Dashcam Hardwire Kit Installation (Canada): Fuse Tap + Voltage Cutoff
Write your post here…
Quick answer: A hardwire kit gives constant power for parking mode and protects your battery with a low-voltage cutoff. The most common mistake is choosing the wrong fuse circuit.
Before you start
- Choose a kit with low-voltage cutoff.
- Use fuse taps that match your vehicle fuse type.
Which fuses to use
- ACC fuse: turns on with ignition (camera normal driving mode).
- BATT constant fuse: always on (parking mode power).
Common mistakes
- Using a constant fuse for both wires (parking mode acts weird).
- Bad ground point (random resets).
- Cutoff set too high (parking stops too early in winter).
Canada voltage tips
- Winter reduces battery voltage — expect earlier cutoff.
- Try 12.0V–12.2V for overnight parking depending on your battery health.
