Electronic lock system products updated recently
In part one of this feature, we introduced the shotbolt – a solenoid actuator – as the workhorse at the heart of most straightforward electric locking systems. Shotbolts remain at the core of most sophisticated electric locking solutions as well. But they are supplemented by materials and technologies that provide characteristics suited to specialist security applications. Here we look at some more demanding electric locking applications and contemporary solutions. Preventing forced entry Where the end of the shotbolt is accessible, the electric holding force can be overcome by physical force. That’s why anti-jacking technology is now a frequent feature of contemporary electric solenoid lock actuators. Anti-jacking, dead-locking or ‘bloc’ technology (the latter patented by MSL) is inherent to the way the locking assembly is designed to suit the requirements of the end application. The patented bloc anti-jacking system is highly effective and incorporated into many MSL shotbolts deployed in electric locking applications. The bloc technology uses a ring of steel balls in a shaped internal housing to physically jam the actuated bolt in place. A range of marine locks is widely used on Superyachts for rapid lockdown security from the helm Real life applications for MSL anti-jacking and bloc-equipped shotbolts include installation in the back of supermarket trucks to secure the roller shutter. Once locked from the cab, or remotely using radio technology, these shutters cannot be forced open by anyone with ‘undesirable intentions’ armed with a jemmy. A range of marine locks is widely used on Superyachts for rapid lockdown security from the helm. While anti-jacking features are an option on these shotbolts, consideration was given to the construction materials to provide durability in saltwater environments. Marine locks use corrosion-proof stainless steel, which is also highly polished to be aesthetically pleasing to suit the prestigious nature of the vessel while hiding the innovative technology that prevents the lock being forced open by intruders who may board the craft. Rotary and proportional solenoids sound unlikely but are now common A less obvious example of integrated technology to prevent forced override is a floor lock. This lock assembly is mounted beneath the floor with round-top stainless-steel bolts that project upwards when actuated. They are designed to lock all-glass doors and are arguably the only discreet and attractive way to lock glass doors securely. In a prestigious installation at a historic entranceway in Edinburgh University, the floor locks are remotely controlled from an emergency button behind the reception desk. They act on twin sets of glass doors to quickly allow the doors to close and then lock them closed with another set of subfloor locks. No amount of stamping on or hitting the 15mm protruding bolt pin will cause it to yield, thus preventing intruders from entering. Or leaving! Explosion proofing In many environments, electric locking technology must be ATEX certified to mitigate any risk of explosion. For example, remote electric locking is used widely on oil and gas rigs for stringent access control, general security and for emergency shutter release in the event of fire. It’s also used across many industrial sectors where explosion risks exist, including flour milling, In many environments, electric locking technology must be ATEX certified to mitigate any risk of explosionpowder producers, paint manufacture, etc. This adds a new dimension to the actuator design, demanding not only intrinsically safe electrical circuits and solenoid coils, but the careful selection of metals and materials to eliminate the chance of sparks arising from moving parts. Resilience under pressure The technology boundaries of solenoids are always being pushed. Rotary and proportional solenoids sound unlikely but are now common. More recently, while not directly related to security in the traditional sense, proportional solenoid valves for accurately controlling the flow of hydrogen and gases now exist. Magnet Schultz has an extensive and somewhat innovative new range of hydrogen valves proving popular in the energy and automotive sectors (Fig. 2-6). There’s a different kind of security risk at play here when dealing with hydrogen under pressures of up to 1050 bar. Bio security Less an issue for the complexity of locking technology but more an imperative for the effectiveness of an electric lock is the frequent use of shotbolts in the bio research sector. Remote electric locking is commonplace in many bioreactor applications. Cultures being grown inside bioreactors can be undesirable agents, making 100% dependable locking of bioreactor lids essential to prevent untimely access or the unwanted escape of organisms. Again, that has proven to be topical in the current climate of recurring coronavirus outbreaks around the world. More than meets the eye In part one, I started by headlining that there’s more to electric lock actuation in all manner of security applications than meets the eye and pointed out that while electric locking is among the most ubiquitous examples of everyday security, the complexity often involved and the advanced technologies deployed typically go unnoticed.Integrating the simplest linear actuator into a complex system is rarely simple For end users, that’s a very good thing. But for electro-mechanical engineers designing a system, it can present a challenge. Our goal at Magnet Schultz is to provide a clearer insight into today’s electric locking industry sector and the wide range of locking solutions available – from the straightforward to the specialized and sophisticated. Integrating the simplest linear actuator into a complex system is rarely simple. There’s no substitute for expertise and experience, and that’s what MSL offers as an outsource service to designers. One benefit afforded to those of us in the actuator industry with a very narrow but intense focus is not just understanding the advantages and limitations of solenoid technology, but the visibility of, and participation in, emerging developments in the science of electric locking. Knowing what’s achievable is invaluable in every project development phase.
