The advantage of H.265 Camera

H.265 / HEVC is the latest video compression standard which is based on H.264, driven by ever increasing demand for high definition and the rapid development of imaging technology, UHD becomes trend in today's television and video surveillance market. UHD standards for ultra high definition includes 4K UHD and 8K UHD. 4K UHD equals 3840 x 2160 (approximate 8.29 megapixels), while 8K UHD equals 7680x4320 (approximate 33.18 megapixels). 
In today's video surveillance applications such as parking lot, hotel, safe city, harbor, air port and elsewhere large scaled and has growing demand on detail capturing, which, at the same time, pressuring on decoding and storage. Apparently, the introduction and development of H.265 standard brings extensive possibilities and optimism to the industry by addressing problems such as shortage of bandwidth, improving transmission efficiency and delivers other benefits.
In order to solve the high bandwidth problem for ultra high definition, the Moving Picture Experts Group (MPEG) developed the H.265/High Efficiency Video Coding. Compared with current mainstream H.264/MPEG-4 AVC, the H.265 is able to double the data compression ratio, while improve video quality with low bit-rate. The H.265 supports both 4K UHD and 8K UHD resolution up to 8192x4320. In conclusion, H.265 is capable of further reducing 50% the data rate requested for high quality video coding. Bitrate is acclaimed to have approximate 40% to 50% down at 1080p while rendering superb image quality.  This enables IP camera to deliver smooth video with low bandwidth, which in turn, reducing the network bandwidth, and video storage size. Meanwhile, with the rapid development of 4G cellular mobile technology, the integration between the H.265 and 4G will have much possibilities.
HEVC/H.265 mainly features in the following aspects:
·         Higher compression efficiency, when compared with H.264/AVC. In same resolution, HEVC/H.265 has lower bitrate than H.264/HEVC.
·         Support high definition, ultra high definition video formats
·         Support frame rate of 20-60 frame per second video decoding, has same flexibility like the H.264/AVC, supports maximum 172fps.
·         Friendly network adaptation.
As leading and innovative corporate, Hisilicon and Ambarella can't resist its charm and prospect, both of them introducing the first H.265 SoC for ultra high definition IP cameras. Despite the reason that H.265 is still a new compression standard to video surveillance industry, the security camera manufacturers such as Hikvision and Dahua have already adopted H.265 in their latest product portfolio, including ultra high definition network camera, NVRs.
To start with cameras, Hikvision has a latest-released 2 megapixel H.265 low light smart camera DS-2CD5026FWD-(A)(P). As H.265 camera, the Darkfighter series ultra-low light Smart cameras are able to capture high quality colored images in dim light environment. DS-2CD5026FWD offers Full HD resolution with up to 60fps high frame rate, 120dB WDR, Auto Back Focus, P-Iris, PoE, 3D DNR and complete Smart Feature-set to meet a wide variety of applications. It supports H.265/H.264/MJPEG dual video compression, allowing over 40% lesser bandwidth use while acquiring outstanding image quality. Moreover, with its functions such as Intrusion Detection, Line Crossing Detection, Scene Change Detection, Audio Surge Detection, Audio Loss Detection, Defocus Detection, Face Detection, etc.
On video storage perspective, Dahua and Hikvision introduced a comprehensive H.265 4K NVR product lineup, which covers different demands from small to medium as well as large scaled applications. These network video recorders have capability to support up to 12 megapixel recording capability, supporting 1080p@60fps and H.265 preview and playback; 4 channel 4K resolution real time live view and playback; meanwhile, the NVR has many intelligent functions including smart video analysis, facial detection, privacy mask.

Simple Ways to Clean your Camera Lens

Three Simple Ways to Clean your Camera Lens

Dust, rain, and bugs can have a great impact on the quality of your camera’s picture, but with the following easy tips, you can keep the image quality looking great throughout the life of your security camera.
1. Distilled Water – Put some distilled water into a squeeze bottle with small tip. You’ll want to gently apply some water droplets, and then blot gently with lens tissue or another clean, lint-free, scratch-free material.
2. Baby Shampoo – A mild surfactant like Johnson’s baby shampoo (diluted with water) lightly applied to the glass and blotted dry is a great way to remove dust, spider webs, and oil compounds from areas that create steam from oil based foods.
3. Hot Air – By using a hair dryer to a dry lens you are heating up the glass to a point where the molecules are now looser and easier to remove.  The reason why waxing a car is such a chore is the effort needed to create heat by rubbing the surface to warm up the compounds so they can be removed.  A simple hair dryer to a lint free cloth can do the trick for minor cleaning needs.

