iQ 4K Smart Dash Camera

When it comes to dash cams, most simply just record locally while the car is on and you are driving. However, after seeing a few hit and runs in the parking lot this summer, I knew I wanted something more to give me peace of mind.

Something with smarter safety features, and reliable protection whether my car is on the road or parked at the curb. The Nextbase iQ 4K Smart Dash Cam promises to deliver exactly that, positioning itself as not just a camera, but a complete in-car security system.

Packed with AI-powered monitoring, 4K video quality, and always-on 4G connectivity, it’s designed to set a new benchmark for what a dash cam can do. After spending time with the iQ and exploring its advanced features, here’s how it stacks up in real-world use.

Overview

From the official Nextbase site, the iQ is branded as “the world’s first truly Smart Dash Cam,” available in 1K, 2K, and 4K versions. Its key selling points include:

Advanced AI‑Driven Features: Roadwatch AI for anticipatory threat detection; Smart Sense Parking with spatial-awareness; voice‑activated Witness Mode, Guardian Mode, and Emergency SOS.

Connectivity: Always-on 4G LTE connection for live‑view, smart alerts, remote access, and cloud storage.

High‑Definition Recording: The 4K model captures the front view in 3840 × 2160 with 140 degrees field of view, with built‑in cabin recording in 2K (180 FOV), and optional rear-camera support.

Convenient Kit: It comes with a 64 GB microSD card and installation cables (OBD power and hardwire).

Video Quality & Design

The 4K iQ video performance delivers exceptional clarity both day and night with an impressive dynamic range and enhanced infrared night vision for capturing detail in low light without blowing out exterior views.

The iQ features a distinctive circular mount with a stiff hinge, making it easy to mount with a strong hold. While visually sleek, the mount itself is a bit long, so finding the right position can be a little tricky. The 222 Dash Cam we reviewed had a much smaller blueprint for those looking for something smaller with less “smart” features.

The setup process was pretty seamless. Simply scan the code on the box to download the Nextbase iQ app, create an account, scan the code on the camera to allow connection and instant operation. 

Once connected, you can then mount the camera while viewing the live feed on your phone, then run the wires down to the OBD port. You can also add an additional rear view camera for extra coverage and peace of mind.

The camera records locally to an SD card, but you can also opt in for cloud storage with a paid subscription and more smart features.

Smart Features & Connectivity

The app is intuitive and easy to use. When the rear camera is connected, you have 3 viewing options. You can click on each camera view to enlarge it, download the footage to your phone, and adjust any smart settings like Emergency SOS, Witness Mode, and Guardian Mode.

Safety & Monitoring Capabilities like lane departure, collision warnings, and driver monitoring is what really makes this camera “smart”. If a crash is detected, the iQ will share your location and medical details (such as blood type) with emergency personnel so you can quickly get the help you need without lifting a finger.

With 4G LTE and Nextbase’s app, you get real-time alerts, live view, and remote communication—valuable for monitoring your vehicle from anywhere. With “Witness Mode” enabled, you can say “Hey Dash Cam, start Witness Mode” and your designated emergency contacts will receive a link via email and SMS, allowing them to watch live footage.

This feature is great if you get stopped by the police or you are in an area that feels unsafe. You’ll have someone watching over you and able to make a call right away if something happens.

The Guardian mode is great for parents that share their car with their teens that drive. You can set speed limit and location alerts and chime in when your kid is driving too fast or goes outside a specific area.

Core functions are accessible without cost, but the advanced capabilities listed above—like cloud backup, SOS, Witness Mode, and full smart alerts—require a paid subscription. Plans range from $10 to $20 per month.

Cost & Value

Priced at $499.99 for the 1K model, $599.99 for 2k, and $699.99 for 4K, this camera is positioned as a premium offering. While you can use this camera without a subscription, the main reason to get a “smart” dash cam is to use the smart features. So if you are willing to make the investment in the hardware, make sure you leave room for subscription costs to utilize the full capabilities of this camera. For those who simply need to just record video, then I suggest checking out the 222 Dash Cam. But for those who want a complete solution with a ton of safe guard options, the iQ 4K Smart Dash Cam, is the way to go.

Final Verdict

The Nextbase iQ 4K Smart Dash Cam is undeniably one of the most sophisticated dash cams available today. It excels in video performance, smart safety features, and always-on connectivity. If you’re looking for a high-end, always-connected in-car security system—and are comfortable paying for monthly access—it’s a standout choice.
