The most effective security systems utilise a combination of tools and technologies, including closed-circuit television, physical and electronic access control systems and a robust intruder alarm system connected to an intervention system.
Even before the smart security revolution made possible by the Internet of Things, businesses noticed that the most effective security systems were those that were interconnected.
This typically meant security sensors, locks and access control systems that were linked to intruder alarms, security staff and, if necessary, emergency services.
However, these systems need to be perfectly calibrated for the particular environment they are installed in, and need to factor in acceptable everyday events which could theoretically set off the alarm system.
Too lax a security approach and the system proves to be ineffective, but too sensitive an approach can leave it prone to false alarms, which can be just as counterproductive.
Here are some common causes of false alarms.
Environmental Factors
Security alarms typically rely on a range of sensors that track motion in various ways, but outside motion sensors need to be calibrated so that they will not mistake common aspects of the environment as potential intruders.
Insects, rain, swinging branches and stray animals will often be picked up by motion sensors, but with appropriate calibration and installation by professionals, the number of false alarms can be minimised.
Many modern systems use a two-step verification process, alerting security staff but requiring verification before sounding an alarm.
Protocol Issues
Effective security is a matter of not only using the most appropriate technological solutions but also ensuring that the particular site has a security-first mentality.
Whilst this is sometimes characterised as user error as it usually involves improper activation of alarms, often the root cause is not the actions of an individual but potential issues with the particular routine operated by staff members or inadequate training.
New security systems and new security staff must be trained in how the systems work, how they are activated and primed, and ensure that there are appropriate contacts for the monitoring team so they can receive and respond to alerts in a timely fashion.
The more robust your security protocols, the less likely false alarms are, which can have the consequence of slowing down the response of the police or security services.
Power Management
Some alarm systems are designed to activate if there is a power outage, as cutting the power is a common tactic for intruders and activating functions as a failsafe using battery power.
This can be a problem if, however, you have issues with power outages, surges or interruptions. One way around this is to take advantage of an uninterruptible power supply, which ensures that the security system has a consistent and stable power supply.
Wear And Tear
Over time, some of the sensors and detectors can become old and obsolete, sending irregular systems which can cause false alarms to activate.
This can be easily fixed through professional installation and routine maintenance of the system as a whole, with the ability to make adjustments as and when required.
