Removed post due to it being off topic I presume you wish help on wireless and posting in a specific ISP forum will bring no replies.
I will monitor incase this is a new way to start spamming the forum.
you could be a little more specific too, what do you want to know about them? how they work? where to get them? You will find that there are most likely alot of people who know about wireless cameras but if you are a little more specific with your request they may be more inclined to 'share the wealth' so to speak!
