- What do the three channels record?
- Typically the road ahead, the cabin interior and the rear. That gives front, in-car and rear coverage from one system.
- Does it need a memory card?
- Yes. Dash cams record to a microSD card, which is usually sold separately. Use a high-endurance card rated for continuous recording.
- Can I view footage on my phone?
- Yes. App control is listed, so you connect over Wi-Fi to view and download clips. Expect slower transfers for large files.
- Is it hard to install?
- Three cameras mean more wiring than a single front unit, especially routing a cable to the rear. Professional installation is worth considering.
- Does it record while parked?
- Parking mode usually requires a hardwire kit or a constant power source. Check the manual, since it is not confirmed for this model.
- How does it compare with a single front dash cam?
- It covers more angles, which matters for rideshare and collision disputes, but costs more and takes more setup than a basic front-only camera.
