Cameras in schools

Security is a top priority in schools throughout the United States. The capabilities of IP video surveillance systems, in conjunction with Video Management Software (VMS) systems, make them one of the most popular and effective security tools available. In this article, Gadi Piran, President, OnSSI defines scope and structure of IP video and its advantages in improving school security in a number of ways including: superior image quality, ease of manipulation, integration capabilities, simple accessibility and a wide scalability range. He adds that IP video systems also allow surveillance cameras to be deployed anywhere within reach of a network connection, while a standards-based design and open architecture ensure the ability to incorporate signals from various types and brands of cameras into a unified video platform.

Video management software (VMS) systems are a central component of IP surveillance that maximise the ability of surveillance cameras located throughout a school campus to keep students, staff, visitors and facilities safe. VMS systems are designed with efficiency tools such as touch-screen technology, map-based interfaces, context-sensitive pop-up controls and time slice forensics. Combined with an event-management platform, VMS systems easily integrate with an array of physical security solutions such as intruder alarms, access control, intrusion detection, video content analytics, licence plate recognition and other operation systems to provide security professionals the information needed to safeguard their campus and make better and more informed decisions.

Because IP video surveillance systems are evolving into a more comprehensive security solution in the school environment, a VMS system must be proactive and results-oriented. To help schools establish VMS best practices that, together with IP surveillance systems, can provide the foundation for a safe and secure environment, the following should be considered.

Collaborative workflow

IP-based security solutions open the door for linking systems and areas, allowing the entire campus to be tied to the VMS platform for improved situational awareness. An open platform conforming to industry standards enables schools to choose best-of-breed components, combined in any configuration for any size application. Ideally, VMS technology should be intuitive and relatively simple to configure as well as readily able to integrate with network-based systems. From an operations standpoint, authorised users should be able to view and control the system from anywhere on the network through a highly intuitive, unified user interface. Optimised by touch-screen operation, the interface would provide instantaneous control of all aspects of video detection, analysis, delivery and response.

Interoperability and connectivity with local municipal authorities running identical VMS systems makes vital information immediately available to those officials for collaborative handling in the event of a fire, lockdown or other serious threats at the school. Programming the management server on a granular level for information access and control helps to ensure the integrity of the system.

Fingertip control with time saving tools and analytics

Whether it’s a primary school with 10 cameras or a multi-complex university with hundreds of security cameras, managing the video and data is better accomplished with easy to use, intelligent tools available on a VMS system. Traditional record/review systems typically have too few operators with too little time, trying to handle too many cameras and too much information. The VMS system tools provide operators with full control over all camera parameters, including PTZ presets, joystick control, digital zoom in/out and more. These intuitive and time-saving features, available on the user interface, give the advantage needed to make the right decision quickly when an alert is sent. For example, if an alarmed door exit at a facility is breached, the VMS system can be pre-programmed to automatically “push” the video to pre-selected devices, enabling authorities in the area to immediately view the incident and then take the necessary action. This capability enables schools to react to events and potential problems quickly and effectively which in turn can prevent them from escalating.

VMS system capabilities can also be used for after-the-fact investigation. Tools such as digital PTZ into recorded images, time slicing and bi-directional playback with variable speed and instant access to recorded events via an events list offer faster access to data about an incident. For example, using digital PTZ to manipulate images gives operators the ability to sharpen the video, get a wider view or analyse multiple camera angles. Using these tools to mine evidence – for example, how a criminal proceeded from floor to floor looking for a target – security personnel can present a more complete case, even potentially showing intent of a criminal activity.

Streaming and mobile applications

Situational awareness is a key foundation of security. A full complement of well-placed high definition (HD) and megapixel video surveillance cameras can provide that awareness. The only problem is, not every school will have dedicated networks for transmission nor will incidents conveniently take place between the hours of 9 and 5 when the control room might be fully staffed and able to monitor events. By incorporating VMS into the mix, this challenge can be addressed.

Tablet and smartphone
Smartphones and iPads are as much a part of security technology solutions as are cameras and video recorders

New VMS technology enables standard definition and HD/megapixel cameras to stream high resolution video over a low-speed connection or limited bandwidth network. Video streams through the cloud can be monitored at full frame rates (with less than one-second lag) including the ability to digitally control pan/tilt/zoom functions. Streams can then be encrypted to enable a secure connection both inside and outside a school network, with all the resulting collaborative and safety advantages.

