False alarms undermine security
The one thing that undermines any security system, no matter how sophisticated, is a false alarm.
To be effective your security protection needs to be reliable. Not only do false alarms become a nuisance, they lead to real events being ignored. Worst case staff get fed up with false alarms and turn off the system.
At APS we believe in providing robust, simple to maintain, easy to integrate PIDS. With an industry beating false alarm rate you can be sure that if the system generates an alarm it needs to be taken seriously.