A defibrillator can save the life of a person suffering from cardiac arrest – but it is most effective when used in the first few minutes of the patient collapsing. Studies have shown that a shock given within the first three minutes provides the best chance of survival and even one minute of further delay can substantially lower the chances of recovering. Public Access Defibrillators (PADs) were created to allow untrained members of the public to deliver life-saving treatment in those precious minutes before an ambulance arrives. There are currently over 10,000 in the UK, located in parks, offices, high streets and sporting venues, and they are especially popular in rural communities, where ambulance response times are longer. Every second counts Over the years there has been a long-running debate as to whether PADs should be kept openly accessible or locked. Leaving them open could lead to theft, vandalism or misuse. Leaving them locked could mean that precious moments are lost waiting for a local guardian to arrive – and could even cost a life. To save as many lives as possible, it’s clear that PADs need to be available 24/7, fully operational and easily accessible to users and local guardians. But there is a solution that can meet all these conditions – a lock that can protect against vandalism while providing convenient instant access when required. Life-saving solutions Over the years there has been a long-running debate as to whether PADs should be kept openly accessible or lockedDigital locks are ideal for securing PADs because they don’t require a key, and anyone can be given access over the phone. In the case of a cardiac arrest, the user calls 999 and the ambulance controller provides them with a simple, easy-to-remember code. The ambulance controller can then advise them, step by step, what to do. Local guardians, who have responsibility for the PAD, can be provided with an override key to enable them to monitor and maintain the defibrillator. The PAD cabinets built by Duchy Defibrillators show exactly how this works in practice. Based in rural Cornwall, Duchy Defibrillators manufactures, supplies and installs monitored PAD cabinets. To provide public access to the defibrillators, it needed a lock that could keep its cabinets secure, make them easily accessible and withstand the stormy Cornish weather. Codelocks recommended a digital electronic lock that could operate on a standalone battery, making it especially suitable for remote areas. As well as offering flexible access, digital locks come with a range of varying options and functions to suit different applications. As Duchy Defibrillator cabinets are installed in a wide variety of locations and sometimes need to withstand outdoor exposure, it opted for a robust electronic digital lock that is both affordable and easy to set up. A digital-access revolution Using smart locks in combination with a dedicated app or portal allows operators to send time-sensitive codes to end-users The example of Duchy Defibrillators shows how digital locks can be used to keep defibrillator cabinets secure while affording instant access to users when they are needed. But the flexibility of digital locks also makes them suitable for securing property and equipment in a wide variety of situations, especially for shared and public facilities. This is why you’ll increasingly see digital locks used to secure restricted areas in hospitals, schools and offices, as well as shared facilities like hotel and gym lockers, public restrooms and more. Digital locks are available for a number of specific applications, including doors, lockers and cabinets. They can range from simple mechanical locks through to more sophisticated electronic locks and state-of-the-art smart locks. Using smart locks in combination with a dedicated app or portal allows operators to send time-sensitive codes to end users – making them very popular for contactless entry and with facilities managers that need to manage access to buildings and campuses. One thing is certain – whatever your access control requirements are, there’s a keyless lock solution to suit. The digital access revolution is here.
