Technology FAQs

What data can you provide?

Vivacity can provide historic, real-time and predictive data on the road network, this includes fully classified counts, speed and path analysis.

How does it work?

We use the latest artificial intelligence techniques in order to detect and classify objects of interest in video feeds. Each of our sensors contains a camera and a processor. On board the sensors, we deploy artificial intelligence to detect and classify road users. These detections are converted into useful data feeds, for example counts of vehicles along a road, paths of cyclists across a road, or numbers of passengers on a crowded platform. We transmit the useful anonymous data to the cloud, and delete the video on the device.

How does it identify different types of vehicles?

We train our systems to identify different vehicles by providing them with hundreds of thousands of images, containing different vehicle types. Much like a child, they use these examples to learn the features of different vehicles, such as vans having no back windows and sometimes (but not always) writing on the sides; that bicycles are thinner and more transparent than motorbikes; and that vehicles with two rows of windows are probably buses. Combining hundreds or thousands of features together, they can identify each type of vehicle, just like a human.

Where is the video processed?

In most projects, we deploy our sensors. These have on-board processing capabilities, so our artificial intelligence algorithms are run on the sensor, extracting the data we need – and then discarding the video itself. However, if you have an existing CCTV network, we would just tap into that and post-process the video feeds to avoid duplicating hardware.

What do I need to provide for you to install a sensor?

All our sensors need is a lamp post or similar structure which can take the weight of a couple of pigeons, and a power supply.

What happens if I cannot provide permanent power?

We have deployed our systems in many places with centrally switched lamp columns, where there is only power to the lamp column at night, and have developed a battery solution to mitigate this. If there is no power available at all, we would usually deploy solar or wind power solutions, although this tends to become more expensive.

How can I access the data?

We have a web dashboard which allows you to analyse and interrogate data from any sensor. You can also quickly and easily download the data in a variety of formats, or request a different format from us if required.

In addition, we provide automated access to our data through modern, industry-standard JSON APIs. This allows developers and systems integrators to work with our data quickly and easily.

Technology is moving quickly. How do you avoid your systems getting out of date?

Every sensor can be remotely updated quickly and easily. Given that artificial intelligence algorithms get better and better with more data, we update most of our sensors on a regular basis to ensure that everyone is using the latest and greatest technology available.

Ethics and Privacy Q&A

These are cameras. Should I be worried about my privacy?

Not at all. We have built this system using data protection by design principles – under normal operation, our sensors gather no personal data whatsoever.

Is this GDPR compliant?

Yes, absolutely. We have tested every element of our system under GDPR principles, and our lawyers are confident that we go “above and beyond” what is required by GDPR.

How does this compare to CCTV in terms of privacy?

CCTV captures images 24/7, and sends them back to a control centre. For comparison, over 99.9% of the time we discard all video footage within seconds. The 0.1% of cases relate to remote maintenance activities and in these instances captured images are blurred on the sensor ensuring no personal data is available to anyone through our system.

Occasionally we need to collect a few minutes of un-blurred footage from a sensor for the purpose of developing and testing new improvements to our software. We will only ever do this if there is a clear and obvious sign at the location of the sensor indicating that this process might be undertaken. If you cannot see a sign, our system is not producing any personal data.

How expensive is it?

We are proud to be bringing new technology to road transport, and want to ensure that this technology is available as widely as possible. With several different pricing options according to the level of capability required, we are confident that you will experience good value-for-money whatever your budget and requirements.

I’m writing a news article, and would love to interview someone from Vivacity. Who should I speak to?

Please email and someone will get back to you quickly.

How are your sensors powered?

Our sensors can be powered from any local AC or DC source.

In some cases, power may be unavailable at certain times of day, for example, some street lighting columns are unpowered during daylight hours when the lights switch off. In these cases, we can provide a small battery pack which powers the sensor during the day and charges up when power is available.

As a producer of industrial batteries under the Waste Batteries and Accumulators Regulations 2009, we (Vivacity Labs) produce lithium ion batteries and are obliged to take back free of charge, waste industrial batteries supplied to an end user for treatment and recycling. If any of our customers require us to take back waste batteries, they should email us at

We will agree the necessary arrangements for the return, proper treatment and recycling of the waste industrial batteries.
