4.
5. Sometimes called Video Servers
Convert analog cameras to IP
Usually 1 or 4 camera inputs
Alarm Inputs and Outputs
PTZ Control for most brands
Audio Inputs Available
6.
7. Connect directly to Ethernet network
Wide variety of models available for all
applications
Fixed Bullet Mini-Dome Pan/Tilt/Zoom
8. Most cameras have high resolution available
◦ 640 X 480 (4 CIF)
◦ 720 X 480
MegaPixel IP Cameras are available
◦ Up to 5 MegaPixels
10. • 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
12.
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. 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. 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. 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. Locations are connected via a WAN
Recording is done at a central location
24. 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