The experience of the COVID-19 pandemic has made us all more conscious of who is coming and going from our property. Whether it is a family home, business premises or public building, property owners want full control over access for protection and peace of mind. As a provider of access control technologies, we are seeing a growing demand for automated gates with a variety of access control systems. There are a number of considerations that buyers need to make when investing. And as an installer, there is advice that you can offer to help your clients make the right choice for their property. Here are some of the key considerations you’ll need to make and discuss with your client. Whomever you buy from, you should be offered more than a simple instruction manual. Electronic locks, magnetic locks and code security In the first instance, you’ll need to advise on the type of lock and access control available. Electronic locks release on the operation of the automation system to allow the gates to open. Locks are required for all non-locking (also known as reversible) operators and are recommended for any gate on a multi-user site or any gate over 2.5m. Apply the same logic to an automated gate as you would to a domestic door – for example, you wouldn’t fit your front door with a lock on the same side as the hinges or a drop bolt at the hinge end of a manual gate so why dispense with this logic when the gate is automated? Electronic locks release on the operation of the automation system to allow the gates to open There are a number of locks on the market including magnetic locks, drop locks that “shoot” a bolt into the ground and side latching locks. These are all designed for external use. While the gate itself will provide physical security, the customer will want to feel in control of who enters their property, when and for what purpose. Consider access for mail and deliveries, waste disposal and visitors arriving on foot etc. There is a range of options available. Intercom systems will allow the user to vet visitors, keypad entry can allow remote access for visitors with a specific code, remote controls allow an oncoming driver to open the gates without getting out of the vehicle, and a timer control can be used to open or close the gates at certain times of the day. Vehicle detection loops can be installed discreetly under the tarmac allowing the presence of vehicles to exit the gates and prevent closing while obstructed. Sliding gates versus swinging gates There are a number of locks on the market including magnetic locks, drop locks that “shoot” a bolt into the ground and side latching locks Gates can be automated to either swing or to slide open and in the case of swinging gates, the opener may be concealed underground or gate mounted. The most suitable opener for your installation will depend on the space available and the type of gate selected. Concealed underground automation is ideal for highly ornate gates. However, where gates are fully infilled (typical of many timber designs), gate mounted openers are concealed from the front of the gate by the gate leaf and present a cost-effective option. The choice between slide and swing is largely down to space - swing gates require a clear space for their opening arc while sliding gates require space to one or both sides of the gate. Sliding gates are perhaps the best choice where the drive slopes or when drive space is limited, as they use the least space when opening. Voltage Most swing gate and sliding systems are available in 24v or 230v. The 24v systems still need 230v mains power – there is a transformer built into the 24v control panels. Deciding which voltage to use can include a combination of factors such as the material of the gates, the location of the system and the safety features you want. Concealed underground automation is ideal for highly ornate gates With wrought iron gates, the wind can pass through them whereas with fully boarded wooden gates (popular because they give full privacy) the wind has nowhere to go, so they act like sails. For commercial or industrial applications with larger entrances and a heavy gate, you may need 3 Phase 400v power (sliding gates only). Installing gate motors in confined spaces The environment in which you are fitting may well influence which gate and motor you recommend. Will it be in an exposed area which is subject to the elements? Will it be positioned on a slope? Sliding gates are perhaps the best choice where the drive slopes or when drive space is limited Installers have always faced the challenge of installing gate motors in confined spaces. When fitting a pedestrian gate, there is often limited space in which to work – potentially making an installation time consuming and technically demanding. If this is the case for you, consider a gate operator which is designed specifically for installations with limited space for maneuver. An example of this is the E5 compact gate operator. The operator is not only small but has an optional slide lever attachment designed for installations where there is extremely limited space, meaning that just 8cm of the pillar is needed for installation. What’s more, improved fixing points and a simple ‘hook and fasten’ process means assembly is safe, quick and straight forward. Ultimately, you’ll be looking for a good quality, reliable product with good service. Work with a supplier that offers more than just a manual. If they are happy to offer training, their time and advice when you buy, the chances are you’ll get their support long term.

