Axis Design Tool - Version 1 v Version 2 -Storage Difference

[ciskokid 0]

Hello to Everyone

 

Im anewbie to CCTV and storage. Im a networking guy and Im now in a position where Im responsible for reviewing some technical details on storage requirements.

 

Appreciate any advice anyone can give.

 

I hope someone can give me some advice on something that I am finding very confusing.

 

Im in the position of representing an investor and our ELV sub contractor is offering me a significant amount of P3343 12MM network cameras.

 

I'm based in the UAE and we require the following parameters for viewing and recording-

 

CIF (480x360 on the Axis design tool)

H.264

12FPS

24HR Viewing

24HR Recording

Stairway Profile (Only specific to Axis)

 

 

I am only concerned with working out the daily recording rate. They have told me to use the Axis design tool 1 even though its discontinued and when I input the parameters I get a daily recording rate of 3.2GB per day per camera that is if you use the data shown above,

 

Design Tool 1

If however I use design Tool V2 which Axis recommend I get vastly different storage results-

 

http://www.axis.com/products/video/design_tool/v2/http://www.axis.com/products/video/design_tool/v2/

 

With the same parameters although you are choosing CIF instead of 480x360 I get a figure of 5.23GB per day.

 

So nearly 2GB per day between the two tools which is a lot when you are in the realms of 500+ cameras.

 

I also have a requirement for x15 cameras (P3344 12mm) at the following Profile

 

4CIF (640x480 on the Axis design tool)

H.264

24FPS

24HR Viewing

24HR Recording

Station Profile (Only specific to Axis)

 

So design Tool 1 shows a daily rate of 21.2GB per camera and the same parameters on Design Tool 2 shows 209GB per day which again is nearly x10 times difference between the two tools.

 

I find it quite astonishing that the two Axis tools can be so different and I'm hoping someone can tell me what tool I should be using and what Ver2 is doing to come up with the extra requirements for storage.

 

Many Thanks

I have obtained the following results:

 

1. /////////CIF (480x360 on the Axis design tool)

H.264

12FPS

Compression - 50

24HR Recording

Stairway Profile (Only specific to Axis)

 

Axis Design Tool 1 (320*240) - 80kBit/s 843.7MB/day

Axis Design Tool 1 (480*360) - 181kBit/s 1.8 GB/day

Axis Design Tool 2 - (CIF=352*288) - 40.9kBit/s 0.44 GB/day

 

The Axis Design tool 2 gives result in 2.5 times less than the Axis Design Tool 1.

It seems like an error in the Axis Design Tool 2:

In the Axis Design Tool 2, 4CIF produces in 10 times more traffic (427 KBit/s) than CIF (40.9KBit/s), but the 4CIF has only in 4 times more pixels.

In the Axis Design Tool 1, 640*480 produces in 4 times more traffic (321 KBit/s) than 320*240 (80KBit/s), that is correct.

 

 

2. ////4CIF (640x480 on the Axis design tool)

H.264

24FPS

Compression - 50

24HR Recording

Station Profile (Only specific to Axis)

 

Axis Design Tool 1 (640*480) - 1268kBit/s 13 GB/day

Axis Design Tool 1 (800*500) - 1650kBit/s 16.9 GB/day

Axis Design Tool 2 - (4CIF=704*576) - 1.71MBit/s 18.5 GB/day

 

Approx the same result in the second case.

Hi Stanislav

 

I think I may have confused the post.

 

If I simply compare this profile between both design tools:-

 

CIF (480x360 on the Axis design tool) as I have no option for CIF

H.264

12FPS

24HR Viewing

24HR Recording – 10% Compression (minimum)

Stairway Profile (Only specific to Axis)

 

I get 1.4GB per day on Design Tool 1.

 

If I use design tool 2 and I have no option to select 480*360 and so I use this profile

 

CIF

H.264

12FPS

24HR Viewing

24HR Recording – 10% Compression (minimum)

Stairway Profile (Only specific to Axis)

 

I get 5.23GB per day on Design Tool 2.

 

Is it me or is there a bug on the Version 2 design tool as its nearly 4 times more storage on version 2.

 

Thanks

Hi, Jimmy

I get 1.4GB per day on Design Tool 1.

I get 1.8GB (Compression=50). May be you just used other compression ratio.

 

If I use design tool 2 and I have no option to select 480*360 and so I use this profile

CIF

I understand that the Axis Design Tool 2 doesn't allow to specify pixels directly.

But the CIF is 384*288=110592 pixels is not equals to 480*360=172800 pixels. The 480*360 image has in 1.56 times more pixels therefore it must have in 1.56 more file size (in bytes).

Is it me or is there a bug on the Version 2 design tool as its nearly 4 times more storage on version 2.

I get 0.44GB (Compression=50). May be you used other compression ratio and mistaken with number of days.

 

 

This is the same as 0.44*1.56=0.69GB for 480*360. It is in 2.5 times less than in Axis Design Tool 1 (1.8GB). It seems like an error in Axis Design Tool 2.
