Reliable DetectionCCTV cameras use two main methods of detection, PIR sensor and motion-in-picture detection. Whilst both these detection methods would work fine indoors, they are extremely prone to false alarms in an outdoor environment. PIRs are basically a 'heat change' sensor and will trigger when seeing small animals, vegetation moving in the wind and harsh weather conditions. Motion-in-picture is just that, thus movement of benign objects will trigger an alert. The only reliable outdoor detection method is an infrared
point-to-point beam. Only something solid like a person or vehicle will cause an alert. |
