The term ‘marine’ comes from the Latin mare, meaning sea or ocean, and marine habitats can be divided into two categories: coastal and open ocean. Video surveillance (VS) applications can cover both types of marine environment with system for ships, maritime ports, onshore and offshore installations, etc. We should want to further analyse VS for ships and try to explain the types of ships on which it can be used, the ways in which VS can be used on ships, the typical certifications in use and what features a camera station must have to be installed on a ship. Starting with ships that have a minimum tonnage, around the world we have: liquefied natural gas (LNG) tankers, passengers ships, chemical tankers, crude oil tankers, container ships, general cargo ships and bulk carriers.As the LNG market grows rapidly, the fleet of LNG carriers continues to experience tremendous growth, offering more opportunities for VS Video surveillance for all marine vessels An LNG carrier is a tank ship designed for transporting liquefied natural gas. As the LNG market grows rapidly, the fleet of LNG carriers continues to experience tremendous growth. A passenger ship is a merchant ship whose primary function is to carry passengers by sea. This category does not include cargo vessels which have accommodation for a limited number of passengers, but rather includes the likes of ferries, yachts, ocean liners and cruise ships. A chemical tanker is a type of tank ship designed to transport chemicals in bulk. These ships can also carry other types of sensitive cargo which require a high standard of tank cleaning, such as palm oil, vegetable oils, tallow, caustic soda and methanol. An oil tanker, also known as a petroleum tanker, is a merchant ship designed for the bulk transport of oil. There are two basic types of oil tankers: crude tankers and product tankers. Crude tankers move large quantities of unrefined crude oil from its point of extraction to refineries. Product tankers, generally much smaller, are designed to move refined products from refineries to points near consuming markets. Container ships are cargo ships that carry their entire load in truck-size intermodal containers: a technique called containerisation. They are a common means of commercial intermodal freight transport and now carry most seagoing non-bulk cargo. Today, about 90% of non-bulk cargo worldwide is transported by container. A cargo ship or freighter ship is any sort of ship or vessel that carries cargo, goods and materials from one port to another. Cargo ships are specially designed for the task, often being equipped with cranes and other mechanisms to load and unload, and come in all sizes. Bulk carriers make up 15%–17% of the world's merchant ships and they are specially designed to transport unpackaged bulk cargo such as grains, coal, ore and cement in its cargo holds. For all these ships the protection of vessels, cargo and crew is a priority, that’s why the adoption of VS technology plays a key part in terms of security and safety. Human error is regularly named as a major factor in ship accidents, and one way to avoid it is to aid seafarers by providing them with technology and equipment that is reliable and easy to use in all weather and sea conditions. Marine VS encompasses liquefied natural gas (LNG) tankers, passengers ships, chemical tankers, crude oil tankers, container ships, general cargo ships and bulk carriers Emergency security solutions on ship One of the most important applications for camera stations is during “docking”. Mooring is the securing or confining of a vessel in a particular location with a fixed or a floating object (jetty, pier, ship, barge, buoy, etc.) as various cargo operations are carried out. Docking is the final stage of mooring operations when the ship docks to the jetty. This is a very delicate operation and cameras are very helpful in making sure docking is done without accidents.'Man overboard’ is an emergency in which a person has fallen off a boat or ship into the water, and can happen at any time during the day or night Another important application for camera stations is the Man Overboard detection system (MOB). ‘Man overboard’ is an emergency in which a person has fallen off a boat or ship into the water. Man overboard events can happen at any time during the day or night, in all types of weather and sea conditions, and from almost any location on the ship, ranging from a few tens of feet above the water, to over 180 feet. When these events occur, the immediate availability of important data is crucial. Accurate confirmation of the event including time of occurrence, location on the ship and location in the sea is critical. A proactive detection system must immediately and accurately detect man overboard events and provide prompt, actionable data to response personnel. A typical man overboard detection system can report a MOB event in under 1 second. VS on a vessel can also monitor the engine room at all times and provide a good view of people working on dock, machinery and stowed equipment. But what are the most important features that a camera station must have to work in one of the most aggressive environments in nature? Marine surveillance must operate in one of the most harsh environments in nature Ruggedised reliability in surveillance First of all, and perhaps it’s obvious, but it’s extremely important to have camera stations with amazing reliability. Housing units manufactured from AISI 316L stainless steel, passivated and electropolished, makes the cameras completely impervious to air, water, rusting and corrosion, therefore offering excellent weather protection and increased reliability. Housing units manufactured from AISI 316L stainless steel, passivated and electropolished, makes the cameras completely impervious to air, water, rusting and corrosion Sometimes ships also use cameras constructed entirely from technopolymer, which guarantees high impact resistance and superior protection from external weather agents. Keeping the camera glass clean at all times is another essential feature, and it can be done via a wiper/wash system that greatly reduces the need for maintenance. In the case of PTZ cameras, the best option would be a great pan and tilt speed (up to 100°/s). What is the operative temperature range for the cameras? Sea is everywhere and therefore ships go everywhere, from the Arctic Ocean to the Mediterranean, so we need cameras that have to be fully operational across a wide temperature range. -40°C to +65°C covers almost all areas. Analogue or IP Cameras? Actually, both options can be used, especially for applications like docking where it’s important to avoid image delay (as can happen with IP cameras due to the natural latency of data communication over a network). Marine certifications Last but not least, the certifications: Certifications guarantee the quality and reliability of camera stations. There is no compromise! One important certification is the Lloyd’s Register Type Approval which subjects cameras to rigorous testing for performance, vibration (critical on ships), humidity, etc. The application field of the LR Type Approval is VS in public places (e.g. passenger ships), open decks, enclosed spaces that are subjected to heat generated from other equipment, and technical premises. Often, VS cameras used in specific areas of ships, such as hazardous areas, are required to have ATEX and IECEX certifications.
