A COMPARISON

Contents �  Capability �  Performance �  Cost �  Reliability �  Summary Table �  Additional Features �  Demo Video Link

Capability �  IP

Pros �  Allow the ability to zoom into recorded video �  Use one camera to cover a greater area without losing quality �  Can be reviewed remotely via PC or Smartphone �  Customisable video quality based on needs and storage capacity

Cons �  Only supports up to 100 metres transmission distance (CAT 6 cable)

�  HD-SDI

Pros �  Full HD live viewing and recording �  Recorded picture is 3 times larger than the size of Standard Definition cameras �  Supports up to 200 metres transmission distance without an extender (RG59 cable) �  Can be reviewed remotely via PC or Smartphone �  Customisable video quality based on needs and storage capacity

Cons �  Image quality can be affected by bad quality cabling

Performance �  IP

Pros �  Supports video resolution of 1080p (compressed) and higher Cons �  Cameras require optimum lighting to produce a high quality image �  Compression of video images requires larger amounts of data to be transmitted over a network

○  Compression rate and network bandwidth determines the quality of images produced �  Image lag is totally dependent on the bandwidth available on the network

�  HD-SDI Pros �  Supports true 1080p video resolution (uncompressed) �  Little to no image lag when viewing live and recorded footage

○  i.e. Allowing for more effective control of PTZ cameras

Cons �  Must use both high-end HD-SDI cameras and DVR to realise full performance benefits

Cost �  IP

Pros �  Can leverage existing network cabling (Cat 6) �  Fewer cameras required due to higher resolution images in a certain area Cons �  Using existing network cabling will dramatically affect bandwidth to other devices on the network �  Entirely new infrastructure and exclusive network required to realise full benefits �  Dedicated IT department required to monitor and maintain network network health for constant

24/7 CCTV recording

�  HD-SDI Pros �  Ability to leverage current coaxial cable infrastructure from existing CCTV system �  Plug an play installation with existing coaxial cable in place �  Significantly lower installation costs and faster time to market of a fully operational system �  Fewer cameras required to cover an area as HD picture is 3 times larger than a standard camera

Cons �  Larger storage requirements for capturing video footage on a 24/7 basis

Reliability �  IP

Pros �  Can utilise existing IT infrastructure for storage and backup Cons �  Recording can be compromised if there are interruptions to the IP network �  When problems are being faced it can be difficult to isolate a problem quickly

○  Multiple points of failure – i.e. router, hub, switch, cable, camera, NVR, network bandwidth

�  HD-SDI

Pros �  Recording immune to network IP network interruptions as it is a stand alone system �  Quicker turn around time in troubleshooting problems with the system

○  Limited to either DVR, cable, camera, power supply

Cons �  DVR unit must be placed in a well ventilated area for adequate cooling in order to maintain

longevity of the system