As the media often reports, the world of cybersecurity can be seen like the ‘Wild West’. There’s now a wide range of Internet of Things (IoT) devices connected to the web, making this a hot topic. Among these devices are security cameras. IoT devices are computers that use software that makes them vulnerable. As the famous cybersecurity evangelist Mikko Hypponen says, "If a device is smart, it's vulnerable!" Hypponen is right. On a daily basis, new vulnerabilities are found in software, regardless of the manufacturer. In 2019, more than 12,000 vulnerabilities worldwide were made public and reported as a CVE (Common Vulnerability and Exposure) in the National Vulnerability Database (NVD). Unfortunately, vulnerabilities are a given. What really matters is how a company deals with and resolves vulnerabilities. Cybersecurity vulnerabilities Awareness of cybersecurity vulnerabilities is vitally important to protect one, one’s business and the Internet Awareness of cybersecurity vulnerabilities is vitally important to protect one, one’s business and the Internet, but it’s also important to understand that a vulnerability is not synonymous with “backdoor”, and is not necessarily indicative of “cheap quality.” But there are companies out there that are embedding safeguards into their development processes to reduce the risks. One could see them as ‘Sheriffs’, taking steps to make this Wild West a little safer. Hikvision ‘Secure-by-Design’ Manufacturers of IoT devices can significantly reduce these vulnerabilities during the production of devices Security cameras, like all other IoT devices, are vulnerable to cyberattacks. Fortunately, manufacturers of IoT devices can significantly reduce these vulnerabilities during the production of devices, using a process called ‘Secure-by-Design’. Implementation of Secure-by-Design requires a commitment on the part of the manufacturer’s management team and a serious investment in resources and technology, which can result in a longer production process and a higher cost of the IoT device. Cost is often the reason why some IoT device manufacturers do not use Secure-by-Design (and are indeed cheaper). Hikvision is a producer of IoT devices that takes security and privacy very seriously and has implemented Secure-by-Design in its production process. Management supports this process and has even set up a dedicated internal cybersecurity structure charged with product cybersecurity. This group is also the central point of contact for all other cybersecurity matters. Product testing Hikvision Security Development Life Cycle (HSDLC) is an essential part of Hikvision's cybersecurity program The Hikvision Security Development Life Cycle (HSDLC) is an essential part of Hikvision's cybersecurity program. Cybersecurity checks take place at every stage of product development — from concept to delivery. For example, product testing takes place during the verification phase, the company also regularly invites well-known security companies and public testing platforms to conduct penetrating testing. There is no guarantee if Hikvision products are immune to hacking, but the HSDLC is a testament to a manufacturer that makes every effort to produce products that are as cyber secure as possible. In addition to the Secure-by-Design process, Hikvision opened a Source Code Transparency Center (SCTC) lab in California in 2018, being a lab to open such a center. At this center, U.S., the Canadian government and law enforcement agencies can view and evaluate the source code of Hikvision IoT devices (IP cameras and network video recorders). Hikvision firmware Hikvision has a Vulnerability Management Program in place when a vulnerability is discovered It’s important to emphasize that no product is 100 percent secure. Hikvision has a Vulnerability Management Program in place when a vulnerability is discovered in a product. To date, vulnerabilities that have been reported to Hikvision and/or made publicly known, have been patched in the latest Hikvision firmware, and are readily available on the Hikvision website. In addition, Hikvision is a CVE CNA, and has committed to continuing to work with third-party white-hat hackers and security researchers, to find, patch and publicly release updates to products in a timely manner. These vulnerabilities are collected in the National Vulnerability Database (NVD) and are public. Hikvision recommends that customers who are interested in purchasing security cameras inquire about a manufacturer’s cybersecurity practices and if they have an established Vulnerability Management Program. Cybersecurity questions to consider The cybersecurity of IoT devices is a topic that needs to be addressed in a serious way and it should play an essential role in the product development process, beginning at the concept phase of an IoT product. This requires time, investment and knowledge. Consider the following questions: Trust on the manufacturer of a low-cost security camera Manufacturer with a dedicated cybersecurity organization Manufacturer on handling the vulnerabilities These are the questions that everyone should ask themselves when making a purchase, be it a camera or any other IoT product. Cybersecurity practices There is no absolute 100% guarantee of security, but Hikvision has practices to ensure the cybersecurity for its cameras. Cooperation, with its customers, installers, distributors and partners, and full transparency are key elements to successfully secure IoT devices. When one reads cybersecurity news, one is invited to look beyond the headlines, and really get to know the companies that produce the IoT devices. Before one buys a security camera or any IoT device, it is advisable to check out the manufacturer’s cybersecurity practices, look for a company with a robust vulnerability management program, a company that aligns itself with Secure-by-Design and Privacy-by-Design and a company that employs cybersecurity professionals who are ready and eager to answer one’s questions. One may remember that there are Sheriffs out there, as well as bandits.
