Videos have long been used by law enforcement to investigate crimes and bring criminals to justice. But searching through video recordings for evidence takes a lot of time and resources. Increasingly however, technology is being used to assist police in the analysis of video evidence, while at the same time avoiding any negative impact on civil liberties.
In any major city there are thousands of CCTV cameras which record the lives of the people. While most cameras are owned by businesses and residents, many are owned by the public sector – the police, transportation authorities and local government. There are over 400 cameras in London’s King’s Cross St Pancras station alone. Millions of hours of video footage are produced every day by CCTV.
This video footage is used for many purposes, including potential hazard detection in industrial premises and crowd management for reasons of safety and efficiency.
collecting evidence of crimes
The police also have a large amount of video footage while investigating crimes. In any one case, thousands of hours of video may be available for inspection – much more than what is actually tested.
This is a big problem for the police. Evaluation of video evidence is very difficult in practice. Playing video recordings alone can be problematic because there are so many different formats. And once the video is playing, individual police officers are allowed to “keep their eyes on” the video record for hours. Distractions and lapses of concentration can mean that important clues have been missed.
As the use of CCTV grows, more and more videos become available for investigation. Police forces are inundated, and it is estimated that only 1% of video evidence can ever be examined. In a case involving the murder of a 12-year-old girl in Queensland, Australia, police had more than 21,000 hours of video to investigate – a task that could have taken a man 15 years to complete without the aid of technology .
How does technology provide solutions? Smart video analytics tools like SeeQuestor’s post event The solutions use computing power combined with machine learning and artificial intelligence to extract “noise” from video records, enabling law enforcement to focus on parts of the video that may produce evidence.
This technique does not eliminate the need for human examination of evidence. It only cuts down to a manageable amount that should be scrutinized. This frees up police officers to work on reducing crime and increasing public safety.
In addition, by providing strong evidence for criminal prosecutions, technology can also be used by defense teams to ensure that people accused of crimes have a fair trial. Everyone has a right to justice and a correct record of events can help in getting justice.
real time monitoring
Policing is not the only use of this smart video technology. It can also be used to monitor video in real time. It is virtually impossible for a security officer to effectively monitor half a dozen (or more) TV monitors.

These alerts give security teams time to identify and, if necessary, arrest persons of interest, spot suspicious pieces of luggage without sight, flag and locate persons carrying guns or knives, and monitor incidents as they unfold. and prevent accidents and crimes. They are critically important in many environments: counter-terrorism, traffic control and optimization in smart cities, managing crowds at large events, and spotting danger signals (smoke, movement) in major industrial installations such as power stations.
maintaining civil liberties
This powerful technology naturally causes some to question its impact on civil liberties and privacy in particular. The truth is that while privacy is important, there are other freedoms that citizens have – for example the right to physical safety and life. There are times when privacy is not of paramount importance.
For example, privacy can be attacked under the European Convention on Human Rights (Article 8) if the actions taken are proportionate and necessary and if there is true accountability for those actions. These are important security measures and organizations like SeeQuestor build them into their products to ensure compliance.
The reality is that it’s not the technology itself that’s bothering. If used properly, it can bring many benefits. This is how it is used that needs to be managed. And properly managed smart video technology plays a vital role in keeping society safe by turning unbearable amounts of video data into actionable intelligence.
