Alarms Causes of false positives and false negatives
When using the alarm, have you ever encountered false alarms or false negatives? There may be some people who have encountered it. So what is the reason for this phenomenon? What are the main reasons for infrared detection alarms to cause false positives and false negatives?
Wireless detectors have poor anti-interference ability, which is easy to cause false positives and false negatives.
Infrared detectors are not accurate enough to cause false positives or false negatives.
Because both the host and the detector are wirelessly encoded, the encoding is duplicated, causing the host and detector to re-code the false positives. There are also some alarms whose quality is too bad, such as component damage and poor production process, causing false alarms, as well as the selected equipment, installation method, angle, and position. There are also artificial factors such as improper operation of the user, accidental triggering of the alarm, misunderstanding, and accidental entry into the defense zone. In fact, the causes of false positives and false negatives are more complicated.
