Mobile surveillance cameras ­ensure best first response

August 2015 CCTV, Surveillance & Remote Monitoring, Integrated Solutions

Surveillance has perhaps been the most significant legacy of 9/11. The continuing threat posed by global terrorism has driven huge amounts of government investment into electronic surveillance, as well as both wide and targeted physical monitoring systems in our cities. Digitised mobile camera surveillance in particular presents a powerful weapon in counter terrorism and law enforcement, yet this emerging technology remains relatively undiscovered.

The UK boasts the world’s most extensive CCTV coverage. It is estimated that most individuals are seen by a camera an average of 340 times per day, and in Central London an individual will be on camera about 95% of the time. But compared to the UK, CCTV use in other jurisdictions is limited by a range of fiscal, legislative and privacy constraints.

According to the Queen’s University Surveillance Studies Centre, the likely consequence of camera surveillance is that “crime and undesirable conduct are displaced into neighbouring areas once cameras are installed in a target location.” The centre cited a San Francisco study, which found violent crime decreased within 250 metres of ‘open-street’ surveillance cameras, but increased beyond 250 metres. Crime, like water, finds the gaps and exploits them.

Filling those gaps is critical, and the introduction and use of new mobile camera technology has been heralded as the solution.

Mobile and body worn cameras

Mobile and body worn cameras have been traditionally used for the same purposes as static CCTV: deterrence and evidence. But it has been issues around use of force, such as the 2014 shooting of Michael Brown in the St Louis suburb of Ferguson, and the need to protect both police and civilians that have intensified calls for police to be wearing Body Worn Vest Technology (BWV). It has been recognised that the behaviour of both parties changes when a BWV system is involved.

The first empirical study on the use of body cameras by police was released last December by researchers at Cambridge University’s Institute of Criminology. The results from this 12-month study of California’s Rialto Police Department indicate a 59% drop in use-of-force by officers wearing BWV and an 87% drop in complaints against officers.

And quite simply, if police and security personnel were not recording their actions in responding to an incident, then an onlooker with a smartphone/device would undoubtedly be recording their actions. According to the US Office of Community Oriented Policing Services, “given that police now operate in a world in which anyone with a phone camera can record video footage of a police encounter, body-worn cameras help police departments ensure events are also captured from an officer’s perspective.”

“Whether we decide to roll [body worn cameras] out more widely across the organisation is not a decision we are going to rush,” commented Inspector Ian Geddes of Victoria Police via email interview. “Further work is needed to help us to consider the next steps”, he stated, “including considering the outcomes of other body worn camera trials happening across Australia and the world, as well as the ongoing considerations around evolving technology and data storage needs.”

Indeed, it is the evolving technology that is making law enforcement and security procurement of body worn cameras increasingly complex. While many organisations have trialled and implemented solutions based on transparency, evidentiary and behavioural benefits, emerging second-generation technologies are enabling cameras to do much more. The major consideration is now around whether to invest in cameras that can also provide live video feeds, immediate remote response and intelligent analytics aimed at early warning and intervention.

Gaps in first response

Traditional static CCTV and remote monitoring systems have been limited in providing first responders with real-time information when responding to suspicious events and or intercepting crime in progress. The majority of video surveillance systems are reactive in nature, in that they record the pictures delivered by video cameras on streets, which are later analysed for evidence or explaining crimes and other incidences. CCTV has been very effective, for example, in the hunt for Boston Marathon bombing suspects, but was of no value in preventing the incident.

Even when remote monitoring systems send alarms in real time to security monitoring centres, they are often poor in quality and require the attendance of a security response vehicle to investigate. According to Luke Percy-Dove of Matryx Consulting, “A very high percentage (95%) of all alarm traffic is associated with false alarms, meaning most alarm attendances are a waste of time too.” Typically Police will not attend an alarm event unless it can be validated or the premises carries a high level of priority. “And remember, if 95% of all alarm events are false, why would they?”

Digital, or ‘second generation’ technology incorporating video analytics can turn existing technology into a proactive system. This allows alarm-receiving centres to make decisions with real-time information, in many cases removing the need for security officer call-out. This results in a significant reduction in costs and false alarms, leading to improved security and proactive responses to situations as they occur.

