監察喺你部機上面發生。 Monitoring that stays on your device.
所有偵測同錄影都喺 iPhone 本機處理。離開 App 就會停——設計誠實，唔會扮可以背景錄影。 Detection and recording run on the iPhone itself. Leave the app and monitoring stops — honest by design, not background recording.
淨係睇你想睇嘅位置 Watch only what matters
最多畫 3 個偵測區域，片長有 5 種（30 秒至無限制）。窗簾郁吓都唔會塞爆相簿。 Draw up to 3 detection zones and choose from 5 clip lengths (30 seconds to unlimited), so a swaying curtain doesn’t fill your library.
唔會焗壞部機 Keeps your phone cool
部機一熱就自動降低解像度同幀率；太熱就暫停錄影，凍返落嚟自動恢復。 If the phone warms up, SpareCam lowers resolution and frame rate. If it gets too hot, recording pauses and resumes once it cools down.
時間表同即時動態 Schedule and Live Activity
設定每日監察時段。即時動態喺鎖定畫面同 Dynamic Island 顯示狀態同今日片段數。 Set a daily monitoring window. A Live Activity shows status and today’s clip count on the Lock Screen and Dynamic Island.
省電同通知 Power and notifications
閒置時可調暗畫面。電池同過熱有提示。本地通知話你知片段儲存、時間表開始或者偵測到動作。 Optional screen dim when idle. Battery and thermal warnings. Local notifications for saved clips, schedule start, and motion.
簡單、老實 Simple and honest
插住電，保持 SpareCam 開喺畫面。開住 App 先會錄；轉 App 或者鎖機就會停。 Plug the phone in and keep SpareCam open. It records while the app is open. Switch apps or lock the phone and recording stops.

常見問題 Questions
SpareCam 可唔可以喺背景錄影？ Does SpareCam record in the background?
唔可以。要開住 SpareCam 喺畫面先會錄。請插住電，保持 App 開啟。 No. SpareCam records only while it’s open on screen. Keep the phone plugged in with SpareCam open.
可唔可以用另一部手機睇鏡頭？ Can I watch the camera from another phone?
正式版唔提供遠端即時睇。SpareCam 喺部機本身錄影；錄咗嘅片喺「相片」度睇。 The shipping build does not offer remote live view. SpareCam records on the device; review clips in Photos.
啲片存喺邊？ Where are my videos stored?
存喺你 iPhone「相片」嘅 SpareCam 相簿。除非你分享或者用 iCloud 相片，否則唔會離開部機。 In a SpareCam album in your iPhone’s Photos library. They only leave the phone if you share them or use iCloud Photos.
使唔使月費？ Is there a subscription?
唔使。基本功能永久免費。Pro 係一次性購買（USD $4.99，各地區價錢以 App Store 為準），喺設定可以恢復購買。 No. The core app is free forever. Pro is a single one-time purchase (USD $4.99; regional App Store price may vary). Restore anytime from Settings.
部機會唔會過熱？ Won’t the phone overheat?
過熱保護會喺部機變熱時降低畫質，太熱就暫停錄影，凍返自動恢復。請放喺通風、唔會曬到太陽嘅位置。 Thermal protection lowers quality as the phone warms and pauses recording if it gets too hot, then resumes automatically. Keep the phone ventilated and out of direct sun.
係咪保安系統？ Is it a security system?
唔係。SpareCam 並非專業保安系統，請勿用於安全攸關用途。請只喺你有權監控嘅空間使用。 No. SpareCam is not a professional security system. Don’t rely on it for safety-critical use. Only monitor spaces you’re allowed to.
