Sure. ADT quoted me around $500 for equipment, but tag on a $48/mth monitoring service for 3 yrs. Equipment used is PowerMax, which I think originates from Israel but now quite popular in US and Europe. So cost over 3 years is over $2K.
My experience with Cisco is less than pleasant. First, the sales person didn't turn up for first appointment. Then, he gave a quote less than $2k. Then, after a few weeks he's no longer working there. Then the new chaps that came said the first quote should be disregarded as the system proposed was completely not suitable or appropriate, and indicated a quote of $10k!!!!!! (no monitoring service). Cisco uses GE equipment, and doesn't force you to sign up for monitoring service.
Any other feedback on security systems would be much appreciated.
