Anyone get an insurance discount for having a CCTV system?

Just curious for those of you with residential CCTV systems - have any of you gotten insurance discounts for having such a system and did you have to jump through any particular hurdles if you did to get it 'approved' by your insurance company (like an inspection or minimum requirements,etc)? Just curious.. I popped a note to my carrier (USAA) to see if they give any CCTV discounts -- I don't mind if they come and inspect after I get it all installed. Seems to me that a decent CCTV system ought to be similar to having an alarm system discount unless the thief steals your NVR/DVR that has the recordings on it..
