HD Video Surveillance cameras create big data deluge

HD Video Surveillance camera usage is increasing day by day and is leading to an extraordinary deluge of data in the surveillance field. Currently, surveillance cameras on a global note generate around 413 petabytes of data each day and this will rise to 859 petabytes in 2017 due to the proliferation of HD Video Surveillance Cameras.

Innovations in HD Surveillance across IP networks are creating opportunities to integrate more intelligence into cameras so that the video footage can be captured, analyzed and tagged in real time.

As per the latest survey results disclosed by IHS, the shipments of HD cameras is continuing to rise and is expected to double up in next four years. Thus, this technological trend predicted by IHS will automatically promote the use of technologies that are designed to handle and process big data in the surveillance field.

Again as per IHS’s latest prediction, law enforcement officials are among the best benefactors of this trend. In recent years, many major cities have started to invest in HD video surveillance technology to maximize public safety. Example, the New York Police Department, has an IP video surveillance network that synchronizes 3000 HD security cameras with license plate readers, radiation sensors, criminal database and terror suspect list. The other best example is Washington DC Traffic Police Department which ranks number one in US in surveillance with thousand of camera installations in high traffic areas.

Therefore, video surveillance business is adopting several technologies designed to accommodate and mitigate in order to deal with big data deluge. The first technique is addition of new data compression algorithms in order to cut down the data storage capacity limits. For example, High Efficiency Video Coding standard also known as H.265 has been claimed to double the data compression ratio when compared to the current H.264 codec algorithm. This will automatically reduce the amount of data produced per camera in next few years.

The other promising development is Video Content Analysis (VCA), where the amount of time in recording can be reduced with the use of virtual tripwires and no-entry zones. That means only important events will be captured by the security cameras, rather than wasting recording resources with continuous recording of events. So, if VCA implementation increases reduction in the amount of data produced per camera can easily be observed.

The other final area which needs innovation is the increase in storage capacity of hard drives used in video storage and video management engines dealing with HD cameras. Already, HDD makers are coming up with hard drives with increased capacities. The latest is 6TB hard drive with and without the use of Helium gas in place of air. Seagate, and WDs HGST have already presented these high capacity drives to the surveillance market and their adoption will increase in coming days as per the needs.

Therefore, though the usage of HD surveillance cameras will lead to big data deluge, if cleverly managed, it can be curtailed.

Google and Facebook confirm eyeing drone business

Google has officially announced that it has purchased solar drone maker ‘Titan Aerospace’ for an undisclosed amount. This cements the online rumors that Google will use these solar powered drones to offer internet connectivity to remote places in order to propagate its web services to new folds.


The point to be noted over here is that till last week, Facebook was also planning to lock a deal with Titan Aerospace, a New Mexico drone maker of solar powered drones that basically function as satellites some 8 miles above in the clouds. But for some reason, the deal could not be formularized and went into the hands of Google.


According to the latest reports, Titan Aerospace will start provided drones from early 2015, which will have a wingspan greater than Boeing 767. These wings will carry solar panels on top of them, which will keep them aloft for 5 full years at a time. Named as Solara 50 and Solara 60, Google will be using these drones to cover 2.8 million miles with a field of view of more than 25,000 square miles in order to deliver its web services to remote places. As per the reports available on hand, Titan Aerospace will be producing such solar drones which are pilotless and can deliver internet speeds of up to 1GB per second.


Coming to Facebook’s plans, with its Titan Aerospace deal getting into Google’s hands, there is a high probability that the social media giant will be looking to sign a deal with Ascenta, which is another solar powered drone maker in May 2014.


So, with these two web giants planning to use solar power drones to connect remote areas, an eventual increase in their user base will be witnessed in coming years.

The need for a Scalable Storage in Video Surveillance

IP Video Surveillance systems popularity is rising day by day and that is bringing a major revolution to data storage needs in surveillance field. Today’s video surveillance systems need storage that can

  • Scale to larger storage capacities when needed
  • Can have the ability to record higher frame rates without missing a single frame
  • Can prove cost effective for needs pertaining to longer retention period
  • Has the ability to handle higher resolution video from megapixel and multi-megapixel cameras
  • Can allow a surveillance manager store and manage the recorded videos centrally from a distributed implementation

Thus, with the increase in storage needs, many organizations (having IP video surveillance systems and hybrid systems incorporating both analog and IP cameras) are considering Storage Area Network (SAN) as the best medium to quench surveillance related storage requirements.

A SAN is a dedicated network storage which can be connected to numerous storage resources such as DVRs and NVRs. When connected, it will act as a centralized single storage with shared arrays. As a result of this arrangement, a network host such as a DVR or an NVR will see the remote storage server as if it were a locally attached drive and transfers information in blocks as if it was accessing the local hard drive content.

So, for big surveillance projects which involve 300 – 500 IP and analog camera deployments (such as in airports, rail networks), a scalable SAN storage will be a perfect centralized solution to consider.

