About 30-50% more, when not  recording by motion.

Could we have a similar table or estimator with VCA and LPR operation?

Hello,

may you also add in to this post information about disk array recording bandwidth limitation calculation. or it was made for 1 HDD in server? What will happen if customer will use mirroring etc. This should be like white paper which will help us a lot to work with our partners (SI, installers). Or better include this info in your DataSheet Smile

For instance in Bosch or Panasonic recording sollution you always may fined info regarding how many Mb/s you may record and how Mb/s you may stream to the Surviallance station.

Q-ty of remote connections are also sentiable in this case. Than more such info and easy to fined it than more comprehansive become SW)

Sorry for spamming, but you also should mention the coding format of camera (JPEG, H264) which you use in this calculation.

The figures above are NOT the absolute MAXIMUM - the server can do more.

Because it is not maximum, recording mpeg4 or h.264 wont be a problem.

Basically, theres enough processing power left to handle h.264.

Hope this helps.

For instance,

The DSA‑N2B40 provides a maximum bandwidth of
400 Mbps with a maximum of 256 concurrent iSCSI
connection

With such info you alwas may calculate according to the Video settings q-ty of cameras for archiving)

Romsat

I think that you must separate 2 different things : Storage and camera management.
you are talking about storage capacity, as Dario was talking about appication server performance. In addition with the iSCSI product (Storage server) you're talking about, you must add an application server with database wchich manage the cameras (for Bosch). It is the same for Digifort if you need high capacity (But without extra license charge ...)

To calculate the maximum storage capacity of your system, it depends on the product you want ie HDD, storage server and settings.. Because Storage size and performance depends on HDD quality, raid level used, storage server quality also (In Bosch, 400Mbps is the higher limit with enterprise HDD, don't put commercial grade to get this performance...).

Digifort is an opened plateform, hardware is free, so you can chose what performances you need for your customer. Not the case with expensive Bosch closed system.
