    No. They are talking about the speedometer in your car, not the GPS.

    And even with the speedo, it doesn't mean that you would have been going slower, just that you might be. Legally, a speedo must not show a lower speed that you are actually travelling, but can show a higher speed, within the tolerances FarFetch explained, so manufacturers will calibrate them with that in mind. 

    So, if you had looked at your dashboard and your speedo was reading 49 mph, you could be fairly confident that you *weren't* doing more than 49.

    The dashcam will be using GPS to work out your speed based on where your car was each time it 'pings' the satellite - so  it's closer to an average speed check, although it's averaging it over very short periods so ought to be fairly accurate except if you were accelerating or decelerating sharply - so if you were doing 55 but slammed the brakes on and went down to 30  when you saw the police camera it might register a speed lower than 55. How accurate it is will depend on factors such as speed, (it's more accurate at higher speeds), signal quality etc.  If it is a built in system it may also 'talk' to your car to increase accuracy.
    Update - I went out in my car earlier and drove at 30 mph (digital clock). I then plugged in the dash cam and watched the footage back. It said I was travelling at 28-29 mph .
    So I’m guessing this means that my dash cam when it’s said 49MPH would be wrong, and that I was travelling faster :(

    Does anyone know how long it takes for a speed camera to focus onto you before it gets a reading?
    I have gone past a couple of local digital clocks near me, one shows around 28mph when I am doing 30, the next one, literally less than 100m away, always flashes angrily showing 30 - even when I have deliberately slowed to around 27mph on my speedo.

    Another one I know of I cycle past regularly, my bike GPS pretty much always matches the speed shown on the display unit within about 0.5mph e.g. showing 22 if I am doing 21.5-22.5 on the GPS

    If your dash cam showed 49, your speedo, could in the worst case scenario of poor calibration, have been showing 60.15mph based on the 110% overread + 6.25mph - I would suspect if you could somehow safely test the digital displays, to get it to show 49 to match the GPS, you would probably be doing around 55 on the speedo
    Oh S**T! I hope that is not the case!! No doubt very soon I’ll have something in the post notifying me what speed I was doing

    @Arsenal2019

    I’d imagine you’ve probably gone through every conceivable scenario in your head since your thread starter;...perhaps best to just sit it out now (before your brain gets too mashed!) and see what actually transpires. I know that’s sometimes easier said than done.

    My son got a speeding  NIP in 2019 (39 in a 30 zone);...the offence was committed Saturday afternoon and NIP received Tuesday morning, so they were pretty quick off the mark;...not sure if all areas are as keen though, especially given the current situation.

    You’ve probably got a tense few days ahead of you, but whatever transpires don’t put yourself through the wringer any more than you need to.

    Yeah welll you’re definitely right about that! Genuinely don’t think I’ve stopped thinking about it and that’s not an exaggeration. I got caught Saturday afternoon myself too!
     yeah like you said, I’ll find out soon no doubt. Just got to sit tight

    Good. Maybe it’ll teach you to pay attention and slow the hell down.

     Almost 50mph in a 30 zone is unforgivable.

    You're at the moment now when it could go either way for you. As an ex cop I would expect the process be issued within a couple of days. First class post. So you would normally receive your NIP within a week. Of course the law allows up to 14 days. Are you the reg keeper as that will alter things relating to time?