Currently, Fibre Channel (FC) technology and iSCSI are the dominant protocols used to connect SANs. If in case high transfers of block data is required, then FC SANs are the best to consider, provided you should also bear with the high costs involved in this SAN infrastructure lay out, as a separate and dedicated network line has to be laid out.

For cost effective storage needs, Internet SCSI is now an industry standard developed to enable transmission of SCSI commands over existing IP network by using the TCP/IP protocol. Accordingly, with the help of this technology both messaging traffic and block based storage over existing IP network can be achieved.

Coming to benefits of having an IP SAN, an IT Manager can virtualize hundreds of physical disks and present itself to an NVR as a single logical drive which can be represented with a single drive letter. Also, since all these drives are protected with RAID technology, utmost redundancy can be achieved based on different RAID configurations.

Hence, with a SAN storage usage in surveillance; availability, resiliency and scalability can be easily achieved. Moreover, these kind of IP SANs can not only solve challenges like reliability, retention and resolution issues seen in traditional DVRs, but can also offer a scalable storage with all the above said specifications in NVR deployment as well.

A SAN such as DNF Security SkyHawk Unified Scale Out Series of appliances can enhance video storage performance through video surveillance workload optimization. With this appliance, the user can get a fully featured IP SAN and Scale Out NAS, all in one easy to manage appliance. This solution was exclusively designed for applications which need scale out storage capacity without any compromise in performance.

Box Cloud Storage servers are free from Heartbleed Bug

California based BOX IP Storage provider founded in 2005, has made an official announcement that it has patched the Heartbleed security hole on its servers and has strongly suggested that to all its users to turn on the two-factor authentication and go for strong passwords.


Box also added in its announcement that there was no indication that it was been targeted or attacked in relation to this bug and has assured to its users that there was no malicious activity on its servers till date.


Last week, online reports suggested that a bug named Heartbleed was discovered on most of the servers of many major web service providers and was existing from the past two years.


According to a report published in The Wall Street Journal this bug was existing on different servers of various web service providers from the past two years and NSA Prism Program was witnessing this whole vulnerability like a tennis fan watching a US Open. For some reason, it never alerted the service providers till date and that reveals how much advantageous Prism’s existence was proving.


Box has around 25 million registered users and around 2 million of them are accessing its premium services. Out of the said number, 34,000 in number are corporate customers, out of which 40% of them are Fortune 500 and 20% of them belong to Global 2000 Companies.

Heartbleed bug presence can expose private server encryption keys

Heartbleed Bug presence on a private server could expose the server’s encryption keys and this was discovered by four researchers who separately did some research on this issue. The research was carried out, when a San Francisco based Security Company CloudFare challenged the security community to see whether a flaw in OpenSSL Cryptographic library can be tracked by hacking the encrypted channel between users and websites having SSL/TLS security layers.

Getting deep into this challenge, four researchers have discovered that all those servers loaded with Heartbleed could expose what Cloudfare is expecting.

Note- A Private key is nothing by a security certificate that verifies a client computer is not connecting with a website which isn’t real in all terms. Only those certificates which are genuine are returned onto the browser by the server. Therefore, browsers indicate the legitimate connection with a padlock and show a warning if in case the certificate is invalid and in some terms expired.

In this research it was revealed that an attacker could set up a fake website that passes the security verification, just by obtaining a private key for Secure Sockets Layer/Transport Security Layer certificate. Adding more, a hacker could also easily decrypt traffic passing between a client and a server and can also unscramble the entire communication correspondence.

It was revealed in this research that a Heartbleed bug can divulge data in 64K batches from a computer memory and this includes all the login credentials of people who have recently logged into the server. The research initiated by CloudFare is in progress and researchers are trying their best to find out what type of data can be revealed.

The four researchers who are exploiting the server vulnerability by the presence of Heartbleed bug are Rubin Xu, a doctoral student at Cambridge; Ben Murphy, a security researcher; llkka Mattila of National Cyber Security Center of Finland and Fedor Indutny from Moscow.

Can you imagine if the server is virtualized and good number of virtual servers were existing on it?

Amazon Smartphone to release in September 2014

Amazon, known as America’s number one online retailer is all set to enter Smartphone business segment, by launching its own gadget in September 2014. Amazon is planning to come up with a Smartphone which uses retina-tracking technology to make some objects in the phone appear as 3-Dimensional, without the need of special glasses.


Disclosing the same through ‘The WallStreet Journal’ last week, Amazon has given a briefing in the article and gave a hint that it will go after Apple and Samsung from now on.

So, will the online shopping website stop selling Apple and other smartphone gadgets, in order to promote its gadget as a true leader? Well, nothing can be concluded now itself on this note.


Amazon is already competing with companies like Google, Microsoft, Apple and is offering web services like IP TV, Tablets and such till date and now we will see its entry into smart phone later this year.


Will its entry make any major impact on present Smartphone market? It won’t as smart phone market already seems to be saturated and another entry into this field will not make much of a difference, unless, low cost, reliable mobiles filled with exuberant and unrivalled apps are offered on Amazon Smart Phone platform.
