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.
Videotec presents NTX, the new IP68 stainless steel thermal camera, developed to provide an efficient and preventative surveillance system in the most critical environmental conditions. The NTX thermal camera offers temperature detection based on the 4 central pixels of the image, and with the advanced version, the temperature of a specific object can be measured at any point in the image by means of defining a specific area. As well as this, the radiometric functions offer the option to set a temperature limit, beyond which an alarm will be raised. Unwanted intrusions These functions are necessary where fire prevention is required or in applications such as monitoring industrial processes or critical equipment, where the ability to identify something quickly and accurately, thus preventing problems or failures and keeping intervention times to a minimum, is essential. Configuring and controlling thermal image parameters is possible via the ONVIF Thermal Service Standard NTX can export all the data necessary for a centralised management of video feeds, data and alarms, and make it available to VMS via the ONVIF Profile S and Profile Q communication protocols. Also, configuring and controlling thermal image parameters is possible via the ONVIF Thermal Service Standard. NTX allows exploiting fully the features and the advantages offered by the thermal camera. This includes the ability to raise an alarm and initiate immediate actions in order to prevent accidents or unwanted intrusions into monitored areas. Adverse environmental conditions The NTX camera is made entirely from electropolished AISI316L stainless steel and stands out thanks to its compact design and light weight. This, and the fact that it can be connected quickly, makes installation and maintenance easier. The modular support for wall, ceiling or parapet is supplied as standard. The NTX has obtained Lloyd’s Register Marine Type Approval certification for the maritime and naval sector and complies with the standard for railway applications. NTX is exceptionally resistant to corrosion and has a wide operating temperature range (from -40°C to +65°C). Its IP66/IP67/IP68, NEMA Type 4X and Type 6P grades guarantee maximum protection and optimal camera operation in even the most adverse environmental conditions. The fact that the NTX is extremely sturdy and of high quality means it is ideal for the most demanding applications in the marine and industrial sectors, in critical infrastructures, power plants and transport sector, including railways and motorway tunnels.

Building Information Modelling (BIM) can be described as the ‘use of shared digital representation of a built object (including buildings, bridges, roads, process plants, critical infrastructures, etc.) to facilitate design, construction and operation processes to form a reliable basis for decisions’. The National Institute of Building Sciences (NIBS) defines it simply as the “digital representation of the physical and functional characteristics of an object”. Understanding BIM construct BIM is neither a product nor software but rather is a “cache of building information” to which graphic data (such as drawings) and certain technical attributes (such as technical data sheets and associated characteristics) that are also related to the foreseen life cycle can be added. BIM represents a collaborative planning method as it allows for the integration of useful information for every phase of planning in a single model What BIM represents therefore is a collaborative planning method as it allows for the integration of useful information for every phase of planning – architectural, structural, plant design and installation, energy, management – into a single model. Project functionality and performance While CAD allows a project to be designed with 2D or 3D drawings, BIM also specifies the functionality and performance of each BIM object in the project or in the entire building process. A BIM object can hold any information pertaining to the building as a whole, or its parts. The most common information collected in a BIM is geographic location, structure, the properties of the materials/components/systems and technical elements, construction phases and maintenance procedures. Fields of application Building Information Modelling is used both in the construction sector, for design and installation (architecture, engineering, technical installations…) as well as in facility management. BIM supports the general improvement of a project along the entire life cycle of the construction process The role of BIM within the construction industry (by means of participants such as architects, engineers, surveyors, experts, builders, consultants and clients) is to support communication, cooperation, simulation and the general improvement of a project along the entire life cycle of the construction process. Advantages of BIM technology BIM technology offers a great number of advantages, such as greater efficiency and productivity, fewer errors, less downtime, reduced costs, greater interoperability, maximum information sharing, and more accurate and consistent control over a project. Generally, a BIM object is saved in .ifc (Industry Foundation Class) format. These IFC files are classed as 3D image files that also contain other technical information and are compatible with any software that works with BIM technology. Standard process and regulation BIM will become the standard process for all buildings and is currently being integrated into public contracts legislation across Europe. With Directive 2014/24/EU, the European Union has introduced a few guidelines to member countries on using the BIM system in the design and construction of public works. The BIM system is therefore strongly supported as a means of increasing the effectiveness and transparency of procurement procedures. Comparable BIM tools are necessary in order to allow the various softwares to ‘read’ the relevant data to manage all different parts of the construction sector Mandatory use of BIM process in public works In terms of the BIM process spreading to European operators (planners and companies), the leading nations are the Netherlands followed by the United Kingdom, whose government is bringing in a plan to make the use of BIM mandatory for public works. Even in Northern Europe and the United States, BIM technology has been used since 2000. Since the construction sector varies so widely (plants, structures, energy), it has become evident that no software exists that can manage all these different parts. Instead, comparable BIM tools are necessary in order to allow the various softwares to “read” the relevant data. BIM technology makes it possible to ascertain exactly how the cameras will fit into a building’s layout, reducing the risk of unexpected blind spots BIM and video surveillance Security has now become an integral part of the design process of any new large building. To provide the highest levels of security and avoid any blind spots that might constitute a security breach, the video surveillance system has to be planned in conjunction with other essential services, such as the electrics and hydraulics. BIM allows security system designers to interactively understand camera coverage, making it easier to identify the required models and to optimise the system layout. Reducing camera installation risks In actual fact, the technology makes it possible to ascertain exactly how the cameras will fit into a building’s layout (both internally and externally) and to determine whether the view of any camera is blocked by columns, lighting posts, trees, etc. This reduces the risk of unexpected blind spots. It is therefore possible to see how the cameras will be configured before they are installed, and which areas will be covered by the surveillance system after installation.
