Why IP Cameras

Some Observations
• Scalability is superior in IP based systems, where one camera at a time can be added
• Flexibility is greater in IP based system, when moving a camera means only moving a network drop if PoE is used
• The image quality of network cameras is superior to analog
• Megapixel cameras are beginning to be specified, which can only be addressed by network cameras
• IP infrastructure is often already in place, and can be used by the network video system
• Analog Coax cabling much harder to troubleshoot than IP design costs typically included at no additional cost
• IP system can be remotely serviced, e.g. adjusted / diagnosed over the network
• Brand name PC servers used in IP systems often have superior warranty and service plans compared to DVRs
• IT equipment likely to drop faster in price than analog
Conclusion
• IP based systems of 40 cameras have a lower total cost of ownership than analog based systems. Based on a typical deployment scenario; the cost to acquire, install, and operate an IP based system is 3.4% lower than an Analog based solution.
• 32 cameras is the break even point for IP systems versus analog. Based on common scenarios for costs scenarios, beyond 32 cameras the IP based system is lower cost, and between 16 and 32 the cost is quite similar even though slightly lower for analog systems.
• If IP infrastructure is installed the IP system is always lower cost. For any size system IP system will always be lower cost if IP infrastructure by means of cabling already exists.
• Many non-quantifiable advantages for IP systems. Improved images quality, better maintenance and service, increase flexibility, easier to trouble shooting, are just some of the advantages that exist but were not quantified. Additionally, IT equipment is expected to fall in price faster than analog CCTV equipment, making the comparison even more favorable in the future.
