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.
Vicon Industries, Inc., designer and manufacturer of video surveillance and access control software, hardware and components brings a new level of convenience and simplicity to its VAX Access Control solution with today’s introduction of mobile credentialing. This new feature allows VAX customers to present their smartphones, instead of cards or fobs, to specialised Bluetooth-enabled VAX door readers. Smartphone and mobile credentialing Upon installation of a custom smartphone “wallet” app and a simple authentication process that links that app to the specific phone, users enter their personal VAX credentials into the wallet. Multiple credentials can be accommodated. No additional activation steps, such as entry of personal information or Bluetooth linking, are required. To unlock doors using the mobile credentials, users unlock their phone, access the credential within the wallet app and push the “unlock” button. Credentials are uniquely linked to each smartphone and cannot be shared or installed across multiple devices. Android and iOS devices are supported. Strong AES encryption, combined with smartphone PINs or biometrics, make the mobile credentials even more secure than traditional smart cards. Two models of contactless door readers are available; one requires immediate proximity (1.5 inches) and one with read range of up to 15 feet. The Bluetooth readers can also accommodate traditional RFID access cards, providing flexibility to administrators wishing to offer both types of solutions to employees. Access Control Bret McGowan, Vicon’s V.P. of Sales and Marketing, says, “Access control is as much about convenience as it is security. If a solution isn’t easy for customers to use, doors will remain propped open and the system can’t do its job. Our new mobile solution makes it possible for employees to always have their credentials with them, even when they’re not carrying a purse or wallet. It’s another way we are using cutting-edge technology to deliver ‘advanced simplicity’ to the security marketplace.”
Vicon Industries, Inc, designer and manufacturer of video surveillance and access control software, hardware and components, announces that its SN673V-B Cruiser PTZ Camera with 20X optical zoom and 1080p HD video has been deployed in Charleston Harbor, South Carolina, as part of the Coastal Conservation League’s novel project, ‘The Pelicam.’ The Pelicam is a weather-resistant Vicon camera, mounted on a pole along with solar panels, battery back-up and a wireless transmission system, on an isolated strip of land within the harbor. Wray Lemke, Founder and Vice President of electronic and security services company Mount Pleasant Radio, volunteered his time to bring this project to fruition. Conservation league The Pelicam’s location is a popular spot for pelicans and other shore birds to build nests and raise their young because it is inaccessible to raccoons, coyotes and other natural predators. The Vicon camera’s 20X optical zoom provides close-up video of the birds, allowing biologist from the Department of Natural Resources (DNR) and the public to witness behaviours that would not normally be observable by humans. Conservation League makes use of the camera’s presets to quickly change between scenes, live-streaming on YouTube video of the most interesting wildlife The Conservation League makes use of the camera’s presets to quickly change between scenes, live-streaming on YouTube video of the most interesting wildlife on display at any given time. Video recorded to the camera’s local SD card is available for DNR biologists to review and study. Andy Hollis, Data and GIS Analyst for the Conservation League, says, “The quality of the new camera is great. It pans and zooms exactly as it should and its high magnification gets us in really close.” Building public awareness In addition to supporting the research needs of the DNR, the Pelicam is hugely popular within the community, garnering regular coverage in the local media and receiving more web traffic than any other page within the organisation’s website. Mr. Hollis explains, “As an advocacy organization working with local and state level government to enact programs and laws to support conservation, the Pelicam is one of the most highly effective tools we have for building public awareness and enthusiasm for our mission.”
Vicon Industries, Inc., designer and manufacturer of video surveillance and access control software, hardware and components, announced the launch of Valerus 18.2, the latest version of its popular thin-client VMS solution built upon true open standards. New to this release are features that include: automated NVR failover, enhanced configuration options that include an enhanced rules engine that can respond to external events, tighter controls for system access authorisations and network-wide log collection and reporting. It also offers support for Valerus SmartAnalytics, a soon-to-be-released, tightly integrated video analytics solution that offers real-time event detection, video search and business intelligence applications. Valerus’ new NVR failover option allows administrators to create ‘failover clusters’ within the network, in which one or more NVRs are identified as dedicated failover units to support primary NVRs. Failover NVRs automatically take over for primary NVRs within their cluster, maintaining all camera and system settings until the original NVR is restored to operation. Playback of recorded video remains seamless, eliminating the need for operators to know exactly when failover occurred. Valerus automatically retrieves video from the NVR on which it resides. Valerus SmartAnalytics for event detection Valerus SmartAnalytics can analyse video from multiple sources in parallel and allows for complex detection scenarios that link detection rules from different cameras The addition of Valerus SmartAnalytics as an option for users of Valerus 18.2 brings powerful, integrated analytics capabilities to the VMS platform. The Valerus SmartAnalytics engine applies detection rules based on sophisticated AI algorithms to provide live action alerts, post-event search and business intelligence trend analysis. Valerus SmartAnalytics can analyse video from multiple sources in parallel and allows for complex detection scenarios that link detection rules from different cameras. Unlimited combinations of analytics detection rules can be applied to each camera. Events and search tools appear within the Valerus interface, providing a simplified experience for system operators. Both NVR failover and Valerus SmartAnalytics support are offered through a new ‘enterprise’ level Valerus licensing tier. The Valerus SmartAnalytics modules will be available to customers running Valerus Enterprise, version 18.2, beginning in early fall, 2018. Customers currently running Valerus Pro or Core level software can easily upgrade to Enterprise without the need for camera relicensing or hardware replacement. Improving security staff’s situational awareness In keeping with the Valerus commitment to delivering ‘advanced simplicity’, Valerus 18.2 offers a simplified but more powerful system configuration user interface. Administrators can now use the Valerus rules engine to create multi-step automated actions in response to events generated by external systems. Administrators must now actively provide each user with access to Valerus resources by assigning him or her to one or more ‘roles’ – Admin, Operator, Supervisor and/or Investigator For example, an integrated LPR system’s identification of a black listed vehicle can prompt Valerus to immediately call up relevant cameras and send a text alert to specified operators, improving security staff’s situational awareness and ability to respond quickly. The configuration interface now simplifies load balancing, making it easier to move cameras between NVRs, and provides additional navigation buttons for jumping between the device and resource screens. Enhanced security through authorisation system Valerus 18.2 offers enhanced security through an updated authorisation system. Administrators must now actively provide each user with access to Valerus resources by assigning him or her to one or more ‘roles’ – Admin, Operator, Supervisor and/or Investigator. Assigned roles determine which resources are available to each user upon logging in. For support and maintenance teams, a single request can now provide system-wide software logs from all devices, making it easier to troubleshoot. “Vicon’s Valerus VMS platform has proven to be hugely popular in enterprise applications, from citywide and statewide surveillance systems, to healthcare and education campuses, to the largest Cathedral in the world. We anticipate that the features we are introducing with Valeurs 18.2 will do much to further that trend,” said Bret McGowan, Senior V.P. of Sales and Marketing.