Today, smartphones, iPads and other portable devices are as much a part of security technology solutions as are cameras and video recorders. Mobile security as an element of VMS ensures operational efficiencies that would be almost impossible for a non-managed (mobile) system to achieve. With the advent of High Definition Interactive Streaming (HDIS) Technology, streaming of multiple SD and HD cameras simultaneously to mobile devices all at full frame rate (30 FPS) and over limited bandwidths is enabled. More specifically, HDIS technology enables full motion playback of up to 16 HD video streams of live or recorded video at their original frame rate with full digital PTZ control of each camera over limited bandwidth network connections via 3G and 4G Wi-Fi, broadband and Internet. This technology allows remote users to access multiple HD images in real-time from an iPad tablet, (and soon an iPhone) PC or laptop with a standard web interface.

Benefits to schools beyond security

In addition to keeping students and staff safe, surveillance cameras can help administrators manage discipline problems or monitor facility levels and capabilities. Video can help to manage the flow of students, analyse bottlenecks that form between classes or view vehicle traffic flow. Video can also track facility occupancy, especially during the weekend or off-hours. Video capability is an excellent resource for facility management by enabling operators to view and evaluate a physical plant system malfunction before deciding whether to send a technician. Integrated with the HVAC system, surveillance video could help save energy costs by automatically turning up the air conditioner only when a room is occupied. And when mobile security is implemented, individuals in the field can use their smart phones to send video images of a dangerous situation such as a sewer without a grate to authorities.

In today’s education environment, developing VMS best practices not only optimises state of the art imaging technology; they also enable the central management of complex systems and allow users to have an entire facility at their fingertips.

