereas Gatso RLCs use sensors embedded into the road surface very close to the stop line.

tell you what though, either way I sure as hell am never going to even get close to running a red light again! maybe cameras do work...

I thought they were activated by a vehicle crossing the induction loop beyond the stop line?

What makes you want to run red lights in the first place?

The danger of maybe causing a collision? Or is getting home a minute quicker really that important?

[ju6121]

Neither really, it was one of those moments where hesitated in either braking for amber or trying to make it before red. If I didnt hesitate I would have comfortably stopped or made it before the red.

SPEED cameras need two flashes. A set time apart, distance covered can be measured off pic so enabling proof of speed.

A red light camera only needs to flash once, taking a pic of you over the line, while the light is on red.

What about front facing Truvelo ?

Two photos are taken to show that the vehicle proceeded beyond the stop line with the red light showing.

There's also a few seconds after the light has turned red before the fines start being collected if I remember correctly.

Typically 1 second, give or take a couple of tenths..

The hopelessly inefficient extended red-red overlaps we're suffering these days to create congestion and therefore support the overloaded roads allegations made by the lentilists?

These are pedestrian crossing periods aren't they?

[ju6121]

so why did it only flash once for me? I thought all cameras were digital now and so couldnt run out of film? Or will it only flash once if I crossed Just after the red ( definitely less than a second)

Sorry should have clarified rather than generalised - It was explained to me by an enforcemement officer they do have to determine that the car is moving and not simply overshot the stop line a little, hence they work they work like a speed camera set much slower. I didn't mean to imply they were the same type of internals.
