電池式的攝影機/門鈴如何喚醒?
為了省電,攝影機通常處於休眠狀態(低功耗)。APP進行設定,比如攝影機的即時觀看,可以喚醒攝影機。並且它也可以被PIR感應器喚醒。
PIR感應器是指被動紅外線感應器。「被動」是指PIR設備本身不會輻射。它們透過偵測物體發射或反射的紅外線來運作。
攝影機有雙感應器,當人或動物經過攝影機的偵測區域時,雙感應器會偵測到紅外線輻射的變化,來喚醒攝影機。頻繁的熱源移動會導致攝影機被頻繁喚醒。因此PIR感應器可能會受到環境的影響。由於感應器的機制,它們可能無法在某種程度上偵測到直接向攝影機移動的物體。
注意:偵測區域或隱私區域不會影響PIR感應器,因此這些這定不能減少喚醒時間。
什麼是喚醒靈敏度?
通常喚醒靈敏度是指攝影機對PIR感應器觸發的靈敏度。更高的靈敏度導致更遠的偵測距離、更容易喚醒與更多記錄,這將減少電池壽命。
您可以根據您的需要和特定環境調整靈敏度。在攝影機設定>偵測與警報>偵測靈敏度。
