1 New Technologies that Resolve Common Challenges Facing IP Surveillance By: David Heath Axis Communications

2 Agenda Difficult lighting conditions Low Light/No light Back Lighting High Band-Width requirements of IP Surveillance Video usability

3 Challenge: Difficult Lighting Let s begin with a word: Photography From the Greek words photos (light) and graphos (drawing) Light - an essential part of creating pictures and images Without Light. no image!

4 What is Light? Light, or visible light, is electromagnetic radiation of a wavelength that is visible to the human eye (about nm). Source:

5 Light concepts Understanding Light Direction Intensity Color temperature Wide dynamic range

6 Light Colour Temperature **Colour temp chart by Seesmart LED Inc.

7 Colour Temperature and Video To achieve the right color representation White Balancing Neutral (black/gray/white) colors in the scene should stay neutral in the resulting image regardless of the illumination

8 Difficult Lighting Cont. What if the area being monitored has no light? 0 Lux

9 Add light

10 The LED Innovation Light Emitting Diode Created by Oleg Vladimirovich Losev in 1927 First viable use in electrical components in 1962 Now LEDs are widely used in everything such as TVs, Street Lighting, and Camera illumination. Source:

11 LED lighting = Lower TCO Pros: Significantly longer life span up to 50,000 hours 53% energy savings over HPS technology Minimal maintenance costs May have a smaller footprint than HPS Cons: Initial cost to purchase is much higher

12 LED Lighting: upgrade from High Pressure Sodium Lighting City of Austin, TX Parking Structure - Before

13 LED Lighting: upgrade from High Pressure Sodium Lighting City of Austin, TX Parking Structure - After

14 LED Lighting: upgrade from High Pressure Sodium Lighting Crocina Tunnel, Arezzo, Italy

15 LED Lighting: upgrade from High Pressure Sodium Lighting 50%

16 LED Lighting: upgrade from High Pressure Sodium Lighting 75%

17 LED Lighting: upgrade from High Pressure Sodium Lighting Completion

18 IR LEDs Infrared Light Emitting Diode Created by Texas Instruments in 1961 CCTV illumination is typically between 850nm 940nm New High Efficiency IR LEDs available - 3 LEDs can achieve up to 100ft range - Adjustable angle and intensity

19 Camera location Adding light Match the angle of light to the angle of view provided by the camera > Ensure a distance of at least 1 m / 3 feet between camera and light source to avoid problems with insects

20 Adding IR Light No IR Day/Night Camera With IR Day/Night Camera

21 Visible light vs. IR White-light Infra-Red Advantages Visible deterrent Quick start (LED) Full color rendition Easy set up Covert or Semi Covert Longer distances No light pollution Disadvantages Light pollution Reduced distances Limited deterrent More difficult to set up

22 Innovation for Low Light? Lightfinder Technology

23 Lightfinder technology Lightfinder technology is a combination of many factors: Artpec4 Processor Latest generation light sensitive sensor Optimized high quality lens Elaborator Software

24 Image examples Perimeter surveillance with no street illumination during night time (10:40 p.m.) and approximately 0.1 lux.

25 Lightfinder Beach Video

26 WDR What is Wide Dynamic Range? The ratio of the brightest point of an image to the darkest point of the same image The goal is to get details in the whole image Specifically for strong backlight scenarios

27 Why WDR? Provide detailed images of complicated scenes with extreme illumination Improve visibility of details in blinding situations Improve color and overall image fidelity Fully exploit the dynamical details in a scene

28 The challenge varying light levels This image is underexposed, trying to capture the environment outside This image is overexposed, trying to capture the environment indoors

29 The challenge varying light levels Neither image manages to capture all the details outside and indoors

30 WDR Dynamic Capture By taking multiple images (3) at different exposure times Combines the images to achieve WDR

31 WDR continued

32 WDR with headlights

33 Challenge: Bandwidth High-Resolution Video + High Frame Rate + Complex Scenes = High Bandwidth Requirements

34 Bandwidth So how do we minimize the bandwidth without losing the resolution and frame rate?

35 The Edge Utilize the technology that s at the Edge to do more than just send video over the network

36 Use your brain The Processor is the brain of the Camera. The stronger and more efficient the processor the better the capabilities at the edge.

37 Processors Moore s Law: an axiom of microprocessor development usually holding that processing power doubles about every 18 months especially relative to cost or size Source:

38 Artpec-4 Processor 400 MHz Processor The key enabler to run Intelligent Video Analysis at the camera (Analytics) Manages the features of the camera such as remote focus and zoom, inputs and outputs, as well as the edge storage.

39 Artpec-4 Processor Improved image quality Better noise filtering Better sharpening Improved h.264 compression Support for four video ports Simultaneous h.264 and MJPEG streams in fps

40 Edge storage Edge storage, controlled by the camera/encoder will be an important complement to VMS solutions and provide new possibilities for efficient surveillance Recording redundancy HQ video in low bandwidth environment Remote site storage VMS Central storage

41 System redundancy for mission critical installations Video GAP

42 High-quality video in low bandwidth environments Low bandwidth/quality

43 Remote site storage

44 Local Storage

45 Analytics on the Edge to reduce bandwidth Running Analytics at the camera can significantly reduce the amount of bandwidth needed by only sending the important information the camera is gathering LPR People Counting Heat Mapping Cross Line Detection VMD

46 How to make recorded video more Only record on event useful? Use Analytics at the camera to cut down on the events and increase the accuracy of detecting an event Cross Line Detection Video Motion Detection Intrusion Detection Object left unattended Use Metadata

47 What is Metadata? Defined as: Data about Data

48 Metadata in IP Video Metadata as it relates to IP video is the data gathered from the image of the camera The direction, size, shape and the centre of Gravity of all moving objects in any given scene

49 Metadata

50 Metadata Applied in Enhanced Video Search

51 Find it, and find it much faster Define Start Tune area the the of search filter interest Significantly faster Less CPU consuming More reliable result 100%

52 Metadata makes it work! Metadata application must be installed Camera detects moving objects Recording stream Metadata comes in a separate stream A filter applied to match behavior

53 How does it make recorded video more useful? When utilized correctly, Metadata can detect what it deems is a security threat (through user definable attributes) and then only send the video of the specific threat, therefore minimizing the large amount of erroneous video that would be sent from a standard video system By only storing legitimate threats, you reduce bandwidth, lower storage needs and ultimately make the job of the observer/investigator easier by making the recorded video more useful and easier to find
