Edge Storage

> Edge storage – Allows cameras, encoders to record directly to

storage device such as an SD card – Sometimes referred to as local storage or on

board recording

> Other recording methods include – DVR – NAS – SAN

What do we mean by Edge Storage?

> ‘Not a security solution’

> Too expensive

> We don’t need it – there’s no driver and it doesn’t integrate

> It’s not a viable technology today – but it might be in a few years

Why hasn’t Edge Storage taken off before?

Not a security solution

> Why did we bother making screens HD and flat?

> PCs were never going to be commonplace

> Digital technology has made video surveillance more powerful – yet easier to use

> How easy was it to record to VHS?

> Even cameras are becoming sleek and modern

As technology evolves, so does video surveillance

Too expensive

“The 32GB SD card that costs 12x its weight in gold”

> SanDisk releases world's first 32GB micro SD card

> 11x15x1mm card consists of eight 4GB memory chips stacked vertically on top of one another

> Card weighs only 0.5g – Retail price of £145 ($230)

– Worth roughly 12 times its weight in gold**

Inhibitive price – even in 2010

Presentation Notes

Look at what the price used to be – I found a 32GB card today by a major manufacturer, Class 4 for £18.75 in the UK – that’s $0.93 per GB Standard 32GB SD memory cards, with write speeds of at least 10MB per second, can now be found for around US$20

Presentation Notes

Example small system 2GB and 8GB storage for comparison only 98% reduction in price of on-board storage

There’s no driver and no integration

> Power consumption of micro SD cards varies by manufacturer – No moving parts – 11*15*1mm, <0.5g – Range of 66-330 mW (20-100 mA at a supply voltage of 3.3 V)

> Low-energy 4-port 160GB DVR – Moving disc – 40*200*140mm – 1.2kg – 40W external power supply (additional 10W per channel used)

Not a viable technology today

How much can be stored on a 32GB SD card?

Presenter

Presentation Notes

Amount of storage depends on the avarage bitrate of the video. The bitrate depends on stream settings and scenario. The example in slide is based on continious recording H.264, 30 fps, medium compression office environment. If event-driven recording is used (and/or lower frame rate), the retention time will of course increase.

Presentation Notes

Amount of storage depends on the avarage bitrate of the video. The bitrate depends on stream settings and scenario. The example in slide is based on continious recording H.264, 30 fps, medium compression office environment. If event-driven recording is used (and/or lower frame rate), the retention time will of course increase. Most software applications see people retrieving data about 50% of the time and storing data 50% of the time NVR storage typically records 100% of the time, with only 1% playback Standard spec servers max out at relatively low camera count with high quality (HD) full framerate recording (processor hungry)

What is the expected lifetime of a 32 GB card?

Presenter

Presentation Notes

The SD card may only be rewritten a fixed number of times. How many times may vary from 1000-5000 times. The lifetime depends on how often the whole card is rewritten. The example in slide is based on continious recording H.264, 30 fps, medium compression and apprx 2000 total rewrites. Note: This is no guarantee as quality on the card may vary.

> Use brand names

> Size should be at least 16GB preferably 32GB

> Use Class 4 or more. Class states read/write speed, not quality

Which cards should be used?

> Edge storage, controlled by the camera/encoder can not only work standalone but also complement VMS solutions

> Recording redundancy

> HQ video in low bandwidth environment

> Remote site storage

Overcome challenges

VMS

Central storage

Presenter

Presentation Notes

Edge Storage is all about enabling the camera to record video to a storage device. Edge Storage recordings are controlled and owned by the cameras. The camera has its own recording database. The VMS can list and stream recordings from the camera and does not access the video files directly. Edge Storage is a complement to VMS recording , not a replacement. Edge Storage enables various cost-efficient recording solutions such as Possibile solutions where Edge Storage may reduce cost and add value Recording Redundancy Possibility to get High Quality video clips in low bandwidth envirnoment Low cost remote site recording (a.k.a. 2-tier storage) All four solutions may be solved by adding additional NVR or VMS Servers, but… Local Storage is the most cost efficient way to implement customer request and requirements Use standard off-the-shelf storage devices No PC, servers, NVR are required The listed areas can be solved using additional NVR, DVR or VMS. Note: Edge Storage may not be suitable for every type installation and recording solution…

> Safeguard uninterrupted recording for mission critical installations

– Retrieve “missing” video from camera

System redundancy for mission critical installations

GAP

Video

Presenter

Presentation Notes

As long as the camera has power, other system components such as switches, routers, servers may fail. The VMS can easily retrieve missing video from the camera and merge these clips back into the system.

> Monitor low bandwidth/quality video

> Request high quality video clip upon incident

High-quality video in low bandwidth environments

Low bandwidth/Quality

Presenter

Presentation Notes

In some environment the bandwidth may be limited for continuous HQ video streaming. One example being City Surveillance. These solutions may monitor and record a low bandwidth video (low fps, low resolution or high compression). The cameras will continuously recording HQ video with Edge Storage. This enables system to retrieve HQ video clips upon incidents.

> Low-cost remote site recording solution

> Transfer all or selected clips to central VMS

Remote site storage

Presenter

Presentation Notes

Edge Storage for remote sites may be used in various configurations and for different purposes. The camera is added to the VMS but configure to keep recordings on the Edge Storage. The VMS may retrieve all video or just clips to be merged into the VMS recording database.

> SDHC cards currently maxxed at 32GB

– SDXC cards on the horizon (2TB, 300MB/sec)

> Further integration with other video storage and management (VMS, NAS)

> Increased processor capability at the edge

What next for Edge Storage?

Edge Technology The future of analytics

> Every 18 months you get twice as many transistors/performance for the same amount of money

> Moore's law from 1965 is still valid!

Technology evolution

“No exponential is forever… but we can delay ‘forever’.”

Presenter

Presentation Notes

Moore’s law was described by Mr Gordon Moore who was co-founder of Intel. He described in 1965 and said that every 18 months the performance will double for the same amount of money in a integrated circuit. This gives an exponential increase of performance over time. The base for this evolution the size reduction of transistors used in the Integrated circuits. At time Mr Moore’s defined the law people said that this is maybe true �for some time but nothing is Exponential forever. I agree that nothing is exponential forever but now 45 years has gone and it is still valid and it is not expected to stop in at least the coming 10 years.

> 1996: 1 fps in 0.1 Mpix

> 2010: 30 FPS in 2 Mpix

> This gives 600 times improvement

> 14 years from 1996 to 2010

> Moore’s law means – 2x2x2x2x2x2x2x2x2: >9 times

> Total = about 600 times

Let’s validate Moore’s Law

Yes, Moore’s Law is valid!

Presenter

Presentation Notes

Martin: Let´s see, Network cameras is 14 years old. Divided with 1.5 gives 9.5 times Multiply 2 9.5 times gives 600times better preformance In 1996 we had 1fps in 0.1MP Today we have 30fps in 2MP That is 30 repektive 20 times Yes, Moore’s law works!

Network camera performance evolution

Do we want 600 times higher resolution/framerates, 300 MP/120 fps ?

Presenter

Presentation Notes

The first Network Camera only had 1% off Analog Camera’s capture capabilitywhen it was introduced 1996, it was it’s Network capability that was the driver. But as Network Cameras follows Moores law the evolution went fast and about 2002 it reached the same capability as the analog one and today it is much more. So what will happen next, do we need 600 times higher Image Capturing, 300 Mp and 120 fps ? Probably not even if we want�much more than today. The conclusion is that it will be, already are, a lot of performace �to manage other things in the camera.
