CCTV and Public Safety

Zooming in on a new era

SEIZING THE CCTV OPPORTUNITY
IN PUBLIC SERVICES

Combining the power of CCTV and emerging technologies to realise the future vision
of preventative policing.

The presence of close-circuit television (CCTV) cameras in public and private locations has long been a fact of life for citizens in many countries.
For public safety agencies, these devices present a useful way to collect, monitor and analyse information that can help to keep the public safe and prevent and detect crime.

But the reality is that their usage to date has only scratched the surface of the potential benefit they could deliver.

Today, rapid technological advances—both in cameras themselves and wider digital capabilities—are opening up new ways for CCTV and digital surveillance to benefit public safety.

CCTV TODAY: WHAT’S BLURRING THE PICTURE?


To harness the potential of CCTV to help create this future, public safety agencies first need to overcome three key issues with today’s CCTV systems.

The need for horizontality

The first is that most public safety CCTV operations remain focused on reactive processes. CCTV cameras now boast many advanced features, and the video footage they capture is usually recorded and archived – but is only subjected
to analysis if warranted by reports of an incident, after the event. There’s a stark contrast with the social media sentiment monitoring conducted by many organisations – both public and private sector – which is increasingly comprehensive,
AI-enabled, detailed and real-time. This means the CCTV device remains largely a “black box”, producing data that’s only pulled out from the archive for review after the event if something has happened.

The need for agility

The second – related – issue is that manual interventions still tend to dominate CCTV operations. A lack of automation means that most real-time monitoring and supervision of CCTV content is still carried out by teams of humans sitting in control rooms, watching content and monitoring other sources such as sound sensors, and then reporting back on what they’re seeing and hearing to determine what the public safety response should be.

People are also used to conduct post-incident analysis, trawling through many hours of footage and sound recordings from different cameras and sensors to establish what happened.

This approach is slow and resource intensive, with the result that the time-lag between an incident taking place and
a human accessing and reviewing the footage can be hours, but more likely days or weeks. This means the current approach is barely feasible for an agency covering a major city – and will become less so in the future, as more video sources come online from the likes of transport networks, shopping centres and citizens’ own video recordings.

The need for a secure method

The third challenge for today’s public safety CCTV systems is that their ability to share data across functions or other organisations is very limited.

The ability to transfer video evidence seamlessly between different public safety agencies and other participants in the ecosystem delivers many benefits.

These include dramatic time saving and better intelligence from bringing disparate footage together. But historically CCTV information has been stored in discrete network video drives or on physical tapes or CDs, meaning sharing it is difficult, slow and highly labor-intensive. Taking a large city as an example, this issue is underlined by the sheer range of CCTV systems likely to be operating at once – owned and run not just by police, but also by local authorities and transport operators on the public service side, as well as by citizens, third party operators and facilities management companies on the private sector side.

All of these systems can produce data that could benefit public safety if shared in a controlled and permissioned way.

A lack of automation means that most realtime monitoring and supervision of CCTV content is still carried out by teams of humans sitting in control rooms, watching content and monitoring other sources such as sound sensors, and then reporting back on what they’re seeing and hearing to determine what the public safety response should be.

COMPLICATING FACTORS

Citizens’ Rising Expectations

It’s vital that the police retain the public trust and confidence that enables them to work effectively with the communities they serve, something that greater use of CCTV could threaten if the public regards it as excessive. At the same time citizens’ expectations of the public safety benefits that can be achieved through CCTV are rising rapidly, driven by Hollywood movies and their own experience of using ever more advanced home surveillance and security systems based on smartphones.

But changing attitudes to CCTV are also highlighting current blind spots around capabilities and ethics related to:

  • The ability to differentiate between friend and potential foe;

  • The trust relationship between citizens and their government;

  • Susceptibility to manipulation or "adversarial techniques".

THE WAY FORWARD

AI, Automation, and Shared Cross-Agency Insights

Major changes are now needed if CCTV’s full potential for public safety is to be realised. These changes must include using digital technologies to cut across the silos that currently separate CCTV from other sources of relevant data. Equally importantly, agencies must make a concerted shift towards “smart surveillance”—enabling a small number of human analysts to monitor a wider range of cameras and detection sensors. This is achieved by using AI, automation, video analytics and technologies like “machine vision” to analyse video streams in superhuman detail in real-time, providing alerts and predictive insights that would be beyond the abilities of any human to see or develop.

CCTV video data needs to become just one element in a comprehensive range of information that’s brought together and integrated from a wide array of stakeholders in a holistic public safety platform.


A PUBLIC SAFETY PLATFORM INCORPORATING CCTV

FIVE FUNDAMENTALS FOR THE FUTURE OF CCTV


Moving from today’s largely manual and siloed CCTV systems to the future we’ve described might appear to be a daunting journey. But public safety agencies can navigate it by focusing on five fundamentals:

1

Do some housekeeping

Carry out a review to understand the current state of the CCTV system, all the way from the technology capabilities of the existing cameras to the back-end processing of images.

2

Use the power of AI and machine vision

Compare the capabilities of current CCTV systems with the improvements in public safety that could be achieved through advanced cameras (if not yet being used), and implementation of technologies like automation, AI and machine vision in the back-end.

3

Privacy and ethical responsibility is paramount

While identifying the use cases, always remaining mindful of the need not only to meet legal requirements, but also to act responsibly and be sensitive to citizens’ concerns over privacy. This is vital for “taking the public with you” and sustaining citizens’ confidence and trust.

4

Think platforms, not siloes

Design a scalable data platform to support collaboration and information sharing, initially emphasising high-impact use cases that will deliver the biggest benefits to public safety, and building support, buy-in and momentum both across the organisations involved and among the public. At the same time, identify how CCTV video data can be integrated, stored and analysed in combination with the full range of agency data.

5

Collaborate across the ecosystem

Reach out to other agencies, wider organisations and the public to encourage them to agree to share their video and other data on the platform, opening up opportunities to expand the available information and the benefits delivered over time.

CCTV in public safety currently presents a huge but largely untapped opportunity for public safety agencies—not only to detect crime, but to drive the advance towards a more preventative role in protecting the public. It’s time to realise its potential. The five fundamentals above can help them do it.