The physical side of data protection
The physical side of data protection

The impact of the COVID-19 pandemic has accentuated our digital dependency, on a global scale. Data centres have become even more critical to modern society. The processing and storage of information underpin the economy, characterised by a consistent increase in the volume of data and applications, and reliance upon the internet and IT services. Data centres classed as CNI As such, they are now classed as Critical National Infrastructure (CNI) and sit under the protection of the National Cyber Security Centre (NCSC), and the Centre for the Protection of National Infrastructure (CPNI). As land continues to surge in value, data centre operators are often limited for choice, on where they place their sites and are increasingly forced to consider developed areas, close to other infrastructures, such as housing or industrial sites. Complex security needs One misconception when it comes to data centres is that physical security is straightforward One misconception when it comes to data centres is that physical security is straightforward. However, in practice, things are far more complex. On top of protecting the external perimeter, thought must also be given to factors, such as access control, hostile vehicle mitigation (HVM), protecting power infrastructure, as well as standby generators and localising security devices to operate independently of the main data centre. Face value How a site looks is more important than you may think. Specify security that appears too hostile risks blatantly advertising that you’re protecting a valuable target, ironically making it more interesting to opportunistic intruders. The heightened security that we recommend to clients for these types of sites, include 4 m high-security fences, coils of razor wire, CCTV, and floodlighting. When used together in an integrated approach, it’s easy to see how they make the site appear hostile against its surroundings. However, it must appear secure enough to give the client peace of mind that the site is adequately protected. Getting the balance right is crucial. So, how do you balance security, acoustics and aesthetics harmoniously? Security comes first These are essential facilities and as a result, they require appropriate security investment. Cutting corners leads to a greater long-term expense and increases the likelihood of highly disruptive attacks. Checkpoints Fortunately, guidance is available through independent accreditations and certifications, such as the Loss Prevention Certification Board’s (LPCB) LPS 1175 ratings, the PAS 68 HVM rating, CPNI approval, and the police initiative - Secured by Design (SBD). Thorough technical evaluation and quality audit These bodies employ thorough technical evaluation work and rigorous quality audit processes to ensure products deliver proven levels of protection. With untested security measures, you will not know whether a product works until an attack occurs. Specifying products accredited by established bodies removes this concern. High maintenance Simply installing security measures and hoping for the best will not guarantee 24/7 protection. Just as you would keep computer software and hardware updated, to provide the best level of protection for the data, physical security also needs to be well-maintained, in order to ensure it is providing optimum performance. Importance of testing physical security parameters Inspecting the fence line may seem obvious and straightforward, but it needs to be done regularly. From our experience, this is something that is frequently overlooked. The research we conducted revealed that 63% of companies never test their physical security. They should check the perimeter on both sides and look for any attempted breaches. Foliage, weather conditions or topography changes can also affect security integrity. Companies should also check all fixtures and fittings, looking for damage and corrosion, and clear any litter and debris away. Accessibility When considering access control, speed gates offer an excellent solution for data centres. How quickly a gate can open and close is essential, especially when access to the site is restricted. The consequences of access control equipment failing can be extremely serious, far over a minor irritation or inconvenience. Vehicle and pedestrian barriers, especially if automated, require special attention to maintain effective security and efficiency. Volume control Data centres don’t generally make the best neighbours. The noise created from their 24-hour operation can be considerable. HVAC systems, event-triggered security and fire alarms, HV substations, and vehicle traffic can quickly become unbearable for residents. Secure and soundproof perimeter As well as having excellent noise-reducing properties, timber is also a robust material for security fencing So, how do you create a secure and soundproof perimeter? Fortunately, through LPS 1175 certification and CPNI approval, it is possible to combine high-security performance and up to 28dB of noise reduction capabilities. As well as having excellent noise-reducing properties, timber is also a robust material for security fencing. Seamlessly locking thick timber boards create a flat face, making climbing difficult and the solid boards prevent lines of sight into the facility. For extra protection, steel mesh can either be added to one side of the fence or sandwiched between the timber boards, making it extremely difficult to break through. A fair façade A high-security timber fence can be both, aesthetically pleasing and disguise its security credentials. Its pleasant natural façade provides a foil to the stern steel bars and mesh, often seen with other high-security solutions. Of course, it’s still important that fencing serves its primary purposes, so make sure you refer to certifications, to establish a product’s security and acoustic performance. Better protected The value of data cannot be overstated. A breach can have severe consequences for public safety and the economy, leading to serious national security implications. Countering varied security threats Data centres are faced with an incredibly diverse range of threats, including activism, sabotage, trespass, and terrorism on a daily basis. It’s no wonder the government has taken an active role in assisting with their protection through the medium of the CPNI and NCSC. By working with government bodies such as the CPNI and certification boards like the LPCB, specifiers can access a vault of useful knowledge and advice. This will guide them to effective and quality products that are appropriate for their specific site in question, ensuring it’s kept safe and secure.

Data explosion: Futureproofing your video surveillance infrastructure
Data explosion: Futureproofing your video surveillance infrastructure

