We’ve been working with our video platform partner by reducing false speeding alerts caused by temporary roadworks speed signs that stay in the system after the signs have been removed.
As a result, Digicore is making a temporary change to how cameras handle speed signs across our fleets.
Quick summary
- What’s changing: Cameras will no longer “remember” speed signs for an extended period after they’ve been seen.
- What stays the same: Cameras will still detect speed signs in real time and raise speeding events when vehicles exceed the limit.
- Why we’re doing it: To reduce false speeding events from temporary / roadworks signs that have been taken down.
- Who it affects: All Digicore-connected dash cameras using our video / ADAS platform.
- Can this be reverted? Yes – if you need the old behaviour, contact Support and we can discuss your configuration.
What was happening?
Our cameras use multiple methods to understand the speed limit, including:
- Reading speed signs through the camera (ADAS)
- Using additional information that can allow signs and limits to be “remembered” for a period after the sign is seen
In practice, this meant that:
- When temporary roadworks or reduced-speed signs were in place, they could be remembered for up to two weeks, even after the physical signs had been removed.
- During that period, vehicles could be flagged as “speeding” in the system, even though the road had returned to its normal limit.
For customers, this showed up as false speeding events and noisy reporting, especially on routes with frequent roadworks.
What are we changing?
To reduce those false events, Digicore is:
- Disabling the “memory” function for speed signs that relies on crowd-sourced information, across all Digicore fleets.
- Keeping real-time camera-based speed sign detection (ADAS) ON – so when the camera sees a sign, it still updates the limit and will still trigger speeding events if the vehicle stays above it.
In plain terms:
The cameras will still react to the speed signs they actually see, but they will stop remembering those signs for long periods afterwards.
This is being applied fleet-wide as a temporary measure while our provider works on a better way to manage how long these signs are remembered.
Why is this a temporary measure?
Our request to the platform provider was to shorten the memory window (for example, from around two weeks down to a much shorter period).
They’ve advised that changing this behaviour across all regions and road networks is a complex, long-lead change, and will take time to implement properly.
As an interim solution, they have:
- Disabled the crowd-sourced speed sign memory, which is the part most likely to cause incorrect limits after temporary signs are removed.
- Left camera-based speed sign detection active so speeding events can still be detected based on signs that are visible.
Once a more refined approach to “speed sign expiry” is available, we’ll review and may re-enable a shorter, smarter memory period – and we’ll update all customers before we do.
What does this mean for your fleet?
In day-to-day use, you can expect:
- Fewer false speeding events after temporary / roadworks signs are taken down
- Cleaner reports, with less need to explain away incorrect speeding alerts to drivers or management
- No change to how drivers interacts with the cameras or how you access the platform
Your drivers will still be monitored for speeding based on the signs the cameras see and the limits they detect in real time.
Can we keep the old behaviour?
By default, Digicore is applying this change across all fleets, because we believe it will improve clarity and reduce noise for the majority of customers.
However, we recognise that some organisations may have specific operational or compliance reasons for preferring the previous behaviour.
If your business relies heavily on remembered speed limits and you want to discuss your options:
Please contact Digicore Support or your account manager and we’ll work with you to review your configuration.
