How to calculate network performance for video surveillance in an organization (educational institution)?

Question

CCTV

What factors and criteria should be taken into account when calculating performance? Thank you.

Answer 1

To calculate network performance, you first need to sit down and draw up a block diagram of where and how the traffic from the cameras will go.
By the way, what network are you asking about? If we exclude exotic and proprietary protocols, cameras can be analog, DVB or IP. Based on this, there will be a network. So what is yours? Better with a diagram, anyway, you will need it later.

Answer 2

based on the virtual load of virtual cameras from the virtual manufacturer. ask and I will definitely tell you something else for
sure you have very good motives for asking the same question twice What problems arise when choosing video surveillance systems, especially the implementation of such systems?

Answer 3

If this is a topic for a diploma or a term paper, then by the time it is written, you should have enough knowledge to calculate such things yourself.
All known factors and criteria must be taken into account.
But first you need to decide what kind of video surveillance will be - on analog cameras or digital ones.

Answer 4

Do you mean will your network hardware have enough performance to install a certain number of cameras of a certain resolution so as not to affect the operation of the local network as a whole?
Firstly, where will your cameras send the image - a computer on a local network or, for example, some kind of cloud (to calculate whether the outgoing Internet channel is enough for you in the second case), and secondly, look at the peak load on network equipment (this is to understand how many percent of capacity is available to you), thirdly, look at the characteristics of the cameras to understand what percentage of the channel they will "eat off" from the network infrastructure. Based on this, it will already be possible to draw a conclusion about how many cameras we can put as much as possible. If this number of maximum possible installed cameras is much more than the required number, then you will not greatly affect performance, if not, then it makes sense to reduce the number or upgrade equipment. At least that's how I see your question.

Answer 5

Once again: an organization-level video surveillance system needs to be designed. There are a lot of factors. And in each case they are different.
