What is involved with setting up BAM ver 2.0?

Looking to setup BAM ver.2 and I need to know what all is involved. Price, hardware components, how it works, what version of firmware does it work with. I have both 900 and 5.8 working currently without bam, what if I don’t use it, what are the ways someone could disrupt my network?

Can someone also point me to some very detailed documentation on BAM.

Thanks for any and all replys.

Stay safe and Be well!!!
