False alarm

I have installed a fire alarm in my house but it triggers an alarm even after it detects a small quantity of smoke. It has really become a burden for us now. What can we do to avoid false alarms? I have read that installing a cctv can be a solution to reduce false alarms (http://www.fire-monitoring.com/using-remote-cctv-video-monitoring-to-reduce-false-alarms-and-false-dispatches/). Can this be counted as a solution to my problems? Can someone recommend any other alternative solutions?
