Chester Zoo has grown rapidly since its foundation in 1930 so that today it is spread across more than 125 acres, and is home to more than 15,000 animals and 500 different species. It attracts more than 1.9 million visitors each year - making it the most popular UK visitor attraction outside London.

 With further growth planned, Chester Zoo began a site-wide vulnerability assessment, led by the zoo’s then head of security, Nigel Peers, out of which flowed a series of recommendations for modernisation of the zoo’s security.

Zoo security requirements

The Zoo needed a fully-integrated and networked camera system to enable the security team to spot and act on all threats faster; tighten perimeter security; improve visitor and staff health & safety monitoring; and support keepers in assuring the welfare of the animals in their charge.  

The new system needed to be centralised to support the fully-professionalised security patrolling team. However, video also needed to be distributed effectively to enable health & safety officers, keepers and researchers, to view specific sets of camera images when necessary. All this was only possible working in close partnership with IP video specialist systems integrator NW Systems Group.

Improving image quality and coverage

NW Systems, once on site, initially discovered that many of the legacy CCTV cameras were generating poor images.  NW Systems replaced approximately 60 faulty CCTV cameras with new Axis network cameras. Meanwhile, all remaining CCTV cameras were networked using AXIS M7016 and M7014 Encoders, alongside all new network camera transmissions. A total of 160 new Axis cameras were installed and networked by NW Systems across the original or ‘core’ zoo, The Islands and elsewhere, together providing much more comprehensive coverage site-wide.

AXIS P3225-LVE cameras were installed in numbers across The Islands, partly because of their versatility and robustness making it possible to site them both inside and outside animal enclosures. 

Special attention was paid to siting of cameras for total discretion. Where surroundings required, camera housings were camouflaged, thereby offering highly unobtrusive surveillance. In addition, the newly centralised control room was fitted with the very latest video management software (VMS) from Milestone Systems.

Tightened security at main entrance and car park

NW Systems also provided increased coverage across the recently renovated Jubilee Quarter, the Zoo’s main entrance and large car park serving it. It also installed several Axis Q6000-E PTZ Dome Network Cameras, alongside Axis C3003-E Outdoor Network Horn Speakers, clamped onto existing lighting masts throughout the car park.

This enables the Zoo’s security team to monitor activity around the 1000-vehicle capacity car park, for the protection of visitors and their belongings. The loud speakers can be used to transmit live messages to arriving visitors to guide them towards the entrance and to deter any potential wrong-doing.

Animal welfare and keeper safety needs

NW Systems was also called in to help solve a specific concern of the Zoo’s Lead Elephant Keeper, associated with opening large gates to let the elephants out of the Elephant House into the wide-open habitat and back into the elephant house at night.

The existing remote door control system was now supported by high quality live views provided by five-megapixel AXIS P1357-E network cameras covering the doors. These same cameras were also being used to capture the magical moments of elephants giving birth to their babies – three baby elephants have been captured on these cameras over the last 18 months. The video sequences were shown live via the Zoo’s website and recordings have been also been kept for marketing purposes.

Rationalise, network and centralise security operation

Over a three-year period, working in close partnership with the UK’s largest visitor attraction outside London and largest zoo in the UK, NW Systems has helped Chester Zoo to rationalise, network and centralise its security operation, underpinning the professionalisation of the Zoo’s security team. NW Systems has also provided the right platform for distribution of high quality video images to meet zoo keepers’ specific operational and research needs.

The new system also now supports keepers’ animal welfare and behaviour research requirements - helping them to spot and discourage inappropriate visitor interaction with animals. It provides vital evidence in case of any incidents which might result in insurance claims.

Potential threat identification

From a security perspective, helping the Zoo’s security team to identify potential threats more rapidly – using video images to brief patrolling officers on where to go and what to anticipate on arrival. The system enables the security team to assess and prevent escalation of any threat by moving rapidly and effectively to the scene and then, once there, acting in a way that is proportionate with a pre-identified threat. The new IP video system also supports post-event follow-up - including supplying timely, high quality video footage to the Police when necessary.

