Vantrue N4S User Manual & Troubleshooting Guide
Vantrue N4S acting up? Lost the booklet? No stress.
You’ve picked up the Vantrue N4S - solid choice for 3-channel protection. But if you’re staring at a blinking blue light or wondering why your rear camera is playing hide and seek, you just want answers, not a 50-page lecture. We’ve stripped out the fluff and kept the gold info below so you can get back on the road sorted.
💡 Pro Tip: Unlock 24/7 Protection
Your N4S has a "Parking Mode" that watches your ute while you're at the pub or asleep, but it won't work with just the cigarette lighter cable. You need a constant power source that knows when to cut off so your battery doesn't go flat.
We recommend: The Official Vantrue Type-C Hardwire Kit. It’s a literal plug-and-play solution for peace of mind.
Troubleshooting Cheat Sheet
Don't guess what the flashing lights mean. Here is the quick translation guide for the N4S.
| Indicator / Issue | Meaning | Fix It |
|---|---|---|
| Blue Light Blinking | Recording in progress | No worries - this is normal operation. |
| "SD Card Error" | Card unformatted or too slow | Format the card inside the camera menu. Ensure you are using a U3 / Class 10 / A2 card (Max 512GB). |
| Rear Camera Black | Loose connection | Unplug and firmly re-seat the rear cable at the front unit. It often needs a solid "click". |
| Stops Recording Randomly | G-Sensor too sensitive | Your card is full of "Locked" videos. Lower G-Sensor sensitivity to "Low" and format your card. |
Common Questions (Sorted)
Q: How do I actually turn on Parking Mode?
A: It's in the menu under "Record Setup," but here's the catch: if you don't have a Hardwire Kit (like the one linked above), the camera will just turn off when you kill the engine. You need continuous power to keep it in "sentry" mode.
Q: Why does my screen turn off while I'm driving?
A: That's the "Screen Saver" feature. The camera is still recording (check for that blinking blue light). If you want the screen always on, head to System Setup > Screen Saver and set it to "Off."
Q: Can I view footage on my phone?
A: Too right. Download the official Vantrue App (Android or iOS), enable Wi-Fi on the N4S (long press the Wi-Fi button or find it in the menu), and connect your phone to the camera's Wi-Fi network (default password is usually 12345678).
