Changing Trends in CCTV

Traditional CCTV               Evolving CCTV System
  System                        Analog and digital
 Analog cameras and             cameras utilizing
  VCRs                           network storage
 Human observer and             capability
  “forensics” – what            Real time software-
  happened?                      based
 Video image archives           analysis/response
  on tape                       Video data mining
 Separate applications         Connected functions
  using separate cabling         over common cabling


                           6
Growing Opportunity:
Analog and IP CCTV Cameras




     2008     2009    2010       2011   2012       2013




   By 2013, 13.6M cameras will use a UTP channel      Frost and Sullivan, 2007


                             7
Convergence Drivers
 Remote accessibility – Improved asset
  management
 Ability to upgrade to future
  applications
 Simplifies Troubleshooting
 Lower TCO (Total Cost of Ownership)
  by leveraging same network for all
  building automation systems
 Supports high-definition (i.e. megapixel)
                        8
Structured Cabling Benefits

 –   Reliability
 –   Standards’ based
 –   PoE powering of devices
 –   Investment protection for future
     migration: Compatibility with
     other external systems (beyond
     video surveillance)


                               9
Structured Cabling
Additional Benefits of IP
– Reduce staff &
  labor on
  monitoring

  locations

                        10
Challenges with Structured
Cabling

           New Rules: Standards’
            based
           Ethernet Cable
           Network Stability
           Bandwidth

Standards vs. Codes




                 NEC                      ANSI/TIA/EIA
                 80+ Years                18+ Years
                 Codes                     Standards
   Purpose:      Safety                     Performance
   Compliance:   Force of law               Voluntary
   Sanctions:    Fines, halt in project     Shorter useful life cycle


                                12

                                                        12
Codes
 NEC (Nat’l Electric Code)
  – Produced by National Fire Protection
    Association (NFPA)
  – Revised every 3 years
 NESC (Nat’l Electrical Safety Code)
  – Produced by IEEE
  – Revised every 5 years
 CSA (Canadian Standards Assoc.)
  – Produced by National Fire Protection
    Association (NFPA)
  – Revised every 3 years


                         13
NEC 2002/2005: Abandoned
Cable
 Abandoned Cable definition:
  - “…Installed communications cable that is
    not terminated at both ends at a connector
    or other equipment and not identified „For
    Future Use‟ with a tag”
 Who’s responsible?
  – Building owners
  – Cabling contractors
  –

                          14
NEC 2002/2005: Abandoned
Cable
Outcome
  – Property will not meet code
  – Jeopardizes fire insurance
  – Failure in obtaining a building occupancy
    permit.




                       15
New Rules: Standards’ based
TIA-568-C
 Recommended cabling and connectivity
  components that will support a wide variety of
  existing and future services
 Centralized “Star-wired” topology
 Defines performance levels for Category 5e, 6
  and fiber channels
 100-meter channel distance for twisted pair
   Backwards compatible

   Smallest diameter

   Variety of constructions
   Associated costs



                      23
Benefits of UTP/Fiber
Cabling vs. Coax
  Category 5e and Category 6 (vs. coax):
    UTP has a much smaller diameter
     (RG59 = .280”, Category 5e =.165”)
    Lower cost in materials and labor
    Balanced cable vs. unbalanced coax cable
     (eliminates ground loop, less susceptible to EMI/RFI)
    Power over Ethernet (PoE)
  Fiber Optic Cable
    Secure cable
    EMI/RFI resistant
    Long Haul

   PVC C5e $95 / 1,000 ft                PVC RG-59 $156 / 1,000 ft
 Conduit size                          Conduit size
 Cost of transceivers                  Cost of:

  PoE (Power over Ethernet)
 PoE (IEEE 802.3af)
  – 2-pair
  – 13 Watts
 PoE Plus (IEEE 802.3at)
  – 3rd Q 2008 under “comment resolution”
  – Expected to ratify 1Q 2009
  – Problems with 30 W – now at 24 W over
    2-pair
  – Rise in heat within cable (+10º) will create
    insertion loss


                             30
 PoE Plus+ Potential

 Possible security devices powered

Summary: Planning for Total IP
Convergence
  Converging applications will
   require a more sophisticated
   network system (UTP and
   fiber) and an open
   standards/centralized platform
  Pre-planning with both I.T. and
   a security integrator
  Ethernet applications (IP)
   requires quality cable and
   connectivity!