Businesses are now gradually reopening in many countries, and people can return to restaurants, office buildings, and public spaces. A safe reopening process will rely heavily on effective public health strategies, including increased testing for the virus, social distancing, occupancy restrictions, and cleaning and disinfection activities. In many countries, temperature measurement and the wearing of masks have been commonly made mandatory in both business and public environments. While social distancing and occupancy restrictions are considered necessary in public areas such as shopping malls and transportation hubs, workplaces like office buildings and industrial parks are looking for solutions featuring authorized entries with confidence. In lifting the restrictions for businesses and public areas, innovative video technologies can also help organizations meet and exceed health guidelines for safe and effective reopening. Temperature screening at entry The Centers for Disease Control and Prevention (CDC) in the United States, a very well-known public health organization, have issued new guidelines for reopening offices. The CDC advises daily health checks including temperature screenings before employees enter a workplace. To achieve this, security cameras equipped with thermographic video technology can be an effective tool for rapid and safe initial temperature screening. Applications include, for example, schools, industrial parks, hospitals, office buildings, malls and hotels, etc. Hikvision’s temperature screening solutions offer various product types including installed thermographic cameras, handheld thermographic cameras, metal detector doors, and MinMoe access terminals that can be flexibly deployed for a wide range of applications. Video monitoring for mask compliance Wearing masks is recommended as a measure to contain respiratory droplets and protect the general public. Masks are also commonly included in worldwide health guidelines towards reopening. Store managers also need to identify and mitigate areas where shoppers may congregate Hence, compliance with this guideline has become crucial to many organizations. Video technology can help monitor the use of protective masks in clever and unobtrusive ways. AI algorithms can detect whether a person is wearing a mask. The system then triggers a pre-defined action if no mask is detected, such as, for example, a voice prompt or a link to an access system to deny entry. This provides a simple way to monitor the situation, or even to remind people of the rules. Hikvision’s thermal and AcuSense cameras, as well as MinMoe temperature screening terminals are equipped to detect masks. A specialized interface on Hikvision’s DeepinMind NVRs can also be used to visually display temperature and mask status together, making monitoring much easier. Crowd density control Social distancing plays an important role in “flattening the curve” in the spread of the coronavirus. These technologies use people counting and 3D modeling to measure the distance between people accurately In various countries, the recommended physical distancing might differ slightly, but maintaining a distance of a meter or more (3-6 feet) will remain a key recommendation of health authorities. In addition, store managers also need to identify and mitigate areas where shoppers may congregate, so as to ensure safe shopping spaces. Technologies incorporating social distancing and occupancy detection can be put into places like these to assist the process. Hikvision Flow Control Hikvision’s Flow Control system utilizes highly accurate people counting technology. A clear, dynamic display and real-time alerts ensure pre-defined capacity thresholds are never exceeded, even in locations with multiple entrances and exits, such as, for example, shopping malls and supermarkets. Video solution provides the necessary features and functionalities to assist with the process of social distancing A digital sign can be integrated at entrance areas to display real-time occupancy data, as well as temperature and mask information, letting customers know when it is safe to enter premises. In waiting areas such as cash registers in supermarkets and indoor ATMs in malls, Hikvision’s video solution provides the necessary features and functionalities to assist with the process of social distancing. These technologies use people counting and 3D modeling to measure the distance between people accurately. The exact measurement can be adjusted, well within the social distancing minimum separation guidelines. Touch-free access control Schools and workplaces have previously made use of traditional access control and time attendance systems such as ID card swiping, PIN codes, or fingerprint scans, which require staff and students to frequently touch shared surfaces. This only increases the risk of spreading infection. With touch-free access control terminals, organizations can not only eliminate the risk, but greatly enhance their daily operational efficiency. Hikvision’s MinMoe temperature screening terminals unify temperature screening, mask detection, and access control & time attendance in one model. The system only grants entries when the guidelines are met, which is particularly useful in highly-populated workplaces like industrial parks and office buildings.