The result is a state-of-the-art IP camera system which transmits video from nearly 300 Axis cameras to a modern, IP-based centralised control room. It also offers the potential to deliver live and recorded video to patrolling officers’ mobile devices on the ground when the time is right. Vanderbilt networked intruder alarms have also been installed by NW Systems to further protect key buildings around the site.

"Chester Zoo now has a video security platform
which is highly reliable, expandable and future-proof"

Beyond standard security surveillance

Nigel Peers, Security Manager, Chester Zoo, summarised: “Chester Zoo now has a video security platform which is highly reliable, expandable and future-proof. We know that whatever our requirement in terms of intelligence, video analytics and integration with other physical security systems such as intruder alarms or access control systems; it’s possible to bring it all together with our new IP video system displayed in the Zoo’s new security control room. Speed and appropriateness of response to threats is now assured.”

Frank Crouwel, Managing Director of NW Systems, added: “I’m very proud that we’ve been able to work with Chester Zoo every step of their three-year journey to upgrade and harden their physical security provision; while also creating a camera system which supports many other operational requirements from visitor and staff health and safety, to animal welfare and behaviour research, as well as retail management and loss prevention.”

Gareth Simpson, Head of Site Operations at the Zoo said: “I’m very pleased that we selected NW Systems to help transform our security provision, working alongside our Security Manager Nigel Peers and the rest of my team.

They’ve been highly responsive and sensitive to our unique, multi-dimensional needs which go way beyond standard security surveillance: using cameras for everything from visitor and staff safety, animal welfare monitoring and behaviour research studies, right through to meeting and exceeding tightening Crowded Places terrorist-threat mitigation requirements and supporting the Police with any enquiries. NW Systems is a great long-term partner for us.”

Artificial intelligence: why you should enable deep learning and video analytics
Artificial intelligence: why you should enable deep learning and video analytics

Constantly optimising deep learning algorithms yields better video analytics performance, even in complex applications such as facial recognition or in scenarios with variable lighting, angles, postures, expressions, accessories, resolution, etc. Deep learning, a form of artificial intelligence (AI), holds the potential to enable video analytics to deliver on long-promised, but not often delivered performance. Our AI series continues here with part 2. Adapting existing hardware Today, low-cost system-on-chip (SoC) camera components enable deep neural network (DNN) processing for the next generation of intelligent cameras, thus expanding the availability of AI processing to a broader market. AI software can even add learning capabilities by adapting existing hardware to AI applications AI software can even add learning capabilities by adapting existing hardware to AI applications. Today’s smartphones include cameras, gyroscopes and accelerometers to provide sufficient data to drive AI applications. Software can adapt existing hardware to transform them into AI devices capable of continuous learning in the field. Inside a video camera, real-time deep learning processing can be used to detect discarded objects, issue loitering alarms and detect people or objects entering a pre-defined field. Data capture form to appear here! Detect anomalous data Additional capabilities are applicable to demanding environments and mission-critical applications, such as the perimeter protection of airports, critical infrastructures and government buildings, border patrol, ship-tracking and traffic-monitoring (e.g. wrong-way detection, traffic-counts and monitoring roadsides for parked cars: all vital video security solutions). IoT is transforming the lowly security camera from a device that simply captures images, into an intelligent sensor that plays an integral role in gathering the kind of vital business data that can be used to improve commercial operations in areas beyond security. For example, cities are transitioning into smart cities. Deep learning enables systems to search surveillance footage, to detect anomalous data, and to shift surveillance from post-incident response to providing alerts during, or even before, an event. The ability of deep learning for video analytics is much more sophisticated and accurate Make critical decisions Deep learning can eliminate previous video analytics limitations such as dependence on a scene’s background. Deep learning is also more adept than humans at discerning subtle changes in an image. The ability of deep learning for video analytics is much more sophisticated – and accurate – than the programmed approaches previously employed to identify targets. AI is a timely solution in an age when there is more video surveillance than ever. There are too many cameras and too much recorded video for security operators to keep pace with. On top of that, people have short attention spans. AI is a technology that doesn’t get bored and can analyse more video data than humans. Systems are designed to bring the most important events and insight to users’ attention, freeing them to do what they do best: make critical decisions. Multiple camera streams AI can reduce information overload to enable humans to work with the data more efficiently The video benefits reflect the larger goal of AI to amplify human skills. AI can reduce information overload to enable humans to work with the data more efficiently. Another benefit is faster search, and new systems make searching video as easy as searching the internet. AI enables specific people or cameras to be located quickly across all the cameras at a site. Searching can be directed by a reference images or by physical descriptors such as gender or clothing colour. Consider a scenario of a child missing from a crowded shopping mall: Every second can seem like hours, and artificial intelligence and neural networks can enable a rapid search among multiple camera streams using only one photo of the child. The photo does not have to be a full-frontal passport-type photos; it could be a selfie from a party as long as the face is there. Intrusion detection scenario AI can find her and match her face from among hundreds of thousands of faces captured from video, in nearly real time. AI can also continuously analyse video streams from the surveillance cameras in its network, distinguishing human faces from non-human objects such as statues and animals. Privacy concerns are minimal as there is no ID or personal information on the photo, and the image can be erased after use. And there is no database of stored images.    In a perimeter security/intrusion detection scenario, an AI-driven video system can avoid false alarms by easily distinguishing different types of people and objects, e.g., in a region set up to detect people, a car driving by, a cat walking by, or a person’s shadow will not trigger the alarm. Part three coming soon. If you missed part one, see it here.

