In-Car Video Management:
Technology and Trends
Agenda
• Things to Consider– Analog vs. Digital
• What Makes a good Video Solution
• It’s All about Protection– Protecting: Officers, Evidence, Community
and Citizens
• Things to Come
Analog vs. Digital Technologies• Pre and Post event recording• Greater reliability – less moving parts• Higher capacity and more compact storage media• Better evidentiary value of the digital video file • Wireless transfer capability (easy and secure)• Ability to record additional metadata such as GPS,
speed, brake, etc• Better authentication and security capability• Significantly better search, storage, and security• Ease of sharing files
What Makes a Good Video Solution ?
• Quality and reliability of the video output • Quality and reliability of the Camera• Quality and reliability of the Recording• Quality and reliability of the Playback• Ability to safely store, transfer, search, copy,
archive, secure, and provide sustainable evidence in court – THE BACKEND!
• It’s a Business Driven Solution• System Support

Officer Safety
• Training Tool– Improve technique, SOPs
• Wider Angle– Allows officer to move out of traffic
and danger zones but still be “in frame”
• Zoom & Low-light Recording– Surveillance at safer distance– See what others can’t
• Protects from false claims that can derail careers and limit advancement
Protects the Evidence
• Clear & Detailed – Highest quality video
• Reliable– Rebuttable & Proven
Technology
• Secure & Tamper-proof• Efficient
– Smallest file size, best file management
Protects the Community• Risk Mitigation
– Protects from false claims that can cost millions of dollars and cause bad community relations
• Improved adherence to SOP• Invaluable investigative tool• Protected Video
– Try your case in court, NOT the court of public opinion
– Out-of-context video – Someone WILL record the event. You need a complete & accurate record
Protects the Citizens
• Provides Visual accountability
• Higher convictions rates takes dangerous criminals off the streets
Cameras that offer Wider Angle Lens Improves Officer Safety
Traffic Stop with Wide angle Lens
In 2006,247 Officers were
Killed here

Let’s look at that traffic stop again
This is the angle/coverage area of the average video
systems

The Goal is to eliminate or greatly reduce this

In an effort to improve officer safety, many
departments have adopted a “turn-out” SOP
The only issue is a normal camera angle WILL NOT capture the entire scene
A System with a Wide angle Offers Better
Coverage!
Here is an alternate form of a similar “Turn-out”
SOP
Here is what you get with a wide angle lens
And what you lose with standard systems

The Goal: Be able to present an accurate depiction of an event from
“cuffs to court”
The Next Big ThingH.264
• Quality and Size (Bit-rate)• H.264 clearly has a bright future, mostly because it offers
much better compression efficiency than previous compression schemes.
• The improved efficiency translates into three main benefits, or a combination of them:
• 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.
The Difference is Clear
For a given bit-rate, the level of video quality or resolution is greatly enhanced with H.264
MPEG 2 H.264
“Wearable Camera” Concept Overview
• 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)
Feature “Image Stabilization”• Benefits
– Prevents shake and vibration when walking / running
• Technical Features
– Robust motion estimation using sensors (eg, gyro) and image processing
Original Stabilized Image
Easy to track the target objects (ex. person, license plate)