Standards for camera manufacturers presented a new challenge with the introduction of security cameras that require more than 30 Watts of power Standards for camera manufacturers presented a new challenge with the introduction of security cameras that require more than 30 Watts of power. Many of these involve pan-tilt-zoom (PTZ) domes and heaters and blowers that require additional power. This development created two areas of confusion which is highlighted in this article by Neil Heller - Vice President, Vigitron. The first is the ability to define what a 60-watt camera is and what power sources are actually required. The second and more serious is how to provide that power. Both share a commonality in that they lack any form of standardisation. PoE to power 60-watt security camera alone? Let’s start with the definition of the 60-watt camera. As the term suggests, it requires 60 watts or greater, but that doesn’t necessarily mean all the required power comes from a single PoE source. In many cases, camera manufacturers require that PoE only power the camera itself. Looking at these cameras’ power specifications will indicate a required PoE power of 802.3at or 30 watts, thus leaving power to the heaters and blowers requiring a local AC power source. This situation brings into question the value of PoE power if it is restricted to only providing camera power. Another group of PTZ cameras does use PoE for both camera and heater/blower functions, but only when the heater operates within a restricted temperature range. This usually means if your camera is installed in areas where the temperature that can fall below -20 degrees C (approximately -20 degrees F) you will still need a local power AC power source. The third type of security camera relies only on PoE power for both PTZ and heater blower operations. This is confusing, and is often the source of users finding their PTZ has failed at the most inopportune time. Any attempt to transmit 60 watt power over coax cable that is only a single pair should be considered with a great deal of caution, requesting from the transmission equipment provider that they will accept liability for any damages PoE for greater than 30 Watt applications The three different operations of how these “PoE” cameras are powered brings into question the value of using PoE for greater than 802.3at, 30 Watt applications. Value exists in the ability to centrally control power operations from a single accessible point. Certainly those cameras that are solely dependent upon PoE have the greatest advantage. This brings to the second point of confusion, the composition of the PoE power. To review a brief history, 802.3af (15.4) was the first PoE standard used for IP cameras and is for the most part a standard. 802.3at (30 Watts) was introduced as four different standards, two of which, Type 1 and Type 2 are supposed be compatible, but in reality are not. Transmission restriction over physical cables 60 watts has no standards. To understand this, we need to look at the limitations of transmitting power over physical cables. Any form of transmission over a physical media has limitations in the form of resistance. As resistance increases, so does the heat generated by this process. The higher the power, the greater the resistance and resulting heat generated. Based on CAT5e cable, a single wire can handle about 0.75 amps. In PoE transmission, power is transmitted on a pair of wires or 0.75amp X 2= 1.5amps. According to the 802.3at specifications, Class 4 specifications generally are considered to start around 48 volts. So we take 48 x 0.75= 36 watts or 72 watts for the pair. Dual PD (power device) system So how do we get to 60 watts? For “over” 30 watts, camera manufacturers use a dual PD (power device) system. In short, it operates as if it where two IP cameras and requires use of all four pairs within Cat cabling. Exceeding these power limits can be dangerous in overheating the cable and its installation. Therefore, any attempt to transmit 60 watt power over coax cable that is only a single pair should be considered with a great deal of caution, requesting from the transmission equipment provider that they will accept liability for any damages. The need to operate two PDs within a single camera is where the incompatibility exists. There are no standards as to the sequence of turning on separate PDs in a single camera The need to operate two PDs within a single camera is where the incompatibility exists. There are no standards as to the sequence of turning on separate PDs in a single camera. Most such camera manufacturers provide their own PoE source in the form of a PSE or camera power supply; however, don’t try to interchange these power sources among different cameras from different manufacturers as they will not work. If you attempt to use a third party version, make certain you confirm that the power source manufacturer has actually conducted certification testing and can provide proof of compatibility or provide any operational limitations. Distance of transmission Finally, there is the question of transmission distance. This takes us back to the physics of high-powered PoE transmission. Even with manufacturer-supplied PSEs, the distance limitation is still 328 feet (100m), the Ethernet standard. Most applications such as perimeter and parking lots will be hard pressed to find a power outlet within 328 feet of where the cameras needs to be installed. This is where third-party transmission equipment providers come into play, but again the ability of transmitting 60 watts PoE power for distances greater than 328 is more complex that standard 802.3af and 802.3at, and more limited. This combined with the non-standard make a detailed knowledge and interaction with the manufacturer critical to a successful installation.