Android Lollipop vs. Android KitKat

Android Lollipop vs. Android KitKat
Android L is a HUGE update that sees Google taking its already mature platform several steps further. The Big G has tightened up nearly every element of its mobile platform, refining the look and feel of Android across the board, as well as touching up back-end tools and protocols to make the platform even more efficient.


Android 5.0 Lollipop has now launched officially and will be initially available on a brand new Nexus 6 phablet and Nexus 9 tablet. Motorola will be next to follow up with the updates and then soon we expect news from Samsung, HTC, Sony and all the rest. HTC revealed they are planning to bring the new update on their flagship smartphones – One M7 and One M8 – within 90 days after the Google makes the final code available. A new report reveals when the Taiwanese phone maker plans to bring the Android 5.0 Lollipop update for HTC One Mini 2 and Desire 816.

Android 5.0 Lollipop vs. Android KitKat: Material

Android Lollipop is the biggest change to Android in some time, finally bumping Google's OS up a full integer to version 5.0.
It's packed with changes, but the most obvious improvements are visual.

Google's been working on getting its new "Material Design" aesthetic out in the world for months, and Lollipop is its culmination. One of Android's biggest failings up to date - including with KitKat - has been that its design language never felt unified, and with Material Design Google hopes to fix that.
The aesthetic is meant to look both flat and 3D, as if you're starting at animated paper that exists on a z-axis as well as the x and y.
Material Design reflects this with clean, bold lines and colors that transform and alter with fun animations. At its best it lets you sense the depth behind the interface, even when it's at rest and appears flat.
This extends from app icons, fonts and interfaces to simple elements like the new navigation buttons and notification bar icons, and once you get past the changes you'll likely agree that most things look better now.
The changes to Android's interface with Lollipop aren't all visual, either - voice commands with "OK Google" are more prominent now as well, and can even be used when the screen is locked and off on some devices, and there are massive improvements to notifications.

Android 5.0 L vs. Android KitKat: Notifications 

Notifications have been Android's strong suit since day one, and Google is making them even better in Android Lollipop. The big change here is that they're being integrated into the lock screen – something Google previously experimented with when it developed lock screen widgets which allowed you to view emails and events without actually unlocking your phone.
As well as making notifications the first thing you see when you pick up your handset, Google is working on making them smarter when the phone is in active use. For example, in KitKat a call would totally interrupt whatever activity you were involved in, be it reading a book, browsing your emails or playing a game. In Android Lollipop, events such as these will pop up at the top of the screen, a la Samsung’s Galaxy S5, meaning you can choose to jump to that event or ignore it with a quick tap without leaving your current task.
Compared to Android 4.4, notifications are going to be smarter, more intuitive and less intrusive than before. KitKat's notifications system is decent enough, but it was basically recycling what had come before, so it’s good to see some out-of-the-box thinking from Google in this respect.

Android 5.0 L vs. Android KitKat: Security

Google has made massive strides with Android when it comes to overall security, coming up with innovations such as pattern unlocks and facial recognition. KitKat didn't bring much new to the table in this respect, but it worked well enough. Android Lollipop's big advance is going to be about making security more convenient, and it will do this using two methods: Android Wear and your current location.
In the first case, you can use your shiny new Android smartwatch as an authentication tool to automatically bypass your phone's passcode when it detects the watch nearby. In the second example, you can designate safe zones – your home, for example – where your phone will switch off your lock code. While both of these features could potentially create a security risk, if someone steals your phone and your smartwatch, they have access to all of your personal data, for instance, but they will overcome the irksome issue of having to continually unlock your device every few minutes.

Android 5.0 Lollipop vs. Android KitKat: Battery Life

Project Butter was Google's way of making Android feel smoother and slicker, and now the company has revealed Project Volta – a system which will provide developers with a better means of determining what elements of their apps are draining battery at an unnecessary rate. Because Volta will open up the battery stats to devs, they can tinker with their code to make apps more efficient and spot potential problem areas.
Android Lollipop will also take a leaf out of HTC and Samsung's books by coming with a battery saving mode by default. This will help users get as much mileage out of each charge as possible by throttling certain functions when juice is low. Such improvements will ensure that Android L is leaps and bounds ahead of KitKat, which only offers basic stats on what process is gobbling up the most power.

