IIWEY N5 4 Channel Dash Cam Review: Does 360° Coverage Actually Work?

Ever been in a fender-bender where the other driver pointed the finger at you? A front-only camera leaves out everything that hits you from the side, and it shows nothing of what happens inside the car.

The IIWEY N5 4 Channel Dash Cam is a 360° system that records the front, rear, both sides, and the interior of your vehicle at the same time, all onto a single SD card. At $109.99 with a 4.4-star rating across 3,304 Amazon ratings, it aims to cover the angles a single-lens dashcam misses.

I ran this setup across multiple commutes and a late-night rideshare run to see whether the four-channel coverage holds up in real driving. The interior IR and the app transfers were the two things I most wanted to stress-test.

The short version? For the money, this dash camera delivers genuine full-car coverage with strong interior night vision, though a couple of catches are worth knowing before you buy.

What I Liked

The IIWEY N5 impressed me in several practical areas across my testing. Here’s what stood out.

True 360° Coverage: Front, Rear, Side, and Interior Cameras

Four 1080p cameras — front, rear, interior, and dual side views — record simultaneously onto one SD card. The front and rear cameras shoot at 170° wide while the side cameras cover 150°, so there’s no real blind spot around the car. For checking tight spots like door frames or under the dash during install, a DEPSTECH DS620 Triple Lens Endoscope gives DIY installers a clear view where a wide angle dash cam lens can’t reach.

If someone sideswipes you, a passenger damages something, or a parked car taps your bumper, there’s footage of it. One r/Dashcam owner posted clips of a real near-miss the N5 caught on a commute. Before you even wire up a dash cam, a CM-205FN Paint Thickness Gauge can help used car buyers confirm a vehicle’s paint hasn’t been touched up to hide prior damage.

170° Wide-Angle Lenses With a 1080P x4 / 2.5K Front Option

The N5 runs a straight 1080P x4 mode, or a 2.5K + 1080P + 1080P + 1080P mode that bumps up clarity on the 1080p front camera specifically. The 170° wide-angle lens on the front and rear pulls in a lot of road on each side. It doesn’t shoot 4K — the front tops out at 2.5K — but for reading plates and holding lane position, the extra front resolution helps.

8 IR Lamps Deliver Clear Interior Night Vision

Eight infrared lamps are built into the front unit and aimed at the cabin. At night the inside of the car records clearly even with the lights off, which matters most for the interior camera. License plates and road signs out front and back also come through cleanly after dark.

5GHz WiFi and App Control for Fast Clip Transfers

The 5GHz WiFi (with 2.4GHz support) pairs with the free iiwey or viidure app for iOS and Android. Because 5GHz is roughly four times faster than 2.4GHz, pulling clips onto your phone after an incident moves quickly instead of crawling. You can swap between camera views, save photos, and download clips without ever removing the SD card.

Supercapacitor Design Built for Extreme Heat

Instead of a lithium battery, the N5 uses a supercapacitor rated to run from -4°F to 167°F. That means no battery to swell, melt, or die in a car baking in summer heat. For a device that lives on your windshield year-round, this is the right call.

128GB SD Card and Loop Recording Included

A 128GB microSD card ships pre-installed, and the camera supports cards up to 256GB. Loop recording runs continuously in high-definition video and overwrites the oldest footage once the card fills, so no seconds are missed. Having the memory card in the box means you’re ready to record out of the gate.

G-Sensor Locks Emergency Footage on Impact

The built-in G-sensor watches for a sudden collision while you drive. When it detects one, it locks a 10-second clip into a separate emergency folder so loop recording can’t overwrite it. The evidence is just there, locked the instant something happens, without you having to think about it.

What Needs Improvement

No product is perfect, and the N5 has a few limitations worth knowing before you buy. Reliability is also mixed: Amazon’s own AI review summary flags 102 of 314 reliability mentions as negative, about 32%, with some owners reporting devices that stop working.

Parking Mode and Time-Lapse Recording Need a Separate Hardwire Kit

The N5 offers two parking modes — time-lapse at 1fps to save storage, and impact-triggered locking — but 24-hour parking protection requires a hardwire kit (ASIN B0DHJNRPB9) that is sold separately and not in the box. Several r/Dashcam owners also report parking-mode loop recording overwriting overnight footage before they can retrieve it in the morning. At least one owner found parking mode only worked once enabled through the IIWEY app specifically, not the device menu, which caused real setup confusion.

If overnight monitoring is your main reason to buy, budget for that hardwire kit from the start.

No GPS or OBD Support for Speed and Location Data

The N5 has no GPS and does not support an OBD connection, so your footage carries no speed or location stamps. For everyday evidence of who hit who, that’s fine, but if you need GPS-tagged video for fleet tracking or insurance telematics, this isn’t the pick. It’s a common gap on budget four-channel systems, and worth factoring in up front.

WiFi Only Works Reliably on the Included Lighter Charger

The WiFi power requirement is a genuine gotcha. If you skip the included cigarette-lighter charger and plug the camera into a random USB or type-C cable, the WiFi keeps cycling and won’t connect to your phone. It can make the camera seem broken when it isn’t — you just need the included lighter adapter.

How It Compares

The four-channel dash camera market has options at every tier. Here’s how the IIWEY N5 stacks up against a few common alternatives.

vs Vantrue N5

Vantrue’s N5 sits a tier up, with a higher 2.7K front resolution and Starvis 2 sensors that pull ahead in low light, plus a more polished parking mode. It also costs notably more than the IIWEY N5. If night-time image quality is your priority and you’ll pay for it, the Vantrue is the stronger camera; if you want full 360° coverage for around $110, the IIWEY makes more sense.

vs Viofo A139 Pro / A229 Pro

The Viofo A139 Pro and A229 Pro are frequent r/Dashcam top recommendations for image quality and reliability, built around Sony Starvis 2 sensors. They’re positioned well above budget entrants like the N5, with easier installation and cleaner video. Choose the Viofo if consistent image quality and long-term reliability matter most; the N5 counters with a lower price and a dedicated interior camera the Viofo pairs don’t emphasize.

vs Wolfbox G900 Pro

The Wolfbox G900 Pro is another multi-camera option, and its owners run into the same parking-mode configuration headaches that N5 buyers describe. That’s a category-wide pain point, not a flaw unique to IIWEY, so between the two it comes down to price and which app ecosystem you trust more. Once you’ve settled on a camera, a tomtoc Organizer Pouch keeps the spare SD cards and charging cables that come with it from cluttering your glovebox.

For drivers who want front, rear, side, and interior coverage — including a rear backup camera view — without stepping up to premium pricing, the IIWEY N5 holds its ground.

Final Verdict

The IIWEY N5 delivers genuine 360° coverage and strong interior night vision at a price that undercuts the premium tier.

I’m giving it a 3.9 out of 5.

It earns high marks for four-channel coverage, IR night vision that works, fast 5GHz WiFi, and a heat-proof supercapacitor design. It loses ground on mixed reliability reports, the lack of GPS, and a parking mode that depends on a hardwire kit sold separately.

Bottom line: If you want affordable full-car coverage for rideshare or daily driving, the N5 is worth a look. Just use the included lighter charger from day one, and budget for the hardwire kit if parking mode is why you’re buying. Check the current price on Amazon before deciding.