Vanderbilt, a provider of the state-of-the-art security systems, announces new devices to complement the existing range of SPC Wireless system. The new range of devices include: WSIR-EXT – Wireless external sounder/beacon available with a blue, red, or orange beacon. WSIR-INT – Wireless internal sounder/beacon. WRPTR – Wireless AC plug style repeater to provide an alternative communications path. Wireless accessories – a range of accessories to improve the installation experience. Presenting a great revenue opportunity for installers We are pleased to announce the expansion of the SPC intrusion detection family" Wireless technology is coming of age, and the new Vanderbilt devices boast two-way wireless technology that delivers ease of installation without compromising on the security of a wired system. Commenting on the latest release, Ross Wilks, Head of Marketing Communications at the company noted: “We are pleased to announce the expansion of the SPC intrusion detection family with the release of these wireless devices. This range of products was designed in response to growing consumer IoT trends, and as a result, present a great revenue opportunity for installers in boosting their SPC portfolio offering.” Reducing costs for the installer Vanderbilt’s SPC Wireless devices are secure for installers to mount, pair, and configure, and they can cover over 500 meters in open space. This is a more cost-effective alternative than having to wire an entire building with cable. The 500-meter range cuts down on install time meaning a whole building can be fitted in just a couple of hours, offering a means of reducing costs for the installer. Paul Drillsma, Product Manager for the devices at Vanderbilt stated: “A vital feature of these releases is that the devices use the industry-leading lithium batteries, resulting in an extended battery life of five years or more. This longevity can free up installers’ time for more urgent tasks, as they won’t have to go to the site as often to keep changing out batteries.” Automatic power-saving mode This release marks the second phase of wireless development for the award-winning SPC system Battery life is a critical component of the SPC Wireless devices. An automatic power-saving mode supports them, and in fact, the SPC Wireless smoke detector, complete with EN14604 approval, comes with a battery life of over ten years. Further delivering on the aim of aiding installers, settings for SPC Wireless are all configurable over the air, again reducing the need for time-consuming site visits. Drillsma continues: “Installs for Vanderbilt's SPC Wireless devices were designed to be hassle-free. In contrast, a wired solution can take, at a minimum, a day’s work fitting cable. By reducing time on site, Vanderbilt’s SPC Wireless can enable installers to get more work done elsewhere, essentially meaning more profits from more jobs.” This release marks the second phase of wireless development for the award-winning SPC system. In subsequent releases due next year, Vanderbilt will also present repeaters for wired keypads, PIR cameras, and wireless keypads for their wireless range to the market.
GSX 2019 got off to a jaunty start Tuesday. The show was humming with activity much of the day, and most exhibitors said they were pleased with the numbers and types of potential customers visiting their booths. There seemed to be less emphasis on product introductions than at the ISC West show in the spring (although there is much that is on the new side), while the trend toward system sales is continuing. Here's a review of Day 1 from the show floor. Dahua continues to educate market “Traffic-wise, the show is better than last year,” observed Tim Shen, Director of Marketing at Dahua Technology USA, at midday on Tuesday. “We met more people from Latin America,” he added. Shen theorised that Chicago is at the center of a larger territory of customers than last year’s location (Las Vegas). Dahua’s presence at the show makes a statement: We’re still here" Dahua has faced some negative publicity in the last year since they were banned from procurement by U.S. government customers by the National Defense Authorization Act (NDAA). Dahua’s presence at the show makes a statement, says Shen. The statement is “We’re still here.” Shen said only one visitor to the Dahua booth even mentioned the NDAA on the first day of the show, and the visitor was misinformed about the provisions and implications of the law. “There is a lot of misinformation,” he says. “We need to continue to educate the market.” Facial recognition, video metadata, and people counting New at the show is the Dahua Analytics+ line of cameras that feature more in-depth analysis of data such as facial attributes, video metadata, and people counting. For example, the cameras can identify 128 points in a face, with an additional 256 attributes analysed by the back-end recorder. Analysis can provide information such as age and gender, which can help a retailer analyse the demographics of their customers, for instance. Dahua is also adopting some of its consumer line of products for sale through the commercial channel. These include a flood light camera, a 2-megapixel WiFi camera and a doorbell camera. The products might be used outside of a retail store, for example, to complement Dahua commercial cameras that are used inside the store, says Shen. Dahua previewed a new multi-sensor camera that also includes a speed dome. The multi-sensor component combines eight views, each 2 megapixels, for a total of 16 megapixels. Below the multi-sensor camera is mounted a speed dome that can zoom in