Fishy Incidents — Industry Perspectives

Spot the fishy incidents — 10 perspectives from the industry

Panoramic fisheye cameras have seen fast growth in the surveillance industry. With the key feature in surround view monitoring and the advantage in reduction of installation cost, they are becoming the popular adoption in security system. With a promising market ahead, differentiation of product and market strategy from competitors is the way for major manufacturers to think when planning next moves.
EU and US regions
We here presented 10 worldwide providers from the security industry – VIVOTEK, Sony, Axis Communications, Hikvision Digital Technology, Samsung Techwin, Dahua Technology, Merit LILIN, EverFocus Electronics, Panasonic System Networks & AMG System.
Asia regions
VIVOTEKTaiwan
“The 360-degree cameras can be especially ideal for intercom or retail applications. Retail stores especially demand for a cost-effective and comprehensive surveillance system, which dissuades shoplifting and pickpocketing,” said Steve Ma, Executive Vice President of VIVOTEK. “With several unique features and wide surveillance coverage that can be delivered by the 360-degree fisheye camera under complicated environment, retail stores tend to deploy 360-degree fisheye camera the most.”
“The deployment of 360-degree fisheye cameras could be financially and technically beneficial. It is worth to note that just one 360-degree fisheye camera can deliver the same coverage as 6 to7 cameras that have been used in the stores. With the installation of panoramic models, the total number of cameras needed by the clients can be significantly reduced,” explained Ma.
VIVOTEK has made our fisheye camera as a pro-active smart sensor through our superior algorithms, making fisheye cameras performing intelligently, like people counting, field detection, trip wire, according to Ma. “With the technology evolvement and rising awareness of cost-effective solutions, the prevalent adoption of 360-degree fisheye camera for wide open area surveillance in the following years is foreseen. In addition, a 360-degree fisheye camera with intelligent capacity is undoubtedly to be a trend.”

SonyJapan
“With its multiple security benefits and associated cost savings for end users, it is easy to understand why the 360-degree security camera has been highlighted by IHS as one of the key drivers for the video surveillance camera market in 2014 – which is slated for double-digit growth this year. Sony also recognizes the importance of these cameras in addressing the ever changing security environments of the modern world, and will continue to advance in the 360-degree security camera market with our end users,” said Riki Nishimura, General Manager of Visual Security Solutions, Professional Solutions Company (PSAP) at Sony Electronics Asia Pacific.

AXISSweden  
“According to IHS Research, sales of network video start to overtake analog in 2014 due to the powerful functions of advanced video processing and analytics. This is especially true in the retailer sector, as 360-degree cameras allow for an overview of all activities in a given area while being affordable for users having to work with tight-budgets in for example the retail and education sectors,” said Petra Bennermark, Product Manager at Axis Communications. 
“In a study by Axis Communications, more than half (58%) of UK retailers are planning to migrate from analog to network video in order to integrate network cameras with business intelligence (BI) applications. BI application integration was considered the most significant reason for UK retailers to move to network video.”

HikvisionDigitalTechnologyChina
“Normally, SMB users may tend to use entry-level fixed cameras instead of panoramic cameras, since the latter are mainly targeted for middle-to high-end project use, and price are relatively higher. Therefore, Hikvision plans to introduce economical mini panoramic cameras to penetrate into SMB market in the middle of this year,” said Adler Wu, Product Marketing Manager of Hikvision Digital Technology.
“And for Hikvision, we forecast to increase at an annual growth rate of 60%-70% [before 2017], according to our company strategy, product planning and the market development. Panoramic camera would develop in two different ways in the future, one for SMB adoption and the other for high-end application. With more and more manufacturers joining in the competition, the price of panoramic camera may decrease to a level, allowing the cameras to enter SMB market; for high-end use, due to the wide coverage of panoramic camera, more images/ scenes could be achieved compared to common IP camera. Therefore, how to well make use of this advantage could be a breakthrough to eventually benefit the end users.”
“Considering lots of manufacturers have introduced their panoramic cameras, it becomes very important for us to provide innovative products to differ from the others at this stage.”