3 key security tips for public event planners
3 key security tips for public event planners

Public spaces in cities and suburbs are important places for community development and promoting outdoor recreation. These areas may include main streets, parks, promenades, band shells and fields. Such locations are often utilised by public event planners for community activities, including summer festivals, wintertime ice skating rink installations, music concerts and art fairs. As the year draws to a close, holiday and Christmas markets as well as major New Year’s Eve events, present cities with constant public event security needs. The public nature of these events increases risks of incidents with high-speed vehicles that put attendees in danger. Fortunately, there are three ways for public space managers to prevent casualty-causing collisions and further promote the use of local public areas. Developing an effective action plan    When strategising how to react to an alert, think about what time of the year and time of day the event is occurring It is important to have a plan developed before an incident or accident occurs. Warning systems, utilising doppler radar and digital loop technologies, alert guards to abnormal vehicle velocity changes in the surrounding area. Managers of public areas should organise a meeting with public safety authorities and local agencies to discuss what must immediately occur when a high-speed vehicle is approaching a public event. When strategising how to react to an alert, think about what time of the year and time of day the event is occurring. Having such a reaction plan in place combines technology and strategic planning to ensure everyone is on the same page to effectively target a threat and promote overall event safety. Securing public areas  Ideally, there will be no need to implement a well-conceived action plan. After all, taking preventive measures to secure public areas where events take place is important to keep people safe from accidental vehicle collisions and intentional attacks. Protect attendees by clearly separating pedestrian and vehicle locations using security devices such as – Barricades Portable barriers Bollards Install guard booths  Avoid the risk of vandalism and theft, making sure people are safe when walking back to the cars at night by keeping parking areas illuminated with flood lights. Install guard booths with employees who monitor activity in the parking area and who are prepared to react if an alert is triggered. Furthermore, prevent accidental collisions by clearly marking the parking area with informative warning signs and using barricades to direct traffic. These three tips can be used by public area managers to promote security at the next community event. Additionally, the technologies used to secure an event can also be used as infrastructure for year-round security. Installing gates that shut when the public space is closed or using aesthetically pleasing bollards are steps any public area manager can take to promote community safety.

Choosing your security entrance installation in line with your company culture
Choosing your security entrance installation in line with your company culture