Once a first responder is deployed to an incident site, however, they still depend on radios to relay information back to central monitoring stations. In most jurisdictions, this includes police, who are unlikely to have anything other than radio with which to communicate while on foot. According to Percy-Dove, this means that whoever is in charge of coordinating the response needs to rely on words to understand the situation on the ground. “In this day and age and with the technology available”, he states, “it’s crazy it still happens this way, but people don’t know better and what is possible.”

Some first responders have the option of sending images from a car or transmission hub to the control, but this is limited by the necessity of being in close proximity to the hub. “As we all know, when a police officer is dealing with a situation they are not necessarily near or anywhere close to a car or hub,” comments Imran Aziz of safety and security solutions provider Xtralis. “Also, these units will not be able to provide you with GPS information for use with mapping software.”

Additionally, Percy-Dove notes, “some vehicles are now being fitted with video capability, but as far as I know these are recorded only in the vehicle and are not yet broadcast back to the station.” In the case of the Victoria Police, Supt Geddes concedes that not all police vehicles are mobile data network enabled.

First responder solutions

BWV technology incorporating live-streaming CCTV can provide the potential answer to the real-time intelligence deficit of radio-only communications from first responder to base. “I think it adds real value because at street level you get to a whole different perspective of what has happened,” states Percy-Dove, “… the key is always to get the best possible information you can.” But it only works if it is plugged into a system that can transmit audio and video in real time to command and control structures so that the intelligence can be analysed and operational decisions made.

Entering the marketplace are a number of innovative solutions for early and reliable detection, remote visual monitoring for immediate and effective response. The City of London Police (CoLP), for example, has recently commenced a trial of an Xtralis solution that provides live transmissions from police vehicles and BWV to better assess situations and more efficiently deploy appropriate assistance.

According to Imran Aziz, the Xtralis HeiTel body worn solution has the ability to use multiple types of cameras with the same unit. The recording unit is remote from the camera, so if the camera is pulled off the vest by a member of the public the recording remains safe on the vest, thus protecting the evidence. It also possesses a live streaming capability and GPS tracking. Xtralis’ WCCTV Nano technology allows first responders to live stream wirelessly via 3G/4G, LTE and CDMA, as well as satellite, Wi-Fi and broadband networks. Its software allows multiple vests to be monitored at any given time, “giving the commanding officer complete situational awareness”.

The HeiTel mobile technology is also used in other mobile applications such as public transport, cash in transit vehicles, and rental equipment and vehicles. “In principle the car unit will do everything the BWV will do, but in addition it can have up to 10 cameras on the unit, connect to panic buttons, blue light engagement, and audio systems to name a few,” says Imran Aziz. “In Europe, Xtralis developed a self-contained mobile early fire detection solution called RapidProtector, which utilises the HeiTel mobile technology combined with a compact area smoke detector to create a temporary mobile smoke detection solution for control rooms and base stations. It can be used during construction and upgrades when conventional fire panels need to be switched off.”

In Australia local councils, water and electricity authorities are looking towards mobile video-streaming technology to protect assets and people in areas where there is no traditional network infrastructure available.

Water authorities are using the technology for use in pump stations or near dangerous drainage systems to proactively prevent unauthorised access. Used in combination with alarm sensors, a central monitoring station can be alerted when unauthorised persons enter a protected area, and an audio warning may be issued to the intruders in order to remove the threat.

Rob Galic, sales director at Xtralis says “Local councils are using the technology for health and safety to protect rangers who are driving in remote areas, and for protection of parking officers.” According to Galic, it’s also being used by tow truck companies whose drivers are often the target of aggression by vehicle owners when their cars are being towed from illegally parked areas.

Solutions such as these are making traditional mobile CCTV look archaic, and presenting law enforcement, public transport and security procurement departments with the choice between a deterrence and evi­dentiary tool on the one hand, versus all that and a whole lot more on the other.

In essence, it is a choice between a tool that can record a criminal act and a tool that can proactively prevent one. Given the increasing political, social, financial and human cost of crime and the continuing spectre of terrorism, the latter option is difficult to ignore.
