How many 2 Megapixel camera can be on 1 point to point link using MST200?

I want to create a point to point and point to multipoint solution the distance is diffrence from 30 to 100 meters so I want to know how many cam can be based on 1 link point to point or point to multi-point based on   MSR2K and 2x MST200

What channel bandwidth between the APs? What is the FPS and compression codec of each camera?

So figure each camera can use anywhere from 4-7Mbps depending on framerate. So from there, you have to identify what channel bandwidth you will be running.

 

PtP: HT20 would be around 6-8 camera feeds, HT40 would be around 10-14 camera feeds.

PtMP: HT20 would be around 4-6 camera feeds, HT40 would be around 8-12 camera feeds.

 

All of that is ballpark because there are just too many variable to contend with, so until you know and have measured the bandwidth of the actual camera, that should be a reasonable assumption. Note that if you are not doing any kind of buffering on the camera, you will likely have some level of jitter with that kind of video load over a PtP link.

Thank you for the helpfull answer I actaully planning to use HT20 to avoid interference on HT40