The extensive analysis and discussion preceding any decision to implement a new physical security solution – whether it’s hardware, software or a combination of both – often focuses on technology, ROI and effectiveness. When it comes to deciding what type of security entrances to install at your facility, you will almost certainly also consider the aesthetics of the product, along with throughput and, if you’re smart, you’ll also look into service concerns. Each of these factors has its important place within the evaluation process, and none should be overlooked as they all have a significant effect on how well your entrances will perform once they are installed. Culture influences door solution decisions How significant will the change from current entrances to security entrances be for employees? Still, one additional factor actually trumps everything: if you have not considered your organisation’s culture in choosing a security entrance, you may be missing the most important piece of the puzzle. Culture is a part of every other decision factor when selecting an entry solution. Before you make a decision about what type of entrance to deploy, you need to consider and understand the values, environment and personality of your organisation and personnel. For example, how significant will the change from current entrances to security entrances be for employees? If people are accustomed to simply walking through a standard swinging door with no access control, this will be a culture change. Beyond this, whether you are considering a type of turnstile, a security revolving door or possibly a mantrap portal, simply walking through it will be a significant change as well. Training employees on door security You’ll want to know whether employees have ever used security entrances before. If these types of entrances are in place in another part of the facility, or in a facility they’ve worked in at an earlier time, the adjustment will not be as great as if they’ve never used them at all. Consider, too, how your personnel typically react to changes like this in the organisation or at your facility. They may be quite adaptable, in which case there will be less work to do in advance to prepare them. However, the opposite may also be true, which will require you to take meaningful steps in order to achieve buy-in and train employees to properly use the new entrances. With the increased importance of workplace security, discussing new entrances with  workforces will help maintain a safer environment Communicate through the decision-making process All of this will need to be communicated to your staff, of course. There are a number of ways to disseminate information without it appearing to come down as a dictate. Your personnel are a community, so news about changes should be shared rather than simply decreed. As part of this process, you’ll need to give some thought to the level of involvement you want for your staff in the decision-making process. Finally, do not overlook the special needs among your personnel population. You undoubtedly have older individuals on staff, as well as disabled persons and others who bring service animals to the office. Entrances need to be accessible to all, and you never want to be in the position of having a gap in accessibility pointed out to you by the individual who has been adversely affected. New security entrance installation By communicating early and often with your personnel, you can alleviate a great deal of the anxiety Once you have made the decision about which security entrances to install, training your personnel on how to use the new security entrances – both before and after the installation – will help to smooth the transition. Because workplace security is such a big issue right now, it makes sense to discuss the new entrances in the context of helping to maintain a safer environment. They will prevent violent individuals from entering, decrease theft, and most of all, promote greater peace of mind during the workday. If you can help them take control of their own safety in a responsible way, you have achieved much more than just a compliant workforce. By communicating early and often with your personnel, you can alleviate a great deal of the anxiety and concern that surrounds a significant change in the work environment. Schedule group meetings Consider your employees; what type of communications do they respond best to? A few suggestions to educate staff on the benefits of the new entrances include: Typically, you would communicate a general message 2-3 months in advance and then provide more specific information (for example, impacts to fire egress, using certain entrances during construction) in a follow up message closer to the installation date. Schedule group meetings to: announce the rationale for increased security, share statistics on crime, review the new security changes that are coming, show drawings/photos of the new doors/turnstiles, and show the orientation videos available from the manufacturer. These meetings are an excellent way to work through user questions and directly address any concerns. Once the installation of a new security system is complete, it is a good idea to have an "ambassador" on board to help employees use these new systems Ensure you monitor public areas If you are implementing a lot of new changes, such as a new access control system, new guard service and security entrances, you might consider hosting a ‘security fair’ on a given day and have the selected vendors come for a day with tabletop displays to meet employees and answer questions during their lunch. This could be a great way to break the ice in a large organisation. Make user orientation videos (provided by the manufacturer) available in several ways, for example: Intranet Site Monitors in public areas—lounges, cafeteria, hallways, etc. Send to all staff as email attachments Immediately after installation, once the doors or turnstiles are operational but before they are put into service, train ‘ambassadors’ on how to use the door/turnstile. Have these people monitor and assist employees during peak traffic times. What is the ultimate success of the installation? By communicating clearly and openly with your population you can greatly facilitate adoption and satisfaction If you have thousands of employees, consider dividing them into groups and introduce the new entrance to one group at a time (Group A on Monday, Group B on Tuesday, etc.) to allow a little extra orientation time. Place user education ‘quick steps’ posters next to the door/turnstiles for a few weeks to help employees remember the basic steps and guidelines, e.g., ‘stand in front of the turnstile, swipe badge, wait for green light, proceed.’ Ask your manufacturer to provide these or artwork. While there are always going to be people who are resistant to change, by communicating clearly and openly with your population you can greatly facilitate adoption and satisfaction. Your responsiveness to any issues and complaints that arise during and after the implementation is equally fundamental to the ultimate success of the installation.
