I've recently started with BE internet and after humongous problems with BT Internet and previously 7 years flawless access with NTL(it went to pot soon after they re-branded to Virgin). BE runs much faster than did BT & I can download or upload whatever I want at good speeds, very very generous bandwidths.
BE are a good ISP, their tech support, took about a day and a half via email (it wasn't an urgent problem) and they replied and had it sorted within hours later.
So, not quite perfect, but very good.
Don't be so harsh on BE.
I've never seen the point in that home security/monitoring solution either, there's plenty of other methods and software that do a great job.
My 2 $$'s.
