Overview
本行車記錄器購買指南採用選擇邏輯學，讓您可以看穿解析度/幀率的炒作和夜視功能的高估——真正的組合才是重點，而不是規格表上的數字（T1 匹配定理）。
Theory anchor: 好的選擇符合您的駕駛情境（白天/夜晚、高速公路/城市）和證據需求——而不是「最高解析度」或「最佳夜視」行銷。
Step 1 → Need clarification (M1)
使用 M1 需求明確化。
Scenario analysis
| Scenario | Primary considerations |
|---|---|
| Daily commute, incident evidence | stable 1080p, loop recording, card compatibility |
| Night, tunnels, underground | night vision, sensor size and aperture, WDR |
| Front + rear, parking mode | dual lens, hardwire, battery/capacitor |
| Simple and reliable | easy install, stability, support and firmware |
Example need list
- Must-have: clear plate and key scene capture, stable no missed recording
- Nice-to-have: usable night vision, storage and loop logic
- Bonus: ADAS, speed alerts, Wi‑Fi export
Step 2 → Allocate cognitive budget (T2)
行車記錄器是中等價值和中等可逆性（決策可逆性）。根據 T2 認知預算定理 和 認知預算：~15 分鐘的需求明確化，~40 分鐘的解析度/幀率和夜視功能基礎知識，~25 分鐘的比較。
Step 3 → Multi-dimensional evaluation (M2)
使用 M2 多維評估。解析度和幀率必須一起考慮：低幀率下的高解析度可能會在運動中模糊；夜間品質取決於感測器尺寸、光圈和處理——而不僅僅是「夜視」標籤。檢查樣本影片和評論，而不僅僅是規格。
| Dimension | Sub-items | Evidence sources |
|---|---|---|
| Sensor & lens | sensor size, aperture, angle and distortion | product info, reviews |
| Resolution & frame rate | actual output res, frame rate combination, bitrate | specs, sample video and reviews |
| Night vision & WDR | low-light performance, WDR/HDR, supplemental light | night samples, user feedback |
| Storage & stability | loop recording, card compatibility, overheating and lockups | manual, forums and reviews |
權重範例（根據 T1 匹配定理）：感測器和鏡頭 25%；解析度和幀率 25%；夜視功能和 WDR 30%；儲存和穩定性 20%。
Step 4 → Bias & persuasion hazards
- Resolution/frame rate hype: 60K 或 60fps 可能僅適用於某些模式，或在高解析度下使用較低的幀率；避免錨定效應在大數字上——檢查實際輸出組合和位元率。
- Night vision overclaim: Many “night vision–modes just brighten with software; real-world noise and plate readability matter—night quality depends on sensor and aperture, not marketing; avoid 光環效應 (brand or keyword = good).
- Authority bias: “Certified–or 0–1 in test–should be checked against test conditions; rely on sample footage and your use case.
Step 5 → Decision + validation (M5)
使用 M5 決策驗證：檢查清單（解析度/幀率適合白天/夜晚和高速公路/城市，適配分，夜間樣本顯示可讀的車牌，根據 T4.2 滿意即可）。1-3 週後檢查需求一致性（播放白天和夜晚可用，沒有遺漏的錄音或鎖定，後悔）。
