Multi-camera video surveillance software for the Mac
System Requirements Calculator
Set the parameters of your planned system below, and a list of suitable Mac models will be shown along with estimated maximum numbers of cameras of the specified type.
The results are only approximate as there are many variables to take into account, but the suggestions are reasonably accurate in most cases. If in doubt, use a faster Mac and more storage than suggested.
Note that the performance is highly dependent on codec, resolution and frame rate, so if you have a mix of different cameras, performance can be difficult to predict.
Please help us collect data to improve the accuracy of this tool by running our Video Codec Test utility on your Mac.
