What is a key advantage of dual tech motion sensors in security systems?

The key advantage of dual tech motion sensors in security systems is their ability to combine microwave and infrared technologies. This combination allows them to significantly reduce the likelihood of false alarms. Microwave sensors are effective in detecting motion over a wide area, while infrared sensors detect changes in heat. By utilizing both technologies, dual tech sensors require two separate triggers to activate an alarm, which enhances their reliability. If either technology does not detect activity, the alarm will not be triggered, helping to minimize incidents caused by harmless movements, such as pets or environmental changes. This dual-detection feature makes them particularly useful in a variety of settings where false alarms may be disruptive or lead to complacency regarding security.