SamsungTechwinKorea 
“360-degree cameras are increasingly being specified for projects where there is a requirement to monitor activity 24/7 in environments such as banks, offices, retail, transportation and warehouses. The advantage they offer is that a single 360-degree observational camera is all that might be needed to efficiently and cost effectively covers a whole area where a much larger number of standard cameras might normally be required, to avoid any blind spots,” suggested Tim Biddulph, Product Manager of Samsung Techwin Europe.
Samsung Techwin's 360 degree camera is part of the company's extensive range of IP network cameras. Tim Biddulph emphasizes the importance of fully understanding clients' needs first, before endeavoring to persuade them to migrate to 360-degree or other products and technologies.

DahuaChina  
Fisheye cameras are mostly deployed for indoor surveillance, getting more and more popular in public buildings, pointed out by Peter Pan, Product Manager from Dahua. Seen as the economic choice for security system deployment, one single fisheye camera can achieve wider coverage of monitoring than other non-panoramic camera.
This is even true to public units, hotels, and schools. They often have budget concerns; theses users are not too demanding in security image details while their purpose of surveillance system is mainly for prevention, Pan suggested. 
“At present, many surveillance camera manufacturers have proposed new thoughts of design,” he continued. Currently, end users start to use 360-degree cameras and PTZ speed domes altogether, featuring both wide-coverage and detailed monitoring views. The 360-degree cameras are going to become an essential solution in surveillance systems, according to Pan. 
“Although fisheye cameras are expecting fast growth in the near future, the 360-degree cameras won't become the majority in surveillance camera market due to their own pitfalls such as low pixel counts at the edge of images, and image distortion,” explained Pan.
However, as Pan mentioned, the technical improvement related to these pitfalls has been essential to manufacturers in the industry. Meanwhile, some manufacturers have started enhancing camera capacities in IR support for advanced day/night monitoring.

MeritLILINTaiwan
“Fisheye cameras are all about seeing everything in a scene more efficiently than with multiple cameras; therefore, providing security managers the ability to cover an entire scene in a logical way without gaps of coverage is prominent,” according to Chris Hsu, Global Marketing Manager at LILIN. “LILIN panoramic IP camera is an ideal choice for open-ended lobby areas such as entrances, exits, and lobbies.”
“The current leading technology trend in global market is ‘less is more'. We expect cameras can cover a range of area such as 360-degree fisheye camera is an ideal all-in-one product will definitely continue to shine in the following years.”

EverFocusElectronicsTaiwan
Douglass Wang, Deputy Project Manager of EverFocus Electronics, emphasized the importance of fisheye and speed dome cameras' synergy, combining advantages from both types of cameras, and adding value for wide-area surveillance without compromising the optimal image quality. “The end users can finely utilize pan, tilt, and zoom functions on speed dome to keep tracking region of interest, while monitoring the entire area through 360-degree camera view, more importantly, without any blind spot,” Wang said.
As panoramic camera is favored to be applied with speed dome in areas such as airport, warehouse, public space, and parking lot, end users might hesitate due to complicated cameras configurations. “EverFocus provides end users a 4-steps image calibration which dramatically reduces configuration time,” Wang highlighted.

PanasonicJapan 
It is forecast that a growth of more than 50% will be seen in the panoramic camera market – more than current security market trend expectation – as higher image resolution will expand the deployment and acceptance of fisheye camera in more vertical markets, commented Akihito Akiyama, product planning manager at Panasonic.
According to Mr. Akiyama, Panasonic has strengthened its 360-degree cameras by continuingly progressing at technology development, including dewarp, super dynamic function, and vandal resistance. With the solid technical base, the 360-degree cameras are capable for high-resolution image quality with even edges, stable performance under various lighting environments, and last but not least, durability.

AMGUK  
Fisheye cameras, compared to other types of cameras, offer a number of key advantages — monitoring of surround view without blind spot and reduction of installation cost and work — whilst still keeping high-resolution recording quality, David J. Myers, Technical Director of AMG, highlighted. AMG have noted that 360-degree fisheye cameras are becoming the mainstream when analog CCTV is gradually replaced by IP CCTV systems. 
“We are not sure that there is one particular market deploying the most 360 degree cameras. In the USA, the retail market is strong. And transportation is a natural market for wide-angle camera when one single camera can cover whole view of a bus, or a train carriage,” Myers said. “Banks, schools, colleges, museums, and public buildings are also the target market of 360-degree cameras. So are car parks and outdoor perimeters.”
