I bought a New home in 2008 that had a burglar system installed by AMS (previously CES). We had issues with their initial products and finally spent another $9k with them to upgrade their system in 2016. Then in app. 15 months their newly installed system stops working. The problem is the systems they install have issues. They then charge a service fee to fix their faulty system....who does that - $99 an hour to fix their faulty piece of equipment?? The DVR was defective (warranty), they shipped it back for repair, but they charged us the 3+ hours they spent diagnosing and trying to fix the issue - they couldn't fix it but they still charged us....... Folks our house has over $20k of security from AMS / CES and these guys still nickle and dime me even when the issue was their own. Buyer beware!