on regions of interest in the larger multisensor view. The camera will be launched in the fourth quarter. The show was humming with activity much of the day, and most exhibitors said they were pleased with the numbers and types of potential customers visiting their exhibits ACRE report continued North American growth “The industry’s momentum will continue to grow,” predicted Joe Grillo, Principal of ACRE. New areas such as cloud and mobile credentialing have the fastest growth rate, but are starting from a much smaller base, he said, so momentum in those categories will take time. ACRE sees continued rapid growth with no slowdown in the North American market Grillo noticed the first morning of GSX was busy, although there was a bit of a lull at midday. In terms of the business outlook, Grillo sees continued rapid growth with no slowdown in the North American market, although there have been some negative elements creeping into the outlook in Europe. Cybersecurity concerns in access control I caught up with Grillo at the booth promoting RS2, a Munster, Ind., access control company that Acre acquired last May. It is the only Acre company that is exhibiting at GSX. RS2 is one of two access control companies acquired by Acre in the last year — the other was Open Options, Addison, Texas. Grillo said the two acquired companies are complementary, especially in terms of their sales channels and geographic strengths. Although both are national companies, RS2 tends to be stronger in the Midwest, while Open Options sales emphasis is centered in Texas and emanates to the rest of the country. Concerns about vulnerabilities are a growing issue in access control, said Grillo, and more large endusers are conducting penetration testing of systems. The industry should welcome the scrutiny, he added. Cybersecurity also represents an business opportunity in access control, noted Grillo. Concerns about the vulnerabilities of legacy technologies such as 125Khz proximity cards and the Wiegand protocol will likely accelerate the pace of companies upgrading their access control systems There seemed to be less emphasis on product introductions than at the ISC West show in the spring (although there is much that is on the new side) Eagle Eye Networks and cloud-based VMS Ken Francis of Eagle Eye Networks had already realised some new client opportunities during the first day of the show, although he was not optimistic at the outset. In contacting potential clients to meet at the show, he had heard that many were not attending. Among Eagle Eye Networks’ news at the show is full integration of body-cams into their cloud-based video management system. “It’s the most unique thing happening from a video management perspective,” Francis said. Previously, if someone needed a video clip from a body cam, they had to use a separate software system.Five years from now, at least 80 percent of all VMS systems will be cloud-managed" Francis continues to be bullish on the subject of cloud adoption of video management and made a bold prediction: “Five years from now, at least 80 percent of all VMS systems will be cloud-managed.” Eagle Eye Networks is doing its part with “rocket growth” that is reflected in an increase of company employees from 27 to 165 or so. Economies of scale have enabled Eagle Eye Networks to lower subscription prices by up to 45 percent. Genetec's release self-service PIAM system Many of the “new” products at GSX 2019 are slight variations on what was introduced at ISC West last spring. An exception is Genetec’s introduction of ClearID, a self-service physical identity and access management (PIAM) system that enforces security policies while improving the flow of people within the organisation. The new system is integrated with the Genetec's Security Center Synergis access control system. PIAM systems have historically been customisable, complex to install and costly, which is why a lot of companies have not used a system. Genetec’s differentiator is that it is an off-the-shelf, out-of-the-box solution for a broader base of customers. “We scanned the market and found a lack of off-the-shelf identity management systems,” said Derek Arcuri, Product Marketing Manager, Genetec. “Targeting the mid-market, we are providing an accessible, ready-to-go cloud-based system that is ‘baked’ for the average company but can be integrated and expanded to include other systems.” The trend toward system sales at the show is continuing ClearID will simplify operation for the security department, which was previously tasked with a lot of administrative work in response to various departments. ClearID “pushes down” the authority to use the system to stakeholders (such as IT and/or facilities directors) and provides a system they can use themselves without involving security. “It empowers stakeholders and employees to work directly through the system rather than going through security,” says Arcuri. “It gives employees access based on stakeholder policies and improves the flow of people through an organisation. The security director is relieved of administrative work and can work on ‘real’ security.” I saw some other things today, too, which I will share in a future GSX article... And more about the show tomorrow.
Fire and security systems are two elements of the same mission: To keep buildings and their occupants safe. However, the two systems often operate independently and may not be integrated. Should there be more integration and what are the pitfalls? We asked this week’s Expert Panel Roundtable: What are the challenges and opportunities of integrating security and fire systems?
