How to Reduce False Alarms

How to Reduce False Alarms With Pelco Calipsa Pro Analytics.

How to Reduce False Alarms – According to Peter Ha, product manager at BGW Technologies, cutting false alarms should be a priority on every project.

“When it is done well, false alarm filtering enables teams of any skill level respond faster. It helps to reduce alert fatigue and lets operators focus on the threats that matter.”

“Pelco Calipsa Pro Analytics is a practical AI false alarm filtering solution that integrates with existing cameras and can reduce false alarms by as much as 90 per cent” explains Ha.

“It sets up rules to focus on genuine events, draws on your customers’ existing camera network, and identifies objects with up to 99 per cent accuracy.”

According to Ha, a security system designed to reduce false alarms can make a real difference, providing one of the clearest ways to add real value to a deployment.

“Physical security systems exist to protect people and property, and false alarms are one of the biggest operational challenges in security,” says Ha.

“When an alarm goes off every time a cat walks past or a tree sways users often lose confidence in the system and often end up switching off notifications altogether. This reaction completely negates the benefit real-time notifications bring and worse still, this is when real threats tend to slip through.”

According to Ha, the scale of the false alarm problem and its impact on security system use is concerning.

“Industry research suggests that up to 98 per cent of security alarms turn out to be false,” he explains. “The good news is that AI-powered false alarm filtering technology has matured and BGW Technologies, as an Australian wholesale distributor of Pelco, works with integrators every day to specify systems that keep control rooms focused on the events that matter.”

“Modern false alarm filtering uses AI-powered video analytics to separate out real threats from harmless activity in live footage, and it can reliably tell the difference between a suspicious vehicle or an unknown person or environmental events like swaying trees or a passing animal. The important part is that it only escalates to operators when action is genuinely needed.”

BGW Technologies offers pre-sales support and factory-trained technical expertise to help installers and integrators specify and deploy Calipsa with confidence.

Typical AI filtering Workflow:

Typical AI filtering workflowFive passes between the camera and the operatorEach stage discards activity the next stage doesn’t need to consider.
1ClassificationExamines live footage and reference data to identify what triggered the alert
2Contextual analysisCompares movement against wider data to separate expected from suspicious
3SchedulingChecks user-defined zones and schedules — high-risk area, concerning time of day
4VerificationDraws on other devices, such as motion and sound sensors, before alerting
5LearningMachine learning gradually adapts to site-specific patterns over time
ALL MOTION EVENTSESCALATED TO OPERATOR12345volume falls at every pass
Worth noting: stages 3 and 4 are configuration and integration, not AI. Zones, schedules and sensor inputs are set by whoever commissions the system — which is where an integrator’s decisions, rather than the algorithm, determine how well the filtering performs.
