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.
The Danish Superliga football club Brøndby IF were aware that family attendance had fallen at some of the more high-profile games, such as the local derby with F.C. Copenhagen, due to concerns over hooliganism and safety. With an average attendance of 14,000 people per game, and up to 100 registered persons on the stadium blacklist for causing trouble, the football club wanted to find a way to make genuine fans feel safer by preventing problems before they could occur. Improving security With the use of cameras and facial recognition, blacklisted offenders can now be automatically identified in the crowd before they attempt to enter the stadium. This system identifies any individuals registered on the offenders list and alerts security staff to prevent them from entering. The automated procedure at the stadium entrance also decreases congestion at the gates, so genuine fans can get into the stadium faster. As well as improving security outside, the system allows staff more time to focus their attention on creating a safe and entertaining environment for those inside the stadium. The technology can identify faces that are difficult to recognise with conventional techniques Facial recognition server The Panasonic facial recognition software ensures high levels of accuracy. The technology can identify faces that are difficult to recognise with conventional techniques, such as those taken from an acute angle and even when part of the face is concealed or hidden by sunglasses or scarves. In fact, the National Institute of Standards of Technology (NIST) in independent testing identified the system as the most accurate facial recognition server on the market. And the system is already working. One blacklisted offender was prevented from entering the stadium at the very first home game of the season in mid-July and he will receive a fine and extended ban. Protection of personal data However, some fans were initially sceptical about the scheme. They were worried about the Big Brother concerns of privacy and personal data protection. These fears quickly faded once the club explained the sensitive way that the scheme had been implemented. Security personnel remain in control of the process at every stage. The technology flags potential blacklisted offenders and the security advisers then take over and investigate further before taking action. People-led and technology supported The solution is people-led and technology supported. Personal data privacy is also protected because the facial recognition technology does not store the images or data of any supporters, other than those registered on the blacklist. In addition, all personal data is stored on an internal server, not connected to the internet or to any other system, significantly reducing any cyber risk of data breach. After seeing the results of the technology and receiving reassurances about data protection, both Brøndby management and fans alike have welcomed the new technology. Moving forward there is also the potential to utilise a national hooligan register with the system to help spot travelling troublemakers within Denmark.
Danish Superliga football club Brøndby IF’s stadium is the first in Denmark to utilise facial recognition technology, provided by Panasonic, to ensure a safer stadium experience and alleviate the strain placed on staff during high profile matches. Panasonic security cameras The system is being deployed to automate the process of identifying blacklisted persons and prevent them from entering the stadium, a task which was previously undertaken manually by security personnel. Panasonic’s security cameras and FacePRO facial recognition software, automatically identify any individuals registered on the list, and sends a message to staff to take the appropriate action. The automated procedure at the stadium entrance will decrease congestion at the gatesThe system will enhance security measures and fan safety, which will prove especially important during high profile matches such as the derby against F.C. Copenhagen. Furthermore, the automated procedure at the stadium entrance will decrease congestion at the gates, resulting in a faster entrance process for fans. Stadium security Expecting an average attendance of 14,000 people per game, and up to 100 registered persons on the stadium blacklist, it allows staff to focus their attention on better assistance and service towards fans entering the stadium. Jesper Jørgensen, Managing Director of Brøndby IF commented, “The system will significantly increase our efficiency in identifying blacklisted persons at our entrance gates, so we can ensure they do not enter the stadium. We are always trying to optimise our stadium experience for our fans, and ultimately create the best possible fan experience. This is another step into the right direction.” FacePRO facial recognition software To maintain personal privacy, the facial recognition technology does not store the images or data of those who are not registered on the blacklist. Also, the data of those who are registered on the internal Brøndby server is not connected to the internet or to any other system. Panasonic’s facial recognition system contributes to a safer stadium environment by alleviating security pressure" “Panasonic’s facial recognition system contributes to a safer stadium environment by alleviating security pressure on the ground, while ensuring that all data is protected from unauthorised external access” said Gerard Figols, head of the European security business at Panasonic. “In turn, we can offer peace of mind to football fans and Brøndby IF that our technology will improve the standard of safety even during high profile matches, something that fans have already complimented the system for.” High-performance facial recognition Recognised by the National Institute of Standards of Technology (NIST) as having the world’s highest level of facial recognition performance in independent testing. The technology can identify faces that are difficult to recognise with conventional techniques, such as those taken from an angle of up to 45 degrees to the left or right or 30 degrees up or down, and even when part of the face is concealed or hidden by sunglasses. The system also recognises faces from photographs that are up to 10 years old.
