1 Optimizing the In-Car Digital Video Process: From Cuffs to Court LEIM 2009 May 20, 2009

2 Your Presenters Chris Lee Technology Operations Manager Greg Peratt National Director, Digital Video

3 An Introduction to Lewisville, TX 94,000 people Located 25 miles northwest of here Encompasses 42 square miles 3

4 Lewisville PD Overview 138 Police and 63 civilian positions 50 patrol vehicles State-of-the-art jail facility capable of holding 54 inmates. Chief Russell Kerbow 4

5 Analog In-Car Video Deployment In 2006, Lewisville PD first deployed analog video cameras in patrol cars Problems started piling up over time Tape wears out after multiple recordings Time-consuming to find evidence Physical storage costs 5

6 Made the Switch to Digital Chief Kerbow sought alternatives to analog Priorities for selecting new solution included: Ease of use for officers High storage capacity Evidence is secure and auditable Selected Panasonic Arbitrator system 6

7 Managing Officer Concerns During deployment, officers concerned about constant monitoring Decided to limit the audio recording Officers quickly saw how they re protected from fraudulent claims of: Harassment Abuse Profiling

8 Improvements with Digital Recording starts with trigger event Speedometer reading Lights flipped on DVR functionality preserves video 2 minutes before trigger, capturing the offense High-capacity P2 card stores dozens of hours of video Easy control through mounted touchscreen laptops

9 Automatic Evidence Transfer When car pulls into station, video is uploaded to server over WiFi connection

10 Evidence Easily Stored and Located Metadata tags for each video Searchable by categories such as incident, car number, officer name, date/time Permissions settings and access record Personalized settings on how long to store videos

11 Protecting the Chain of Evidence Video cannot be tampered with Every interaction is documented Videos are backed up in case of disaster

12 Synching up with Court System Lewisville Courthouse shares network with Police Department Prosecutors and court administrators can access videos instantly Prevents unnecessary challenges to traffic tickets

13 Results from Deployment More convictions prosecutors love it Lets cops do their jobs No need to think about the camera Saving manpower and budget Officers don t need to take overtime to fight ticket challenges in court

14 Advice for Agencies Considering Digital Video Create Digital Video Policy and Procedures before deploying technology Have a clear scope of the amount of time you need to retain data Keep necessary officer interactions with in-car hardware to a minimum Be sure to have an adequate backup solution in place to handle the volume of data

16 What does the Future Hold for Digital Video?

17 Combined Technologies Fixed Video ALPR Streaming Video

18 The Goal Present an accurate depiction of an event from Cuffs to Court

19 The Next Leap in Digital Video Offers Quality and Size (Bit-rate) Much better compression efficiency than previous compression schemes The improved efficiency translates into three main benefits: Higher video quality at a given bit-rate: reduction in artifacts such as blockiness, color bands etc. Higher resolution: as the video world transitions to High Definition, a mechanism is needed to deliver it. Lower storage requirements: lower storage requirements will allow for large amounts of content to be delivered on a single disc.

20 The Difference is Clear MPEG 2 H.264 For a given bit-rate, the level of video quality or resolution is greatly enhanced with H.264

21 Wearable Camera Concept What is Wearable Attaches to the officer (no need to hold) Able to record video / still images/ audio data without any officer intervention Wearable Camera Features 1. Image Stabilization Prevents the undesirable shake and vibration from walking / running 2. Super Wide Angle 180 Degree Capturing panorama image (180 deg) by Super Wide Angle Mirror Wearable Camera (Loop type)

22 Image Stabilization Benefits Prevents shake and vibration when walking / running Easy to track the target objects (ex. person, license plate) Technical Features Robust motion estimation using sensors (eg, gyro) and image processing Original Stabilized Image
