We recently used Safe Systems Inc. and we were not too crazy about it. We moved in the middle of our contract and there were lots of issues with that. We were told one thing, but another happened. We were told we could use the original contract, but it caused problems with people buying our old house. We ended up having to sign a new contract. Also, there were times where the alarm went off and we did not get any follow up on it. We were not too impressed.