Video surveillance systems are producing more unstructured data than ever before. A dramatic decrease in camera costs in recent years has led many businesses to invest in comprehensive surveillance coverage, with more cameras generating more data. Plus, advances in technology mean that the newest (8K) cameras are generating approximately 800% more data than their predecessors (standard definition). Traditional entry-level solutions like network video recorders (NVRs) simply aren’t built to handle massive amounts of data in an efficient, resilient and cost-effective manner. This has left many security pioneers grappling with a data storage conundrum. Should they continue adding more NVR boxes? Or is there another, better, route? Retaining video data In short, yes. To future proof their video surveillance infrastructure, an increasing number of businesses are adopting an end-to-end surveillance architecture with well-integrated, purpose-built platforms for handling video data through its lifecycle. This presents significant advantages in terms of security, compliance and scalability, as well as unlocking new possibilities for data enrichment. All of this with a lower total cost of ownership than traditional solutions. Security teams would typically delete recorded surveillance footage after a few days or weeks Previously, security teams would typically delete recorded surveillance footage after a few days or weeks. However, thanks to increasingly stringent legal and compliance demands, many are now required to retain video data for months or even years. There’s no doubt that this can potentially benefit investigations and increase prosecutions, but it also puts significant pressure on businesses’ storage infrastructure. Data lifecycle management This necessitates a more intelligent approach to data lifecycle management. Rather than simply storing video data in a single location until it’s wiped, an end-to-end video surveillance solution can intelligently migrate data to different storage platforms and media as it ages. So, how does this work? Video is recorded and analysed on a combination of NVR, hyperconverged infrastructure (HCI) and application servers. Then, it’s moved to resilient file storage for a pre-determined period, where it can be immediately retrieved and accessed for review. Finally, based on policies set by heads of security, data is moved from file storage to highly secure, low-cost archive storage such as an object, tape or cloud. Data is moved from file storage to highly secure, low-cost archive storage Long-term storage This process is known as tiering. It allows businesses to use reliable, inexpensive long-term storage for most of their data, whilst still enabling security pioneers to retrieve video data when the need arises, such as during a compliance audit, or to review footage following a security breach. In a nutshell, it offers them the best of both worlds. Scaling your video surveillance infrastructure can be a headache. Businesses that rely on NVRs – even high-end units with 64 or even 96 hard drives – are finding themselves running out of capacity increasingly quickly. In order to scale, security pioneers then have to procure new boxes. With NVRs, this inevitably involves a degree of guesswork. Should they go for the largest possible option, and risk over provisioning? Or perhaps a smaller option, and risk running out of capacity again? Common management console Security pioneers can easily add or remove storage capacity or compute resources – separately or together As businesses add new cameras or replace existing ones, many end up with inadequate surveillance infrastructure made up of multiple NVR boxes along with several application servers for running other surveillance functions such as access control, security photo databases, analytics, etc. This patchwork approach leaves security pioneers scrambling for capacity, maintaining various hardware footprints, repeating updates and checks across multiple systems, and taking up valuable time that could be better spent elsewhere. By contrast, flexible HCI surveillance platforms aggregate the storage and ecosystem applications to run on the same infrastructure and combine viewing under a common management console, avoiding ‘swivel chair’ management workflows. Plus, they offer seamless scalability. Security pioneers can easily add or remove storage capacity or compute resources – separately or together. Data storage solutions Over time, this ensures a lower total cost of ownership. First and foremost, it removes the risk of over provisioning and helps to control hardware sprawl. This in turn leads to hardware maintenance savings and lower power use. Many security pioneers are now looking beyond simple data storage solutions for their video surveillance footage. Meta tags can provide context around data, making it easier to find and access when needed Instead, they’re asking themselves how analysing this data can enable their teams to work faster, more efficiently and productively. Implementing an end-to-end video surveillance architecture enables users to take advantage of AI and machine learning applications which can tag and enrich video surveillance data. These have several key benefits. Firstly, meta tags can provide context around data, making it easier to find and access when needed. Object storage platform For instance, if security teams are notified of a suspicious red truck, they can quickly find data with this tag, rather than manually searching through hours of data, which can feel like looking for a needle in a haystack. Plus, meta tags can be used to mark data for future analysis. This means that as algorithms are run over time, policies can be set to automatically store data in the right location. For example, if a video is determined to contain cars driving in and out of your premises, it would be moved to long-term archiving such as an object storage platform for compliance purposes. If, on the other hand, it contained 24 hours of an empty parking lot, it could be wiped. These same meta tags may be used to eventually expire the compliance data in the archive after it is no longer needed based on policy. Video surveillance architecture Continuing to rely on traditional systems like NVRs will fast become unsustainable for businesses Even if your organisation isn’t using machine learning or artificial intelligence-powered applications to enhance your data today, it probably will be one, three, or even five years down the line. Implementing a flexible end-to-end video surveillance solution prepares you for this possibility. With new advances in technology, the quantity of data captured by video surveillance systems will continue rising throughout the coming decade. As such, continuing to rely on traditional systems like NVRs will fast become unsustainable for businesses. Looking forward, when moving to an end-to-end video surveillance architecture, security pioneers should make sure to evaluate options from different vendors. For true futureproofing, it’s a good idea to opt for a flexible, modular solution, which allow different elements to be upgraded to more advanced technologies when they become available.

How can the security industry provide affordable and cost-effective solutions?
How can the security industry provide affordable and cost-effective solutions?

Cost is a reality to be managed. No matter how powerful or desirable a technology may be to a customer, the sale often comes down to the basic question: Can I afford it? And affordability extends not just to the purchase price, but to the cost of technology over its lifespan. In addition to advances in technology capabilities, the security industry has also achieved inroads to make its offerings more worth the cost. We asked this week’s Expert Panel Roundtable: What is the physical security industry doing to make more affordable and cost-effective technology solutions for end users?
