Central Security Group is located in Tulsa, Oklahoma. They claim "30 Years of Security, Safety and Peace of Mind" on their website.
Central Security Alarm Monitoring serves Florida, Georgia, Alabama, parts of California, Indiana, Louisiana, Mississippi, Texas, Arkansas, Kansas, Missouri and Arizona
Central Security Group Alarms does not give pricing information on the phone, or even information about its services, unless it is absolutely certain you will buy one. Their phone manners are something to be desired.
The reviews are as bad as the phone manners. There are reports that Central Security Group Alarm Monitoring will tell you that their repairs are free if they are not your fault. One customer had her house struck by lightning and the repair wasn't covered. They will not cancel your service when requested. The only people who seem to be happy with Central Security Group Alarms are the ones who read their contracts carefully.
