IP Cameras

• Connect directly to Ethernet network
• Wide variety of models available for all
  applications

Fixed
Mini-Dome
Pan/Tilt/Zoom
Bullet
8

• Most cameras have high resolution available
• 640 X 480 (4 CIF)
• 720 X 480
• MegaPixel IP Cameras are available
• Up to 5 MegaPixels

9
IP cameras with megapixel resolution allow for
highly effective digital zoom capability and
virtual pan and tilt functionality

• Power Over Ethernet (IEEE 802.3af)

• Less cabling
• Can be added using injectors (mid-spans)
• Use existing Voice over IP switches

11

• Various video compression methods are available
• Motion JPEG
• MPEG4
• H.264
• Wavelet
• Most cameras only have one or two types of
  compression available

13

• The camera can be used as connection device for
  other types of data
• Alarm Inputs
• Alarm Outputs
• Audio (Bi-Directional)
• RS-232

14

• Many models have card slots available for
  wireless Ethernet adaptors or local storage
• Many options are available for wireless
  connection to cameras

15

• Most models have built-in motion detection
• Some have built-in video analytics
• Intelligent motion detection
• Abandoned object

16
NVR

• Software Solution
• Installed on a non-proprietary server
• Advantages
• Customers can source their own servers,
  workstations, and storage devices
• Can be less expensive in cases where there are a
  large number of cameras being recorded at a low
  frame rate
• Virtually all IP cameras are supported
• Virtual matrix switch software is available

17

• Disadvantages of software NVR
• Can be more difficult to install and service
• Higher total cost in most cases
• Limited integration with access control
• Customers can buy their own servers and storage

18

• NVR on proprietary hardware
• Software is pre-installed on hardware provided by
  the CCTV manufacturer
• Internal or external storage is also usually
  provided by the CCTV manufacturer
• Advantages
• Easy to design the system
• Easy to install and service
• Many of these types of NVRs can be integrated
  with access control systems
• User interface may be similar or identical to
  DVRs
• Well developed suite of features inherited from
  DVR technology

19

• Disadvantages of proprietary NVR
• Usually support a very limited variety of cameras
• Customers that desire IP surveillance systems may
  not want to be locked into proprietary server and
  storage hardware

20
IP Video Challenges

• Hardware Cost
• 300 to 500 more per camera
• Requires a higher level of skill and training to
  install
• Introduces a different group of competitors
• Internet Resellers
• Network VARs

21
Where to use IP Video
Existing IP network infrastructure can be utilized

• Gigabit Ethernet Backbone
• Schools, office buildings, etc.

22
Large facilities or campus environments

• Server pulls video over network backbone
• Long distance home-run cabling is not required.

23
Cameras are widely distributed

• Locations are connected via a WAN
• Recording is done at a central location

24
More Applications

• Customer needs high resolution images
• Most surveillance grade IP cameras can provide
  higher resolution images than DVR
• MegaPixel cameras can provide very high quality
  images
• Remember that they will require at least 20 times
  more storage space than a standard camera
• Customers with the future in mind
• Customers with a strong IT department
