IP Video System Design Tool

Last year we have made a test of CCTV design software . Our choice was a nice software called IP Video System Design Tool from JVSG

This software is really helpful and saved us a lot of time in our CCTV consulting work.

Last year we asked JVSG to make a special lite version of CCTV Lens calculator and bandwidth&storage tool for our website (now this offer unfortunately is over). More than 10 000 our visitors have downloaded and started to using this CCTV design software to design their CCTV systems more efficiently.

Description of IP Camera Calculator 3.0

If you need to calculate a required network traffic and storage space or lens focal length for your video surveillance system and you get tired of ugly online calculators, than this software tool is for you.

IP Camera Bandwidth & Disk Space Calculator lets you to calculate required network traffic and storage space for your network camera based video surveillance system.

Just select a resolution and compression level of your network IP camera (or your CCTV camera connected to DVR) , enter required FPS and number of cameras and the calculator will calculate required bandwidth.

If you specify for how long your video records have to be stored (1 day= 24 hours of recording) the tool will give you required HDD storage space.

This software tool is a great companion tool for video monitoring software.

Why this software is better in compare with online calculators? Our offline calculator is faster, has more convenient user interface and doesn’t need a internet connection.

Important! Frame size, calculated for specified resolution and compression is an estimated value. Real frame size value highly depends on image complexity, lens and CCD/CMOS quality.

New feature of the calculator is calculation of lens focal length. Just enter viewing angle and CCD/CMOS sensor size and get focal length.

How to calculate network bandwidth and required disk size properly

There are few important factors you should consider during “IP Video System Desing Tool” usage.


When you specify camera resolution and compression level you get just an estimated value of the Frame Size. In real life your camera’s frame size can be twice bigger or smaller.

The frame size depends on

To make a more precise calculations you have to make an experiment with your camera in its typical conditions and then put average result in the FrameSize column.

Practical Bandwidth

When you use 100 Mbps(Megabits per second) network it doesn’t mean the network allows 10 streams of 10 Mbps.

Real practical bandwidth value is always smaller.

Network Type Practical Bandwidth Value
Ethernet 10 Mbps ~ 7 Mbps
Ethernet 100 Mbps ~ 60 Mbps
Ethernet 1000 Mbps < 500 Mbps
WIFI 802.11b 6 Mpbs ~ 4-5 Mbps
WIFI 802.11g 54 Mbps ~ 13-24 Mbps

Also some manufacturers of IP cameras , like AXIS recomend to reserve 30% additional bandwidth for future expansion of your video surveillance system.
