Vantrue N4 Pro S User Manual & Troubleshooting Guide
Vantrue N4 Pro S acting up? Lost the booklet? No stress.
If your dash cam is beeping at you or you just can't remember the voice commands, you've come to the right place. We've pulled together the official manual, a quick troubleshooting table, and some expert tips to get your Vantrue N4 Pro S sorted without the headache.
💡 Pro Tip: Unlock 24/7 Parking Mode
The N4 Pro S has an incredible "Buffered Parking Mode," but it won't work with just the cigarette lighter cable. To catch hit-and-runs while you're parked, you need to hardwire it to your car's fuse box.

Troubleshooting & Indicator Lights
The N4 Pro S uses specific LED behaviours and voice prompts to tell you what's going on. Here is the cheat sheet so you don't have to guess.
| Indicator / Issue | Meaning & Fix |
|---|---|
| Blinking Blue Light | All Good. The camera is recording normally. If it stops blinking, you aren't recording! |
| Solid Blue Light | Standby Mode. The camera is powered on but NOT recording. Check if your SD card is full or requires formatting. |
| "SD Card Error" | This beast records 3 channels at once (Front, Interior, Rear). A cheap card can't keep up. Fix: Format the card inside the camera menu. If it persists, you need a U3/V30 High Endurance card (Samsung Pro Endurance or Vantrue brand). |
| Rear Camera Disconnecting | Common issue if the cable is pinched. Check the connection at the main unit. Fix: Update to the latest firmware from the Vantrue website-they recently patched a bug related to rear cam detection. |
| WiFi Connection Failed | Phones often drop the dash cam WiFi because it has no internet. Fix: Turn off "Mobile Data" on your phone before connecting to the Vantrue App. |
Common Questions (Aussie Expert Answers)
Q: Why does my N4 Pro S turn off when I turn off the car?
A: That’s standard behaviour, mate. The cigarette lighter port usually loses power with the ignition. If you want it to stay on and record bumps while you're shopping, you need that Hardwire Kit we mentioned above.
Q: What are the voice commands?
A: You can yell at it to keep your hands on the wheel. The most useful ones are:
"Take Photo"
"Lock the Video" (Saves the clip to the Emergency folder)
"Turn on Audio" / "Turn off Audio"
"Show Rear Camera"
Q: My screen goes black after 3 minutes! Is it broken?
A: Nah, that’s just the "Screen Saver" setting so the light doesn't blind you at night. It’s still recording (look for the blinking blue light). You can turn this off in the System Setup menu if you prefer the screen always on.
