CCTV/IP Advantages over Traditional Systems • Improved system scalability • Adding cameras is similar to adding another computer to your network – no additional TMC equipment • Video switching is handled at the packet level by the network – no more matrix switch expansion modules • Network convergence - CCTV can integrate with other Ethernet/IP field network devices (i.e. traffic controllers) over the same backbone – no additional communications infrastructure required • Reliability – IP networks support alternate routing and redundant network links

Copyright © 2006 Askcom. All rights reserved.

CCTV/IP Advantages over Traditional Systems • Open standards support • Encoding/Decoding formats are standardized – open source software decoders exist, hardware decoder interoperability improving • Ethernet/IP network transport • Compatible with NTCIP • Software based control eliminates dedicated and proprietary • hardware – switch matrix, multiplexers, sequencers

CCTVoIP Summary

•  CCTV security industry is migrating to IP •  Traditional analog systems may be more cost effective for • smaller deployments •  CCTVoIP may be more cost effective for: • 

Systems with large number of field cameras

•  Systems with existing Ethernet/IP infrastructure – leverage existing • hardware •  Multiple distributed control points or centers
