Cabling for IP Camera vs. Analog Camera Solutions

You can see the large density of cables in an Analog Camera setup.Also due to the long distance between the DVR and the cameras boosters will be required and quality of video will be degraded

Only a single fibre or Cat - 6 cable needs to run from the top of the building to the bottom and no cabling mess required.Also the solution is flexible and easily scalable. Other services can also be operated through the same fibre cable.

IP vs Analog - What your system provider wont tell you

DVR	IP Cameras
1.End to interlace problems
·         Interlaced scan ·         Each image formed from two interlace fields ·         Blurriness from capturing moving objects, even when connected to a DVR	·         Progressive Scan ·         Entire image captured at one time ·         Crystal clear images even with a high degree of motion in the scene
2.Megapixel resolution
Stuck with NTSC/PAL resolution 0.4 Megapixel at 4CIF and 0.1 at CIF Limited image details	Many resolutions 1 Megapixel is 10x the resolution of CIF, 2 Megapixel is 20x! Different aspect ratios Digital PTZ
3.Integrated PTZ  and I/O control and storage
Analog cameras need separate Rs-485 cable and equipment(joystick) for control) Costly and cumbersome I/O only possible in DVR not on camera Recording not possible onboard camera.So if DVR is shut all lost.	PTZ control over the same network that transports the video PTZ commands sent over the IP network Integrated I/O can Trigger anything Can be triggered by anything
4.Audio
Only possible with separate audio lines to the DVR	Audio captured at the camera Synchronized with the video Can be integrated into the same video stream 2-way audio (Duplex, Half Duplex, Simplex)
5.Secure Communication
No encryption	Video encryption Authentication using encrypted certificates Authorization: to verify and approve the identity of the device Privacy watermarks
6.Flexible cost effective infrastructure
Expensive coax, proprietary fiber, wireless Distance affects image quality Adding power, I/O and audio further complicates this situation	·         IP = established, standardized, interoperable ·         Digital images = no quality reduction ·         Many streams transmitted over the same line ·         A single network wire = hundreds of simultaneous full frame rate video streams
7.True Digital Solution
With every conversion image quality is lost: Analog signal digitized in camera’s DSP Analog signal converted back to analog for transport over coax Signal once again digitized at the DVR for recording	Images digitized once Stay digital No unnecessary conversions No image degradation
8.POE
Not Available	Both network cameras with and without built-in support for PoE can take advantage of a UPS device Cost savings Reliability with centralized power backup Simple installation

WHY IP CAMERAS by livedarshan.com

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 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.
