Kingslim 3-Channel Dash Cam O3PRO

A drive can involve more than what happens in front of the windshield: activity in the cabin or behind the car may matter too. The Kingslim O3PRO records front, interior, and rear views at once, with a higher stated resolution for the front camera than for the other two.

It can also be set up for front-and-rear or front-and-cabin recording, so the three-camera layout is not the only way to use it.

How to use it

For a drive where you want footage from several angles, the O3PRO records the front at 2.5K and the interior and rear at 1080P each. Picture a commute with a close following vehicle: the rear camera covers the view behind, while the front camera records the road ahead. Inside the cabin, infrared night vision switches on automatically in low light, which may be useful for capturing interior footage after dark.

Prefer fewer views? The camera also supports front-and-rear or front-and-cabin recording, with the front at 2.5K and the other selected view at 1080P. Its 2-inch screen offers multiple display modes, and 5GHz Wi-Fi plus phone-app control are listed for viewing and managing clips on iOS or Android. What does the faster wireless connection change in everyday use? It is intended to make downloading and sharing footage more convenient, Kingslim describes it as four times faster than 2.4GHz Wi-Fi, but that figure is a stated comparison, not a guarantee for every phone or connection.

Pros

• Three simultaneous views give more coverage than a basic front-only dash cam, including a dedicated cabin view.
• Automatic interior IR night vision is designed for low-light cabin recording.
• A 64GB memory card is included, and loop recording overwrites older footage when the card is full.
• The G-sensor can trigger emergency recording when it detects sudden movement or a collision, helping protect important footage from routine loop overwriting.

One practical tradeoff is resolution: only the front camera records at 2.5K. The interior and rear cameras record at 1080P, so buyers who want matching higher-resolution footage from every angle will not get that here.

Spec sheet

• Name: Kingslim O3PRO
• Type: Three-channel dash cam
• Resolution: Front 2.5K, interior and rear 1080P each
• Display: 2-inch screen with multiple display modes
• Memory: 64GB card included
• Wireless and app control: 5GHz Wi-Fi, iOS and Android app support

Loop recording keeps footage cycling as storage fills, while the G-sensor is intended to flag sudden movement or collisions for emergency recording. The supplied card has a defined capacity, so footage is not an unlimited archive: older recordings are overwritten as the card fills unless protected as emergency footage.

Final verdict

You’ll appreciate it if you want to record the road, cabin, and rear view in one setup, or switch to a front-plus-one-camera arrangement. Compared with a simpler front-only camera, the extra viewpoints offer more context, compared with a more resolution-focused setup, the compromise is clear: the front gets 2.5K, while the other views are 1080P. It’s not for you if equal 2.5K detail across all cameras is essential. The included card, app access, and automatic interior night mode make the feature set practical for everyday recording, but storage still cycles through older footage. Choose it for coverage across the car, not for three matching high-resolution feeds.
